Both of us would be attracted towards each other due to the force of gravity with a specific magnitude of 2.4 x 10^-13 N-that number is calculated using the formula for gravitational force and inputting 1KM for r^2.
What is gravitational force?Gravitation or just gravity is the force of attraction between any two bodies. All the objects in the universe attract each other with a certain amount of force, but in most of the cases, the force is too weak to be observed due to the very large distance of separation. Besides, gravity’s range is infinite, but the effect becomes weaker as objects move away.This force of attraction was first observed by Sir Isaac Newton and was presented as Newton’s law of gravitation in the year 1680. However, gravitation can generally exist in two main instances.Gravitation may be the attraction of objects by the earth.To learn more about gravitational force refer to:

enrique is given information about what causes a satellite to move tangentially to a circular path? air resistance friction inertia gravitya satellite orbiting earth. r
Because of the inertia of the satellite's motion, it will proceed tangentially to its circular orbit at the same speed, or V.
The satellite will deviate from its course with its tangential velocity because there won't be any centripetal force to keep it in a circular orbit in the absence of gravitational force. Accelerations at the centripetal axis are produced by centripetal forces. Any satellite's circular motion around a celestial body, with the exception of the Earth's rotation around the Sun, is caused by the centripetal force generated by their mutual gravitational attraction. Over the course of an orbit, tangential speed varies. The satellite's velocity and centripetal force are at right angles. With growing satellite separation from Earth, tangential speed rises. Centripetal force may occasionally slow.

What is gravity?The force that pulls items toward the centre of a planetary or other body is known as gravity. The gravitational pull maintains each of the planet in orbit about the sun. The degree to which a coordinate in space-time is invisibly bent determines the intensity of the gravitational "field" at any given place in space or time. Massive items tumble down these bends in the direction of one another. The stronger the attraction between items, the more matter there is, and the closer together things are. And unlike electricity and magnetism, which may either repel or attract, gravity always draws objects together.

a) The effective radiating temperature of a cube-shaped planet can be described by the equation: T_eff = (S_absorb / S_emit)^(1/4) * T_sun, where T_eff is the effective radiating temperature, S_absorb is the surface area through which the cube absorbs radiation, S_emit is the surface area through which the cube emits radiation, and T_sun is the temperature of the sun.
What is radiating temperature?The effective radiating temperature of a planet is a measure of the temperature at which the planet emits radiation to its surroundings. It can be determined by considering the ratio of the surface area through which the planet absorbs radiation to the surface area through which it emits radiation. This ratio can be represented by the equation T_eff = (S_absorb / S_emit)^(1/4) * T_sun, where T_eff is the effective radiating temperature, S_absorb is the surface area through which the planet absorbs radiation, S_emit is the surface area through which the planet emits radiation, and T_sun is the temperature of the sun. The fourth power in the formula shows that the temperature of the planet is highly dependent on the ratio of absorbed to emitted radiation.In the scenario described, the Earth has been transformed into a cube and one of its faces always facing the sun. The temperature throughout the cube is assumed to be uniform. To find the effective radiating temperature of this cubed Earth, we would need to know the specific values of S_absorb and S_emit.

A first solution is created by adding the maximum amount of Lead Nitrate that can be completely dissolved at 30°C to 10 grams of water. A second solution is created by raising the temperature to 60°C and adding the maximum amount of Lead Nitrate that can be completely dissolved. What is the percent increase in amount of lea nitrate from the first solution to the second?
The percent increase in amount of lead nitrate from the first solution to the second is 5.55%.
How does the temperature of lead nitrate affect its physical properties? As the temperature of lead nitrate increases, its physical properties change. At room temperature, lead nitrate is a white, odorless, crystalline solid. When heated, lead nitrate will decompose and form a yellow-brown powder of lead oxide and nitrogen dioxide. As the temperature continues to increase, the lead oxide will become molten and eventually vaporize, leaving behind a white, insoluble solid. At high temperatures, lead nitrate will react with moisture in the air to form a yellow-brown lead oxide and nitrogen dioxide gas. This gas can be dangerous if inhaled in large amounts, and can cause respiratory irritation. Additionally, the lead oxide can form a fine dust that is hazardous if inhaled. The melting point of lead nitrate is 305°C, and its boiling point is approximately 443°C. At temperatures above these, the physical properties of lead nitrate become increasingly unpredictable and can be hazardous.To learn more about lead nitrate refer to:

A 0.060 kg tennis ball, moving with a speed of 5.50 m/s, has a head-on collision with a 0.090 kg ball initially moving in the same direction at a speed of 3.00 m/s. Assuming a perfectly elastic collision, determine the speed and direction of each ball after the collision.
The speed and direction of each ball after the collision is :
a) Speed of the first ball after the collision = 2.5 m/s same initial direction
b) Speed of the second ball after the collision = 5.0 m/s same initial direction
A collision in physics is any situation in which two or more bodies quickly exert forces on one another. Despite the fact that the most common usage of the word "collision" refers to situations in which two or more objects clash violently, the scientific usage of the word makes no such assumptions.
Let us consider the initial direction of velocity of the first ball as the right side which we will take to be positive.
The second ball is moving in the same direction as that of the first ball therefore it's velocity is also directed to the right.
Mass of the first ball = [tex]M_{1}[/tex] = 0.06 kg
Mass of the second ball = [tex]M_{2}[/tex] = 0.09 kg
Initial velocity of the first ball = [tex]V_{1}[/tex] = 5.5 m/s
Initial velocity of the second ball =[tex]V_{2}[/tex] = 3 m/s
Velocity of the first ball after the collision = [tex]V_{3}[/tex]
Velocity of the second ball after the collision = [tex]V_{4}[/tex]
The collision is elastic.
Coefficient of restitution = e = 1
e = [tex]\frac{V_{4} - V_{3}}{V_{1} - V_{2}}[/tex]
1 =[tex]\frac{V_{4} - V_{3}}{5.5 - 3}[/tex]
2.5 =[tex]V_{4} - V_{3}[/tex]
[tex]V_{4} = V_{3} + 2.5[/tex]
By conservation of linear momentum,
[tex]m_{1}V_{1} + m_{2}V_{2} = m_{1}V_{3} + m_{2}V_{4}[/tex]
(0.06)(5.5) + (0.09)(3) = [tex](0.06)V_{3} + (0.09)(V_{3} + 2.5)[/tex]
0.33 + 0.27 = [tex]0.06V_{3} + 0.09V_{3}[/tex] + 0.225

The velocities of the both the balls after the collision are positive therefore the direction of the balls are moving after the collision is the same as the initial direction of motion.

a particle of mass m rests on a rough inclined plane that makes an angle with the horizontal if the coefficient of static friction find the least horizontal force acting transcerse to the slope of the plane that will cause the particle to move
So the least horizontal force that is required to cause the particle to move is:
F = μs * N = μs * mg * cos(θ)
Give explanation to support your answer.The coefficient of static friction, s, multiplied by the normal force, N, exerted on the particle results in the minimum horizontal force, F, needed to move it.
The weight of the particle, mg, multiplied by the cosine of the angle of inclination,, results in the normal force, N:
N= mg*cos()
Therefore, the smallest horizontal force needed to move the particle is:

The mass of the fifth fragment is 0.050 kg. What is its velocity right after the explosion?
The final velocity of the 1.2 Kg cart is 3.1 m/s. The final velocity of the coupled mass of cars can be determined using the conservation of momentum. The final velocity is 10 m/s.
What is momentum ?Momentum of an object is the product of mass and velocity of the object. In a collision, the total momentum is conserved.
Here, initially the carts were rest. Hence, their initial momentum is zero.
then (1.2 kg × v) + (2.5 kg × 1.5 m/s) = 0
then , velocity of 1.2 kg = (2.5 × 1.5)/1.2 = 3.1 m/s.
Similarly the total initial momentum of the two car of mass 6000 kg is equal to the their final momentum.
The initial momentum of the stationary car is zero.
then (6000 kg × 20 m/s) + 0 = (6000 + 6000 kg)v.
The final velocity of the coupled mass v is then calculated as:
v = (6000 kg × 20 m/s)/12000 kg = 10 m/s.
Therefore, the final velocity of the coupled mass will be 10 m/s.

Two identical conducting sphere, fixed in place, attract each other with an electrostatic force of 0.108 N when their center-to-center separation is 50.0 cm. The sphere are then connected by a thin conducing wire. When the wire is removed, the sphere repel each other with an electrostatic force of 0.0360 N. Of the initial charges on the sphere, with a positive net charge, what was the negative charge on one of them?
The negative charge on one of the identical spheres in a pair of conducting, fixed, and attracted to each other by an electrostatic force spheres is -1.00*10^-6 C. We can calculate this using Coulomb's law.
We can begin by using Coulomb's law, which states that the electrostatic force between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them.
Coulomb's law can be mathematically written as:
F = k * (q1 * q2) / r^2
where F is the force, k is the Coulomb constant, q1 and q2 are the charges on the two spheres, and r is the distance between their centers.
Given that the force of attraction is 0.108 N when the spheres are 50.0 cm apart, we can use the Coulomb's law to find the product of the charges on the spheres.
0.108 N = (9 * 10^9 N*m^2/C^2) * (q1 * q2) / (0.50 m)^2
The product of the charges on the two spheres is q1q2 = (0.108 N * (0.50 m)^2) / (9 * 10^9 Nm^2/C^2) = 1.2 * 10^-7 C^2
We can use this value to find the charges on the spheres when they are connected by a thin conducting wire and repelling each other with an electrostatic force of 0.0360 N.
0.0360 N = (9 * 10^9 N*m^2/C^2) * (q1 * q2) / (0.50 m)^2
q1q2 = (0.0360 N * (0.50 m)^2) / (9 * 10^9 Nm^2/C^2) = 4.0 * 10^-8 C^2
Since the product of the charges q1*q2 is now smaller, we can assume that one of the charges (let's say q1) is now smaller and the other charge (q2) is now bigger, hence have opposite charges.
We can use the formula q1q2 = 1.210^-7 C^2 / 4.0*10^-8 C^2 = 3q1q2
q2 = 3q1 and q1q2 = 4*10^-8 C^2
Substituting, we get q1 = (410^-8 C^2) / 3q1 = 1.3310^-8 C
The negative charge on one of the sphere is 1.33*10^-8 C

Assume |g| = 10 m/s^2
A free-body diagram of the block on the frictional part of the surface would show the force of friction acting in the opposite direction to the velocity of the block, and the force of gravity acting downward.
Using conservation of energy, the speed of the block at the base of the ramp can be found by setting the initial kinetic energy of the block (1/245^2) equal to the final kinetic energy of the block (1/2mv^2) and solving for v. v = sqrt((1/245^2)/(1/2*m)) where m is the mass of the block.
Using conservation of energy, the maximum vertical height H of the block on the ramp can be found by setting the initial potential energy of the block (mgH) equal to the final kinetic energy of the block (1/2mv^2) and solving for H. H = (1/2mv^2)/(m*g)
a) The total impulse given to the mass on the spring (mass A) during the brief collision is the product of the force exerted on the mass by the block and the time duration of the collision.
b) The speed of the mass on the spring (mass A) immediately after the collision can be determined using the conservation of momentum.
c) The velocity of the block immediately after the collision can also be determined using the conservation of momentum.
d) The spring constant can be determined by using the equation k = (2*F)/x, where F is the force exerted on the spring and x is the compression of the spring.
To find the horizontal range of the block from the end of the ramp, we can use the equations for horizontal and vertical motion of a projectile, with the angle of launch being 30 degrees, the initial speed being 6 m/s, and the final vertical position being 1m above the end of the ramp.

Friction between two lines is what?The force preventing solid surfaces, liquid layers, and sliding material components from moving in the same direction is known as friction. Friction can take many different forms: The relative lateral movement of two solid surfaces that are in contact is opposed by dry friction.
We have given the Force Constant of spring K= 50 N/m.
At x=-0.02 m, Force =-kx
F= -(-0.02\times 50)= 1N Hence Option (A) will be correct.

earth and space chapter 19 section 1 review answer key why is atmosphiric pressure generally lower beneath a mass of warm
Atmospheric pressure is generally lower under a warm air mass than under a cold air mass because molecules move apart when heated. Fewer particles apply pressure to specific areas.
Atmospheric Pressure:
Atmospheric pressure, also called atmospheric pressure (after barometer), is the pressure in the Earth's atmosphere. Standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa) equal to 1013.25 millibar 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. The atm unit roughly corresponds to the Earth's mean atmospheric pressure at sea level. So the atmospheric pressure on Earth at sea level is about 1 atmosphere.
In most cases atmospheric pressure is approximated by the hydrostatic pressure caused by the weight of the air above the point of measurement. Air pressure decreases with altitude because the air mass above is less as altitude increases. Since the atmosphere is thin relative to the Earth's radius (especially the dense atmospheric layers at low altitudes), the Earth's gravitational acceleration as a function of altitude can be approximated as constant and contributes little to this decline. Pressure is measured as force per unit area in SI units Pascal (1 Pascal = 1 Newton per square meter, 1 N/m2). A column of air with a cross-sectional area of 1 square centimeter (cm2) measured from the mean (mean) sea level to the top of the Earth's atmosphere has an average mass of about 1.03 kilograms and exerts a force. Or a "weight" of about 10.1 Newtons, a pressure of 10.1 N/cm2 or 101 kN/m2 (101 kilopascals, kPa).

During a certain time interval, the net work done on an object is zero joules. We can be certain that the object's final speed was the same as its initial speed.
What is speed?Velocity is the rate and direction of an object's movement, whereas speed is the time rate at which an object is moving along a path. In other words, velocity is a vector, whereas speed is a scalar value. the speed at which an object's position changes in any direction. The distance traveled in relation to the time it took to travel that distance is how speed is defined. The rate at which a distance changes over time is referred to as speed. It has a dimension of time-distance. As a result, the basic unit of time and the basic unit of distance are combined to form the SI unit of speed. Thus, the metre per second (m/s) is the SI unit of speed.
