Answers

Answer 1

The average force exerted on the ball during the collision is 5.3 Newtons.

What is force?

Force is a concept in physics that describes the interaction between two bodies. It is a vector quantity, meaning it has both a magnitude (amount of force) and a direction. Force can cause a change in an object's shape, speed, and direction of motion. Examples of forces include gravity, friction, tension, and electromagnetic forces. Forces can be used to push, pull, twist, and bend objects. Force is measured in newtons (N), and is the product of mass and acceleration. Force is an essential part of understanding the universe and how objects interact with each other.

Momentum is defined as mass multiplied by velocity,
and thus the initial momentum of the ball is 0.2 kg x 34 m/s = 6.8 kg m/s. After the collision, the momentum of the ball is 0.2 kg x 26 m/s = 5.2 kg m/s.
Thus, the change in momentum is 6.8 kg m/s - 5.2 kg m/s = 1.6 kg m/s.
The average force exerted on the ball during the collision can be calculated by dividing the change in momentum by the time of the collision:
Average force = 1.6 kg m/s / 0.3 s = 5.3 N.
This means that the average force exerted on the ball during the collision is 5.3 Newtons.

Answers

The weight of the sphere would be 4.12 x 10^-6 N.

To calculate the weight of the sphere, we need to find the mass of the sphere first, using the equation:

mass = density * volume

The volume of a sphere can be calculated using the formula:

V = 4/3 * pi * r^3

where r is the radius of the sphere.

So,

mass = density * 4/3 * pi * r^3

mass = 1 x 10^18 kg/m^3 * 4/3 * pi * (1 x 10^-5 m)^3

mass = 4.19 x 10^-7 kg

Then we can use the weight formula which is :

Weight = mass * g

Where g is the acceleration due to gravity, which is 9.8 m/s^2.

Weight = 4.19 x 10^-7 kg * 9.8 m/s^2

Weight = 4.12 x 10^-6 N

A sailboat and its crew have a mass of 655kg. If the force on the boat is 895N, what is its acceleration?

Answers

To calculate the acceleration of the sailboat, we need to use Newton's second law of motion, which states that force equals mass multiplied by acceleration (F = ma).

Given that the force on the boat is 895N and the mass of the boat and crew is 655kg, we can rearrange the equation as follows:

a = F / m

where a = acceleration, F = force, and m = mass.

Plugging in the known values, we get:

a = 895N / 655kg

So, the acceleration of the sailboat is approximately 1.37 m/s².

It's important to note that this is only an approximation of the acceleration as the force acting on the sailboat may be subject to change due to wind, water currents, etc. This equation does not take into account the resistance of the water, which is also a force that will act on the boat and will affect its acceleration.

The acceleration of the sailboat is 1.37 m/s² if its crew has a mass of 655kg and the force on the boat is 895N.

According to Newton's Second Law of Motion, acceleration (gaining speed) happens when a force acts on a mass (object). Force is a product of mass and acceleration. An object with a mass changes its velocity in response to a push or pull.

Force is an external agent that has the power to alter the resting or moving state of a body. The measurement of a change in an object's velocity is called acceleration.

The acceleration of the sailboat can be calculated using the formula: acceleration = force /mass

In this case, the force is 895 N and the mass is 655 kg, so the acceleration would be:

Acceleration = 895 N / 655 kg = 1.37 m/s²

Hence we can say the acceleration is 1.37 m/s² if its crew has a mass of 655kg and the force on the boat is 895N.

A particle is moving with a constant speed in a corkscrew tunnel (i.e., it is moving in a circle as it moves forward). When it exits the tunnel, what path will it follow?

Answers

When a particle is moving with a constant speed in a corkscrew tunnel, it is traveling in a circular path as it moves forward. The path followed by the particle is a combination of two motions: linear motion (forward) and circular motion (around the circle).

When the particle exits the tunnel, it will continue to follow the combined path it was on before, which is the path of a helix. The helix is a three-dimensional curve that is the result of combining circular and linear motions, that is, the particle will move forward in a straight line, but also continue to move in a circular path around that line. The shape of the helix is similar to a spiral staircase, as the particle moves forward, it also spirals around the center axis of the tunnel.

In summary, when the particle exits the corkscrew tunnel, it will continue to follow the path of a helix, which is the combination of linear and circular motion.

Which of the following changes occurs naturally in a system over time?
A. Becoming more organized
B. Becoming more efficient
C. Increasing in energy
OD. Increasing in randomness

Answers

Answer: D. Increasing in randomness.

Explanation: The concept related to this change is entropy. Entropy is a measure of the randomness or disorder in a system. According to the second law of thermodynamics, the entropy of an isolated system tends to increase over time. This means that natural processes often lead to an increase in randomness or disorder.

For example, imagine a container of gas molecules. Initially, the molecules may be confined to one side of the container, creating a region of higher concentration. However, over time, the gas molecules will naturally spread out and become more evenly distributed throughout the container. This increase in randomness or disorder corresponds to an increase in entropy.

Answers

The electrostatic force between the two electric charges will be reduced if the first charge is doubled and the second charge is only one third of the original charge.

What is electrostatic force?

Electrostatic force is a force of attraction or repulsion that exists between electrically charged particles. It is one of the fundamental forces of nature and is the result of a fundamental property of matter known as electric charge. Unlike gravity, electrostatic force can either attract or repel particles, depending on whether they have the same or opposite charges. The strength of the force is determined by the magnitude of the charges and the distance between them.

The electrostatic force between the two electric charges will be reduced if the first charge is doubled and the second charge is only one third of the original charge. This is because the electrostatic force is directly proportional to the product of the two charges, so if one charge is increased while the other is decreased, the overall electrostatic force will be reduced.

Answers

The magnitude and direction of the electric field at (0, 8 cm) is 7 µC downwards and towards the positive charge.

The electric field at (8 cm, 0) can be calculated using Coulomb’s law. This law states that the electric field is equal to the charge multiplied by the inverse of the square of the distance between the two charges.

This gives us a magnitude of E = (3 µC + 4 µC) / (8 cm)^2 = (7 µC) / (64 cm^2).

The direction of the electric field is from the negative charge to the positive charge.

The electric field at (0, 8 cm) can be calculated by using the same equation as for the electric field at (8 cm, 0). This gives us a magnitude of E = (3 µC + 4 µC) / (8 cm)^2 = (7 µC) / (64 cm^2).

However, the direction of the electric field at this point is different. At (0, 8 cm) the electric field has a vertical component and a horizontal component.

This indicates that the two spheres receive an equal distribution of the charge.

First off, we have:

Charge on sphere A

Sphere B: -q/2 charge

Sphere B is initially contacted by sphere C. Since the two spheres' combined charge was.

When two conducting spheres come into contact, the charge is divided between them, making their potential equal.

V₁ = V2 8 = 8/2

where Q stands for the charge and C for the sphere's capacitance. The capacitance is the same for identical spheres, hence the preceding equation becomes Q1 = Q2.

Sphere B is initially contacted by sphere C. Given that the two spheres' combined charge was

- q/2 + 0 = - q/2

Each sphere will have a charge after contact that is half of this value:

q B = q C = (-q/2) * (1/2) = (-q/4)

Sphere A (charge of +q) is then touched by sphere C (charge of -q / 4). The total charge is therefore -q/4 + q = q*3/4.

Since the charge is evenly distributed, each sphere will get half of it:

Q A = Q C = Q_ = 1/2 * (3/4 * Q) = Q_ =

The three spheres' ultimate charge will thus be spherical was

q + 0 = q

Each sphere will have a charge after contact that is half of this value:

Q A = Q C = Q/2 = 1/2 * Q

Sphere B (charge of -q/2) is then touched by sphere C (charge of q/2). Thus, the total charge is equal to -q/2 + q/2/2.

. Thus, the total charge is equal to -q/2 + q/2/2 = 0.

Each sphere will get half of this charge since the charge is distributed equally, which translates to a charge of zero:

q {B} = q {C} = 0

So the change in temperature can be calculated as: Q = mcΔT = (2 kg) * (4200 J/kg°C) * ΔT = 8400 * ΔT

ΔT = Q / mc = 10,000 J / (2 kg * 4200 J/kg°C) = 2.38°C

Therefore, the final temperature of the water is: 23°C + 2.38°C = 25.38°C

Assumptions:

The water is isolated and no heat is lost to the surroundings.The specific heat capacity of water is constant.The immersion heater is 100% efficient, meaning no energy is lost as heat to the surrounding.

What is the kinetic energy of a 10 kg object moving at 2. 0 ms?.

Answers

The object has a kinetic energy of 20 J.

The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. After the work is finished, energy is transferred to the item, which then moves at a new, constant speed.

The formula below can be used to determine the kinetic energy of a moving body: K.E = ½ × m × v²

kinetic energy (K.E) (J)

m = mass (kg) and v = speed (m/s).

The answer to this question is that the item has a mass of 10 kg and a velocity of 2.0 m/s.

K.E = ½ × 10 × 2²

K.E = 20J

A 10 kilogram object travelling at a speed of 2.0 m/s has a kinetic energy of 20 J.

What can auto salvage dealers use electromagnets for?

Answers

Electromagnets can be usefully employed by auto salvage to move scrap metal from one place to another place. Whenever the current is switched off the magnet loses its magnetism and the car falls back to the ground.

An electromagnet is a made coil that is associated with a ferromagnetic core. Whenever an electric current flows through the wire of the solenoid, it generates magnetic field similar to that of a magnet. Whenever the electromagnet is a solenoid which is wounded around a central iron core. The main advantage of an electromagnet over a permanent magnet is that we can quickly change the magnetic field by controlling the amount of electric current in the winding. The magnetic field which is created by an electromagnet is proportional to both the number of turns in the winding and the current in the wire.

Which statement best describes the gravitational force of an object? (1 point)
The farther away an object is, the greater its
ravitational force will be
The greater the object's mass, the less its gravitational force will be.
O The greater the object's mass and the closer It is, the greater itS gravitational force.
O The object only has gravitational force when it is on the surface of a massive body, such as Earth.

Answers

The greater the objects mass, and closer it is,the greater its gravitational force will be is the statement that best describe the gravitational force of an object.

According to the Newtons Law of Gravitation states that the gravitational force between two objects is directly proportional to the product of two  objects masses. And inversely proportional to the square of the distance between two objects.

F=G(m1*m2/r*r)

F= force

G= gravitational constant  

m1,m2= mass of object

r= distance between two masses.
