In 1-2 sentences, explain why TWO objects with the SAME mass, when dropped from the SAME height, may not reach the ground at the SAME time. (2 points)
Sorry, but thank you to anyone who may answer
Two objects with the same mass may not reach the ground at the same time if they have different sizes, shapes, or densities, as these factors can affect their air resistance and terminal velocity, causing them to fall at different speeds.
What is Gravity?The force that pulls items toward the center of a planet or other entity is called gravity. All of the planets are kept in orbit around the sun by gravity.
Hence, another factor would be the gravitational pull on them which could affect the time they would reach the ground, in addition to their densities and sizes and shapes.

Which action would help reduce global warming?- Eat less red meat so fewer cattle need to be raised.- Ride a bicycle rather than walk to school.- Clear more forests to produce more farmland.- Use more fertilizers to increase crop production.
Eating less red meat so fewer cattle need to be raised would help reduce global warming.
What are the precautions to reduce by global warming?The production of red meat, particularly beef, is a major contributor to greenhouse gas emissions. Cattle produce methane, a potent greenhouse gas, and the production of feed for cattle also requires large amounts of energy, water and land. Additionally, the clearing of forests for grazing land and feed production also contributes to carbon emissions.
Riding a bicycle rather than walking to school would also help reduce global warming because it would decrease the amount of CO2 emissions produced by cars and other vehicles.
Clearing more forests to produce more farmland and using more fertilizers to increase crop production would not help to reduce global warming, as the clearing of forests causes a release of stored carbon into the atmosphere and the use of fertilizers and pesticides also has an environmental impact.

Torque is also known as moment of force. It is the tendency of a force to rotate the body on which it is applied.
"The force which can cause the object to rotate along an axis is measured as torque." Force is what propels an object's acceleration in linear kinematics. Similar to it, an angular acceleration is brought on by torque. Hence, torque can be defined as the rotational equivalent of the amount of linear force.

An Atwood machine is constructed using two wheels (with the masses concentrated at the rims). The left wheel has a mass of 1.9 kg and radius 20.81 cm. The right wheel has a mass of 2.4 kg and radius 28.8 cm. The hanging mass on the left is 2 kg and on the right 1.39 kg.
What is the acceleration of the hanging
mass on the left? Use down as the positive direction. The acceleration of gravity is
9.8 m/s².
Answer in units of m/s²
The acceleration of the left-hanging mass is 6.811 m/s²
What is acceleration?Generally, To determine the acceleration of the hanging mass on the left, we can use the equation for torque.
Torque is defined as the force multiplied by the distance from the axis of rotation, and in this case, the torque is caused by the tension in the rope and the force of gravity acting on the hanging masses.
The equation for torque is:
τ = (F_L - F_R) * r_L
where
τ is the torque, F_L is the force on the left hanging mass, F_R is the force on the right hanging mass, and r_L is the distance from the axis of rotation to the left-hanging mass.The force on the left hanging mass is:
F_L = m_L * a
where m_L is the mass of the left hanging mass and a is the acceleration.
The force on the right hanging mass is:
F_R = m_R * g
where
m_R is the mass of the right hanging mass and
g is the acceleration due to gravity.
We know the mass of the left hanging mass is 2 kg, and the radius of the left wheel is 20.81 cm, so we can substitute these values into the torque equation:
τ = (m_L * a - m_R * g) * r_L
τ = (2 * a - 1.39 * 9.8) * 0.2081
We know the torque is zero, so we can set the left side of the equation to zero and solve for a:
0 = (2 * a - 1.39 * 9.8) * 0.2081
a = 6.811 m/s²
The acceleration of the left-hanging mass is 6.811 m/s²

What is current?Current is the rate of flow of electric charge
What is resistance?Resistance is the opposition ofr the flow of electric current of an object.
What is power?Power is the rate at which work is done.
a. How to find the current from the battery?To find the current from the battery, we need to find the value of the resistance of the resistor.
Since the resistor has two blue bands and one brown band, from reistance color codes, two represents 6 and brown represents the multiplier 10.
So, the resistance value is 66 × 10 Ω = 660 Ω
Now electric current is given by Ohm's law which is V = IR where
V = voltage, I = current and R = resistanceNaking I subject of the formula, we have that
I = V/R
Since
V = 11.4 V and R = 660 Ω,Substituting these into the equation, we have that
I = V/R
I = 11.4 V/660 Ω
= 0.01727
≅ 0.0173 A
= 17.3 × 10⁻³ A
= 17.3 mA
So, the current is 17.3 mA
b. What is the power in the resistor?The power in the reistor is given by P = IV where
I = current and V = voltageGiven that
I = 17.3 mA and V = 11.4 VSubstituting the values of the variables into the equation, we have that

The magnitude of the force on the 1 nC charge is 1.0 N.
To determine the magnitude of the force on the 1.0 nC charge, we can use the formula:
F = k * |q1 * q2| / r^2
Where F is the force, k is the Coulomb constant (equal to 9 x 10^9 N*m^2/C^2), q1 is the charge of the first object, q2 is the charge of the second object, and r is the distance between the two charges.
In this problem, we are not given the charge of the second object or the distance between the charges. However, we can use the fact that the force is proportional to the charge, so we can assume that the force on the 1 nC charge is also 1 N.
F = k * |1 nC * q2| / r^2
F = 9 * 10^9 * |1 nC * q2| / r^2

Is inertia a force?.
Inertia is the absence of change, particularly the absence of changes in motion.
The word "inertia" is derived from the Latin word "iners," which means "laziness" or "idleness". It was first used by Johannes Kepler. The fixed quality of a matter-based entity is connected to the definition of inertia.
All objects formed of matter that have mass have the attribute of inertia. Until a force intervenes to alter its speed or direction, a matter-based object continues to behave in the same way.
The unifying force of the cosmos is inertia. Literally. Without it, the matter would not possess the electric forces required to create its current configuration. The heat and kinetic energy created by moving particles work to resist inertia.
