The best explanation for the difference in time is: A. The difference in weight doesn't affect the time, but they are affected differently by air resistance.
<h3>What is weight?</h3>
Weight can be defined as the force acting on an object or a physical body due to the effect of gravity. Also, the weight of an object (body) is typically measured in Newton.
<h3>The factors that affect weight.</h3>
Some of the factors that affect the weight that is possessed by an object or a physical body include the following:
In conclusion, the weight possessed by the shoe and shirt has no effect on time but would be affected differently by air resistance.

The 48 and 47 are different atomic masses, this is caused by having a different number of neutrons.
The answer is 0.245N.
<h3>What is kinetic energy?</h3>
- A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force.
- Kinetic energy comes in five forms: radiant, thermal, acoustic, electrical, and mechanical.
- The energy of a body in motion, or kinetic energy (KE), is essentially the energy of all moving objects. Along with potential energy, which is the stored energy present in objects at rest, it is one of the two primary types of energy.
- Explain that a moving object's mass and speed are two factors that impact the amount of kinetic energy it will possess.
(b) 0.100
For the block on the left,
∑=
–0.308N+0.245N=(0.250kg)a
a=−0.252 if the force of static friction is not too large.
For the block on the right, ==0.490N. The maximum force of static friction would be larger, so no motion would begin, and the acceleration is zero

The answer is D. The input force is equal to the output force.
I just did test and got it right
Answer:
V = 2.8 m/s
Explanation:
It is given that,
Mass of falcon,
Mass of dove,
Initial velocity of falcon,
Initial velocity of dove,
When the falcon catches the dove, the momentum remains conserved. Using the formula for the conservation of momentum as :
V is the velocity after impact
V = 2.8 m/s
So, their velocity after the impact is 2.8 m/s. Hence, this is the required solution.
