Explanation:
Equation for Impact
FΔt = ΔP,
F = force
Δt = Impact of time
ΔP = Change in momentum
Car steering is engineered to fail in order to maximize the time of contact and hence reduce the initial impact and mitigate the damage incurred.
Road guard railing crumple on contact to maximize impact time and hence reduce impact intensity and mitigate damage.
Road safety containers are loaded with liquid or sand as they improve the period of impact.
The statement which best explains why nickel will reach the ground first is: C. The force of air resistance acts more strongly on the sheet of paper than on the nickel.
<h3>What is gravity?</h3>
Gravity can be defined as a force of attraction that controls the movement of objects and the planets such as Earth around the Sun.
<h3>The factors that affect gravity.</h3>
Some of the factors that affect the force of gravitational attraction that is acting on an object or a physical body include the following:
Generally, nickel will reach the ground first before a sheet of paper due to the effect of the force of air resistance because it would act more strongly on the sheet of paper than on the nickel.

A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around the Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure.
The answer is C. Mountains. I hope this helped!
100-25=75
speed=distance/time so time=distance/speed
75/15 =5 seconds
