Answer: To every action there is an equal and opposite reaction. So as the defensive player collides with the receiver it feels an equal and opposite impact also.
Newton Third law of Motion
Explanation:
Answer:
Explanation:
The hand throwing ball moves on a circular path having radius r = .55 m
mass of ball m = .19 kg
velocity v = 70 mph
= 70 x 1600 / 60 x 60
= 31.11 m /s
centripetal force
= mv² / r
= .19 x 31.11² / .55
= 334.34 N
I think the answer is b. compaction
Answer:
Gravitational potential energy
Explanation:
Gravitational potential energy is the type of energy an object has due to its position in a gravitational field. Water behind a dam possesses gravitational potential energy due to it being at a higher level than the water on the other side of the dam. When the water falls the gravitational potential energy is converted to kinetic energy, leading to the turning of the turbines to generate electricity.
