Answer:
A
Explanation:
If you do B, the wagon slows down due to friction
If you do C, it would slow down the wagon by half
If you do D, it would slow it down, due to there being more weight but same force.
A. the gas particles move faster and collide more frequently, which causes an increase in pressure.
Increasing temperature increases the energy of the gas, which causes the kinetic energy of the molecules to increase.
F = ma
6.25 N = 0.4 kg · a
a = (6.25/0.4) m/s² since N=kg·m/s²
a = 15.625 m/s²
The answer is c) 15.6 m/s²
(Note that the mass of the soccer player is irrelevant.)
Answer:
Velocity
Explanation:
Speed does not have a direction, Acceleration means that it is speeding up and not at a constant 15m/h, so the answer is B.
potential, kinetic, elastc energies
