Explanation:
The gravitational pull will reduce, because the moon is moving further away from the centre of the earth. In other words, the further an object is from the centre of the earth, the weaker the gravitational pull that will be exerted on it.
Answer:
Explanation:
mass of coffee filter, m = 1.4 h
height, h = 4 m
velocity, v = 0.5 m/s
The energy conservation
Potential energy of filter = kinetic energy of filter + energy gained by the air molecules
m x g x h = 0.5 x mv² + energy gained by the air molecules
0.0014 x 9.8 x 4 = 0.5 x 0.0014 x 0.5 x 0.5 + Energy gained by the air molecules
Energy gained by the air molecules = 0.05488 - 0.00000175
= 0.054878 J
