Explanation:
The moon is the earth satellite and it orbits our blue planet. Earth, moon and mercury are all rock materials in the solar system. They are all made up of dense silicate balls of rocks.
- The Earth and Mercury are made up of silicate minerals and some iron core but the moon is predominant made up of silicate balls.
- The earth has liquid water on it's surface but the moon has no liquid water.
- The earth is an active planet in terms of tectonic activity. The moon is not active tectonically.

Answer: coefficient of static friction
= 0.31
Explanation: Since they negotiate the curve without skidding, the frictional force (F1) equals the centripetal force (F2).
F1= uN
F2 = M*(v²/r)
M is the combined mass 450kg
V is the velocity 18m/s
r is the radius 106m
N is the normal reaction 4410N
u is the coefficient of static friction
Making u subject of the formula we have that,
u = {450*(18²/106)} /4410
=1375.47/4410
=0.31
NOTE: coefficient of friction is dimensionless. It as no Unit.
Many ways, but some of the most famous are kicks (side, back, front, snap) or a smash.
Hope it helped! :)
The triangle <span>in the first law of thermodynamics, represents energy that moves from a hot object to a cooler object.</span>
In fact, the force Rahul exerts on Earth corresponds to the force of gravity. But Rahul's weight is, in fact, the force of gravity exerted by the Earth on Rahul, and these two forces correspond to the action-reaction pair of Newton's third law, which states that the two forces are equal.
