Answer:
the answer is 2m
Explanation:
the formula to find the mechanical advantage of an inclined plane is
MA (mechanical advantage) = L (length of plane) / H (height)
for this problem we already know the MA and length. simply plug that into the formula and isolate H.... you'll end up finding the height >> 2m
To solve the problem we will simply perform equivalence between both expressions. We will proceed to place your units and develop your internal operations in case there is any. From there we will compare and look at its consistency
At the same time we have that
Therefore there is not have same units and both are not consistent and the correct answer is B.
Answer:
c
Explanation:
When a satellite is orbiting the earth , a constant force is being applied on it which means it must has acceleration. Also the direction of satellite is always being changed when it is orbitting to there is always change in the velocity vector which means acceleration.
You can view in the attached diagram to understand how the velocity is being changed.
