Answer:
There are finally 4 rotations per second.
Explanation:
If a trapeze artist rotates once each second while sailing through the air, and contracts to reduce her rotational inertia to one fourth of what it was. We need to find the final angular velocity. It is a case of conservation of angular momentum such that :
Let 
, 
and 
So,
So, there are finally 4 rotations per second. Hence, this is the required solution.
Yes, that’s physically inactive. You should be moving your arms and legs if you’re going to be sitting down.
Answer:
If you are sitting in a chair right now there are two forces acting on you. The first is gravity which is what may make it difficult to stand up . The other is the force of the chair itself pushing up on you.

Answer:
Explanation:
The formula for centripetal acceleration is
and filling in:
and solving for r:
gives us that
r = 79.6 m
Here is the highly detailed, arcane, complex, technical form of Ohm's Law that is needed in order to answer this question ===> I = V / R .
Current = (voltage) / (resistance)
Current = (1.5 V) / (10 Ω)
<em>Current = 0.15 Ampere</em>
