Answer:
The angular acceleration is 10.10 rad/s².
Explanation:
Given that,
Mass of sphere =220 g
Diameter = 4.50 cm
Friction force = 0.0200 N
Suppose we need to find its angular acceleration.
We need to calculate the angular acceleration
Using formula of torque


Here, I = moment of inertia of sphere


Put the value into the formula


Hence, The angular acceleration is 10.10 rad/s².

Answer:
11060M Joules, where M is the mass of the diver in kg
Explanation:
Mass of the skydiver missing, we're assuming it's M.
It's total energy is the sum of the contribution of his kinetic energy (K)- since he's moving at 50 m/s, and it's potential energy (U), since he's subject to earth gravity.
Energy is the sum of the two, so 
Answer:
Word for the first blank: gravity
Word for the second blank: matter
Explanation:
The only way debris from the impact with Earth can be held close to Earth is due to a force. The only force that could be acting from Earth is "the force of gravity".
The gravitational pull of this new object being formed, increases proportional to its mass as more and more "matter" accumulates. And the accretion process is now on its way.
Answer:
Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
