All electromagnetic radiation ... all wavelengths, all frequencies ... has the
same speed, as long as you're measuring all through the same medium.
The speed is fastest in vacuum ... 299,792,458 meters per second. It's
slower than that in any material, and different in every material.
Newton's 2nd law of motion: (Honestly, if you don't
remember this by now, you're going to have problems.)
Force = (mass) x (acceleration).
= (60 kg) x (1.25 m/s²)
= 90 kg-m/s²
= 90 Newtons .
Answer:
the flywheel's average angular acceleration is -2.05 rad/s²
Explanation:
<u>Note:</u> counterclockwise is positive
clockwise is negative
Given;
initial angular velocity,
= 5.03 rev/s = 
final angular velocity,
= -2.63 rev/s = 
duration of the flywheel rotation, Δt = 23.5 s
The average acceleration of the flywheel is calculated as;

Therefore, the flywheel's average angular acceleration is -2.05 rad/s²
The neutron. As a neutron breaks apart the nucleus of a uranium atom, it causes a chain reaction releasing more neutrons. When we control this reaction we can harness the energy and produce nuclear power. When the reaction is left unchecked you get a immensely powerful release of energy, an atomic bomb.
