Answer:I think the answer is 5.43 I don’t rlly know
Explanation:
Max ang. speed(u) = 18 rad/s
final ang. speed(v) = 0
ang. displacement(s) = 220 rad
ang. acceleration = (v^2 - u^2)/2s = -18^2 / 2*220 = -0.7364 rad/s^2
v = u +at
0 = 18 - 0.7364t
t = 18/0.7364
t = 24.44 seconds
Answer:
Radiation pressure
Explanation:
Radiation pressure is gotten from the light source. The radiation pressure has a set mass limit of 150 solar masses. Any mass from 150 solar masses or below supports the formation of the stars.
However when the mass exceeds 150 solar masses the force of gravity is unable to hold the masses together and the excess mass
Is usually blown away after which the required mass is then used in the formation.
The seven types of waves are radio waves, microwaves, infrared, visible, ultraviolet rays, x-rays and gamma rays.
The electromagnetic spectrum is a broad spectrum consisting of various waves. It contains very long radio waves to very short gamma rays. However, the human eye can detect only a small portion of this spectrum called as visible light.
The other waves that are invisible to the eye have their applications in various fields.
For example, radio waves have the longest waves on the spectrum and are said to have lowest energy. An MRI machine uses these waves to see tissues and bones up close.

P.E=0.0675 J
Explanation:
Elastic potential Energy=Force × distance of displacement
The formula to apply is;
P.E=1/2 ks²
where k is the spring constant given as; 1.5 *10^-2 N/m and s is the displacement
In this case,
s=3
P.E= 1/2 * 1.5 × 10^-2 ×3²
P.E=1.5×10^-2*4.5
P.E=0.0675 J
