The movement of the waves themselves
Answer:
a. The speed is 2.39 m/s
b. The acceleration of the block is 10.2
Explanation:
First, we have to do the energy balance where we consider two states, the first where the spring remains still and the second when it is stretched 0.400m:
Δx=
W_{ext}=20.4 Nm

To determine, the acceleration we solve the following equation for a:

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.
Explanation:
modern quantum mechanics explains these periodic trends in properties in terms of electron shells. the filling of each shell corresponds to a row in the table
