The properties that change how we perceive light waves are the following:

The amplitude of the light wave changes the brightness of light relative to other light waves of the same wavelenghth.

The frequency of the light wave changes the color and the type of the light wave.

Review. A light spring of force constant 3.85 N/m is compressed by 8.00 cm and held between a 0.250-kg block on the left and a 0

The answer is 0.245N.

<h3>What is kinetic energy?</h3>

A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force.
Kinetic energy comes in five forms: radiant, thermal, acoustic, electrical, and mechanical.
The energy of a body in motion, or kinetic energy (KE), is essentially the energy of all moving objects. Along with potential energy, which is the stored energy present in objects at rest, it is one of the two primary types of energy.
Explain that a moving object's mass and speed are two factors that impact the amount of kinetic energy it will possess.

(b) 0.100

For the block on the left, $f_{k} =u_{k} n= 0.100(2.45N)=0.245N.$

∑ $F_{x}$ = $ma_{x}$

–0.308N+0.245N=(0.250kg)a

a=−0.252 $m/s^{2}$ if the force of static friction is not too large.

For the block on the right, $f_{k}$ = $u_{k} n$ =0.490N. The maximum force of static friction would be larger, so no motion would begin, and the acceleration is zero
