Answer:
Refractive motion is the impact of a light wave that travels from medium to medium in an angle away from normal, where the direction of light varies. Light is refracted when it crosses the air-to-glass interface and moves slower.

Answer:
V = (v1 + v2) / 2 = (8 + 6.5) / 2 = 7.25 m/s average speed
t = 7.2 / 7.25 = .993 sec time to cross patch
a = (v2 - v1) / t = (6.5 - 8) / .993 = -1.51 m/s^2 or 1.5 m/s^2
Answer:
<h2>760 m/s</h2>
Explanation:
The jet's speed or final velocity can be found by using the formula
<h3>v = u + at</h3>
where
v is the final velocity
u is the initial velocity
t is the time taken
a is the acceleration
From the question we have
v = 600 + 20(8)
= 600 + 160
We have the final answer as
<h3>760 m/s</h3>
Hope this helps you
The speed of waves are determined by the frequency of the push(wind). This really determines what the wave is being pushed by. If it were a Tsunami it would be by the frequency of the Tsunami if it were from the wind then the winds frequency would determine it's speed. Also the wavelength determines the speed because of the wight it has, but again something has to cause this wave to move.
Answer:
You can get w =Fxd 20Nx5m w=100N energy= w÷t 100N÷4s E=25J 3 you can apply 3J in one second
