Answer:
Explanation:
Index of refraction:
where 
is the refractive index, 
is the speed of light in vacuum and 
is the speed of light in medium.
The speed of light in vacuum is 
Speed of light in medium is 
Thus,
Index of refraction of this substance through yellow light is
Answer:
Explanation:
Given:
Workdone by the system, Win = 580 J
Workdone consumed, W = 150 J
Heat loss, Wout = Win - W
= 580 - 150
= 430 J
Heat lost by the coils of the refrigerator to the kitchen = 430 J.
At the beginning of a basketball game, a referee tosses the ball straight
up with a speed of 4.6 m/s. a player cannot touch the ball until after it reaches its maximum height and begins to fall down. what is the minimum time that a player must wait before touching the ball? s

Answer:
<h3>The answer is 336 kgm/s</h3>
Explanation:
The momentum of an object can be found by using the formula
<h3>momentum = mass × velocity</h3>
From the question
mass = 4 kg
velocity = 84 m/s
We have
momentum = 4 × 84
We have the final answer as
<h3>336 kgm/s</h3>
Hope this helps you
Answer:
divide the distance by the time and get average velocity in units of s. the detection to the left
