Power is a "measure of how quickly work is done."
Hope this helps!
Thanks!

Yes. If a downward force is created, it will be felt at the end of the rope as well.
The force of the throw is an applied force
moving through the air is drag
and the downward pull would be due to gravity
Answer:
15.32°
Explanation:
We have given the wavelength
Diffraction grating is 1460 lines per cm
So (as 1 m=100 cm )
For maximum diffraction
here m is order of diffraction
So
<u>Analysing the question:</u>
since the ball is thrown upwards, the gravity will be applied opposite to the motion of the ball
We are given:
acceleration due to gravity (a) =<em> -10 m/s²</em>
initial upward velocity (u) = <em>16.6 m/s</em>
final upward velocity (v) = <em>5.3 m/s</em>
distance between the friends (s) =<em> s m</em>
<em />
<em>Neglecting air resistance</em>
<em />
<u>Solving for the distance between the friends:</u>
from the first equation of motion
v = u + at
replacing the variables
5.3 = 16.6 + (-10)(t)
-10(t) = 5.2 - 16.6
-10 (t) = -11.3
t = 1.13 seconds
from the second equation of motion
s = ut + 1/2 at²
replacing the variables
s = (16.6)(1.13) + -5(1.13)²
s = 18.8 - 6.4
s = 12.4 m
Therefore, the 2 friends are 12.4 m apart
