Answer:
The work done by the worker on the crate is 4830 J.
Explanation:
Given that,
Force = 1080 N
Horizontal force = 345 N
Distance d = 14 m
Coefficient of friction = 0.22
We need to calculate the work done
Using formula of work done
F = force
d = distance
Put the value into the formula
Hence, The work done by the worker on the crate is 4830 J.
Based on the mass per unit length and the tension, the speed that the wave travels on this string is 519.615 m/s.
<h3>What is the speed?</h3><h3 />
The speed that the wave travels can be found as:
Velocity² = Tension / Mass per length
Solving gives:
Velocity² = 1,350 / 0.005
Velocity² = 270,000
Velocity = √270,000
= 519.615 m/s

So in a fluorescent light bulb the mercury atoms release the UV light. This UV light is absorbed by the phosphorous powder coating inside and this releases the visible light.
So your answer is phosphorous powder.
