The work done by Nick as he raises the given mass over the given distance is approximately 2 Joules.
Given the data in the question:
- Mass raised;

- Distance covered;

Work done; 
First we calculate the force used to raise the mass to the given distance.
Since the movement was vertical, the force must over come the mass and the pull of gravity (
).
Using Newton's second law of Motion;

We substitute our values into the equation

Now, we determine the work done by Nick.
Work done is simply the energy transferred from one store to another.
It is expressed as;

So we substitute our values into the equation

Therefore, the work done by Nick as he raises the given mass over the given distance is approximately 2 Joules.

Y = v0t + 1/2gt^2.
v0 is 0 as it is at rest initially. So now we have y=1/2gt^2 so 60=1/2(9.8)t^2 and we must solve for t. t= about 3.5 seconds. Since the acceleration is 9.8 m/s^2 we do 9.8 m/s^2 times 3.5 seconds to get 34.3 m/s.
You would expect a thermal conductor to have low specific heat capacity, so it can hold more heat at a given time and transfer it.
Answer:
the lowest frequency is 
Explanation:
In the question it is given that wavelength(L) in the range of 200μm to 400μm.
let ν be frequency of wave v velocity = 3\times 10^8
velocity v= Lν
therefore ν=
frequency ν be lopwest when L will be heighest
ν(lowest)=
ν=
