Answer:
The induced emf is
Explanation:
From the question we are told that
The radius of the circular loop is 
The intensity of the wave is 
The wavelength is 
Generally the intensity is mathematically represented as

Here
is the permeability of free space with value

B is the magnetic field which can be mathematically represented from the equation as

substituting values


The area is mathematically represented as

substituting values


The angular velocity is mathematically represented as

substituting values
Generally the induced emf is mathematically represented as

At maximum induced emf 
So

substituting values
1. Amperes, is the SI unit (also a fundamental unit) responsible for current.
2.
Δq over Δt technically
Rearrange for Δq
I x Δt = Δq
1.5mA x 5 = Δq
Δq = 0.0075
Divide this by the fundamental charge "e"
Electrons: 0.0075 / 1.60 x 10^-19
Electrons: 4.6875 x 10^16 or 4.7 x 10^16
3. So we know that the end resistances will be equal so:
ρ = RA/L
ρL = RA
ρL/A = R
Now we can set up two equations one for the resistance of the aluminum bar and one for the copper: Where 1 represents aluminum and 2 represents copper

We are looking for L2 so we can isolate using algebra to get:

If you fill in those values you get 0.0205
or 2.05 cm
Answer:
Mechanical waves are waves that require a medium. This means that they have to have some sort of matter to travel through. These waves travel when molecules in the medium collide with each other passing on energy. One example of a mechanical wave is sound.
It’s hard to perfectly measure the distance something travels, as well as the exact time it takes, making the results have some variation.
