Answer:
The magnitude of average emf is 9.813 mV.
Explanation:
Given that,
Number of turns = 25 turns
Diameter = 1.00 m
Magnetic field = 50.0μm
Time = 0.200 s
Angle = 180°
We need to calculate the area of the coil
Using formula of area
We need to calculate the average emf
Using formula of emf
Where, N = number of turns
A = Area
B = magnetic field
Put the value into the formula
Hence, The magnitude of average emf is 9.813 mV.
To work out kinetic energy, we use the following formula: KE = 0.5 x mv^2. So, 0.5 x 4 x 16^2 = 512 J

Q1
There are two categories of a wave. That is transverse and longitudinal waves. Transverse waves forms crests and troughs while longitudinal forms compressions and rarefaction as they travel. Rarefactions are regions where the wavelengths are longer than other regions.
Q2
As the ray of light moves from an optically less dense to a more dense region it bends towards the normal.
If the sound is bending away from the earth's surface, then the ground must be warmer than the air. As the sound travels it moves from optically dense medium to a less dense medium. For this reason it bends away from the normal. This can only happen when, B. air is cooler than the ground.
Answer:
move
Explanation:
i think that is it
as plates move large blocks of crust move along the faults
