Answer:Net Force is zero
Explanation:
Given
Car is moving to the left with constant velocity i.e. net force on the car is zero
because change in velocity with respect to time is acceleration thus force is also zero because net acceleration is zero
Mathematically
acceleration
as velocity is constant therefore
thus a=0 , F=0
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.
