Answer:
1570 V
Explanation:
N = 100
diameter = 2 m
radius = 1 m
B = 5 tesla
initailly the angle between the area vector of the coil and the magnetic field is zero and then the angle becomes 180 degree.
t = 2 s
Let Φ be the initial magnetic flux.
Φ = B A Cos 0 = 5 x 3.14 x 1 x 1 x 1 = 15.7 Wb
Let Φ' be the final magnetic flux
Φ' = B A Cos 180 = - 5 x 3,14 x 1 x 1 x 1 = - 15.7 Wb
According to the law of electromagnetic induction, the induced emf developed is equal to the rate of change of magnetic flux linked with the coil.
Answer: it says that the magnitude of average velocity is always equal to average speed so therefore it would be the last option
Answer: The value of x is -6.
Explanation:
To calculate the value of 'x', we need to solve each function happening inthe equation.
The equation provided to us is 
To solve this, we will multiply 4x with 2 and then subtract the like terms and finally, we evaluate the value of 'x'.
Hence, the value of x will be -6.
When capacitors are in PARALLEL, they add up. (like resistors in series)
If you connect these four capacitors in parallel, the combination behaves like a single capacitor of (4 x 2.5) = 10 mF.
That's the greatest capacitance you can make with these four pieces.
Answer:
The maximum velocity is 0.377 m/s
