Explanation:
It is given that, a mass attached to a spring oscillates and completes 53 full cycles in 28 s. Frequency of the system is given by the number of oscillations or vibrations per second. Here, the frequency of this system is given by :
f = 1.89 Hertz
The relationship between the frequency and the time period of the spring is inverse i.e.
T = 0.52 seconds
Hence, this is the required solution.
Uniform velocity means no Net force and therefore no acceleration. Acceleration only happens when the velocity changes.
Answer:
b . Move the conductor near a magnet
Answer:
0.24T/s
Explanation:
This problem can be solved if use the Lenz's Law, that is
( 1 )
but this emf is for the ring:
and we can replace this value in ( 1 )
where we have taken the area of a circle and a radius of 70cm=0.07m. dB/dt is the ratio of change of the magnetic field. Hence the answer is 0.24T/s
I hope this is useful for you
