Answer:
Induced emf,
Explanation:
The varying magnetic field with time t is given by according to equation as :
Where
are constant
Let is the emf induced in the loop as a function of time. We know that the rate of change of magnetic flux is equal to the induced emf as:
So, the induced emf in the loop as a function of time is . Hence, this is the required solution.
The frequency of a simple harmonic oscillator such as a spring-mass system is given by
where
k is the spring constant
m is the mass attached to the spring.
Re-arranging the formula, we get:
and since we know the constant of the spring:
and the frequency of oscillation:
f=1.00 Hz
we can find the value of the mass attached to it:
where
k is the spring constant
m is the mass attached to the spring.
Re-arranging the formula, we get:
and since we know the constant of the spring:
and the frequency of oscillation:
f=1.00 Hz
we can find the value of the mass attached to it:
