Explanation:
From the question we are told that:
Turns Ratio i.e
Voltage
Primary current amplitude
Generally the equation for a Transformer is mathematically given by
Therefore
1) 2.17 s
The period of a mass-spring oscillating system is given by
where k is the spring constant and m is the mass attached to the spring. In this problem, we have
k = 25.1 N/m
m = 3.0 kg
Substituting into the equation, we find
2) 0.46 Hz
The frequency of the oscillating system is equal to the reciprocal of the period:
Therefore, by substituting T=2.17 s, we find:
3) 0.13 s
As before, the period of a mass-spring oscillating system is given by
where k is the spring constant and m is the mass attached to the spring. In this part of the problem, we have
k = 25.1 N/m
m = 11 g = 0.011 kg
Substituting into the equation, we find
4) 7.69 Hz
The frequency of the oscillating system is equal to the reciprocal of the period:
Therefore, by substituting T=0.13 s, we find:
5) 1.59 s
Again, the formula for the period of a mass-spring oscillating system is given by
In this part of the problem, we have
k = 25.1 N/m
m = 1.6 kg
Substituting into the equation, we find
