The figure(Figure 1) shows the angular-velocity-versus-time graph for a particle moving in a circle, starting from θ0=0 rad at t
=0s. Draw the angular-position-versus-time graph. Include an appropriate scale on both axes.

Answer:
As position is the product of velocity and time, the area under the velocity-time curve will be the position.
Between 2 and 4 s, the area increases linearly to 20(4) = 80
Between 4 and 6 s, the additional area is 0(2) = 0
Between 6 and 8 s the area increases linearly by -10(2) = -20
which is a decrease.

Answer:
(A) 64.7172 VOLT (B) 6.471 A
Explanation:
We have given number of turns in primary that is
And number of turns in secondary that is
Primary voltage
(a) We have to find the secondary voltage
For transformer we know that
(b) It is given that a resistance of 100 ohm is connected across secondary so current in secondary
