The first one it's very windy today and will rain later.
A= v²/R
a = 12²/30 =4.8 m/s²

Answer:
The magnitude of the voltage is and the direction of the current is clockwise.
Explanation:
Given that,
Number of turns = 9
Magnetic field = 0.5 T
Diameter = 3 cm
Time t = 0.14 s
We need to calculate the flux
Using formula of flux
Put the value into the formula
We need to calculate the emf
Using formula of emf
Negative sign shows the direction of current.
Hence, The magnitude of the voltage is and the direction of the current is clockwise.
Answer:60 rev/min
Explanation:
Given
angular speed of first shaft
Moment of inertia of second shaft is seven times times the rotational speed of the first i.e. If I is the moment of inertia of first wheel so moment of inertia of second is 7 I
As there is no external torque therefore angular momentum is conserved
