Can you give more description ??
To know where they’re heading to
Answer:

Explanation:
As we know that the wheel is rotated at constant angular speed
so here we can say that the angular speed is given as



now the moment of inertia of all passengers is given as


now work done by machine must be equal to kinetic energy of the system
so we will have



Answer:
Rate of magnetic field is 15923.668 T/sec
Explanation:
We have given radius of loop conductor r = 2 mm = 0.002 m
Induced emf = 2 volt
As the magnetic field and plane are perpendicular to each other so angle between magnetic field and area is 0°
Cross sectional area of the conductor is equal to 

Induced emf is given by
