Answer:
Part a)

Part B)

Part C)

Explanation:
Part a)
Magnetic field due to a long ideal solenoid is given by

n = number of turns per unit length



now we know that magnetic field due to solenoid is


Now magnetic flux due to this magnetic field is given by




Part B)
Now for mutual inductance we know that




now we have


Part C)
As we know that induced EMF is given as



Answer:
x=0.53
Explanation:
Using Gauss law the field is uniform so
E=ζ/ε
Charge densities ⇒ζ=1.
ε=8.85

Force of charge is


So finally knowing the acceleration and the time the distance can be find using equation of uniform motion

Answer:
Explanation:
Energy = volt x charge
= 12 x 750000 J
= 9000,000 J
Latent heat of vaporisation
= 2260000 J / kg
kg of water vaporised
= 9000,000 / 2260000
= 3.982 kg .
Answer:
The gravitational acceleration is same for all objects.
a = b = c = d
Explanation:
Acceleration due to gravity or gravitational acceleration is the force exerted by Earth on unit mass of an object.
Acceleration due to gravity doesn't depend on the height of the object when the height is object is near to the surface of the Earth. Only when the height is comparable to the radius of the Earth, the value of gravitational acceleration changes.
But for the objects here, the gravitational acceleration is independent of the mass or height of the objects and has a constant value of 9.8 m/s².
Therefore, the gravitational acceleration of all the objects is same.
If 'a', 'b', 'c', and 'd' represent gravitational accelerations of objects 'a', 'b', 'c', and 'd' respectively, then a = b = c = d.
They would be able to jump higher with less effort the ball would weigh less meaning it could be dribbled with little to no effort there would also be the fact that your running would be effected.your legs would come off the ground if only for an inch or two allowing you to travel faster but with less control
