Explanation:
here we have mass(m);20 000N in kg will be 9.8kg
acceleration due to gravity (g): 10m/s
height (h) : 10m
so work done will be,
W=mgh
9.8x10x10
980joules
Answer:
The induced current in the coil at the time 2 s is 0.00263 A
Explanation:
The equation for induced emf is equal to:

Where
B = magnetic field
A = area
θ = angle

For t = 2 s

The induced current is:

Answer:
You have to calculate
Explanation:
Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work.
