Answer:
2.5
That is my guess sorry if i get it wrong.
Answer:
The strength of the magnetic field is 0.08 mT
Explanation:
Given:
Length of rod m
Velocity of rod
Induced emf V
According to the faraday's law
We know that the induced emf of rod is given by,
Where magnetic field
For finding the magnetic field,
mT
Therefore, the strength of the magnetic field is 0.08 mT
Answer:
Force in the rocket will be 4166.64 N
Explanation:
We have given mass of the rocket m = 3 kg
Rocket acquires a speed of 50 m sec so final speed v = 50 m/sec
Initial speed u = 0 m/sec
Distance traveled s = 90 cm = 0.9 m
From third equation of motion we know that
From newton's law we F = ma
So force will be
So force in the rocket will be 4166.64 N
