I think it’s R=U/I = 120/5 = 24
Impulse=force*time
impluse=120N*2.0s
impluse=240 Ns
Answer:
0.25 v L
Explanation:
length of the bar = L
magnetic field, B = 0.25 T
Speed of bar = v
The formula for the motional emf is given by
e = B x v x L x Sinθ
Where, e be the induced emf, v be the speed, L be the length of the conductor, θ be the angle between the velocity vector and the length vector
Here, θ = 90 degree
So, e = B x v x L
e = 0.25 x v x L
e = 0.25 v L
Answer:
c, its axis is tilted
maybe
As it works its way around the sun, its tilted axis exposes different parts of earth.
C would be it because the roation of Earth on its axis doesn't have anything to do with the exposer of the revolution on its axis
