Answer: FM radio waves, AM radio waves, yellow light, micro waves
Explanation:
Answer:
ε₂ =2.63 V
Explanation:
given,
M = 0.0034 H
I (t) = I₀ sin (ωt)
I (t) = 5.4 sin (143 t)
magnitude of the induced emf in the second coil
ε₂ =
ε₂ =
for maximum emf
cos (143 t) = 1
ε₂ =
ε₂ =2.63 V
Answer:
it depends on how hard and fast he hit the ball a baseballs terminal velocity, a baseball can reach a velocity of around 95mph
Answer:
Explanation:
there is some magnetic field in between the space between the poles of a magnet. So, when a current carrying conductor is placed in a magnetic field, it experiences a force which is given by
F = B x i x l x Sinθ
where, B is the strength of magnetic field, i is the current in the conductor, l is the length of the conductor and θ is the angle between the length vector and the magnetic filed vector.
