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:
The magnitude of the acceleration of the boy toward the girl is
Explanation:
It is given that,
Mass of the boy,
Mass of the girl,
The acceleration of the girl toward the boy is,
To find,
The acceleration of the boy toward the girl.
Solution,
Let is the magnitude of the acceleration of the boy toward the girl. We know that force acting on one object to other are equal in magnitude but opposite in direction. So,
So, the magnitude of the acceleration of the boy toward the girl is
