Answer:
Permanent magnetism (of the steel)
make me brainliestt :))
Answer:
the average induced emf in the second winding is
Explanation:
The magnetic field inside the first solenoid is given by,
Where is the permeability of the free space
N is the number of turns of solenoid per unit length
I is the current in the solenoid
A is the cross-sectional area of the wire
Replacing we have,
Thus average emf induced in the second windigs is,
Therefore the average induced emf in the second winding is
Answer:
(a) V = 36 v
(b) V = 18v
Explanation:
Check the attached file for the explanation
Answer:
Inelastic collisions actually do conserve energy, but the loss of energy to heat and mechanical vibration is hard to calculate so the math equating energy before and energy after is hard to balance.
