Answer:
emf will also be 10 times less as compared to when it has fallen
Explanation:
We know, from faraday's law-
and
So, as the height increases the velocity with which it will cross the ring will also increase.
Given
Now, from
From equation a and b we see that velocity when dropped from is 10 times greater when height is 40
so, emf will also be 10 times less as compared to when it has fallen
Answer:
Explanation:
Acceleration is defined as the change in velocity divided by the time it took to produce such change. The formula then reads:
Where Vf is the final velocity of the object, (in our case 80 m/s)
Vi is the initial velocity of the object (in our case 0 m/s because the object was at rest)
and t is the time it took to change from the Vi to the Vf (in our case 0.05 seconds.
Therefore we have:
Notice that the units of acceleration in the SI system are (meters divided square seconds)
