Answer:
c) heat
Explanation:
steam has more heat energy than boiling water due to its latent heat of vaporisation.
(a) At its maximum height, the ball's vertical velocity is 0. Recall that
Then at the maximum height , we have
(b) The time the ball spends in the air is twice the time it takes for the ball to reach its maximum height. The ball's vertical velocity is
and at its maximum height, so that
which would mean the ball spends a total of about 5.6 seconds in the air.
(c) The ball's horizontal position in the air is given by
so that after 5.6 seconds, it will have traversed a displacement of
Answer:
The output power is 2 kW
Explanation:
It is given that,
Number of turns in primary coil,
Number of turns in secondary coil,
Voltage of primary coil,
Current drawn from secondary coil,
We need to find the power output. It is equal to the product of voltage and current. Firstly, we will find the voltage of secondary coil as :
So, the power output is :
or
So, the output power is 2 kW. Hence, this is the required solution.
Explanation:
I think holding a flower pot. more energy will be needed
