Answer:
Power = 13.5744 kilowatts
Explanation:
Power is the rate at which work is done. ... Great power means a large amount of work or energy developed in a short time. For example, when a powerful car accelerates rapidly, it does a large amount of work and consumes a large amount of fuel in a short time.
Formula for power = work/time
= IVT/T
= IV
Where I is the current
And V is the voltage
The voltage V supply = 168 v
The current A supply = 80.8 A
Power = 80.8*168
Power = 13574.4 watts
Power = 13.5744 kilowatts
plzzz explain me your questions
Answer:
By pushing the pendulum Bob up so it moves faster
Explanation:
In pendulum physics the length of the pendulum Bob determines the speed of the clock. So since the grandfather's clock is slow it means the Bob is has moved down so to move it up you have to achieve this by adjusting the but upwards thereby making the clock move faster.
Answer:
The correct option is A. 18 V
Therefore,
Explanation:
Given:
Total Voltage,
V = 56 V,
Voltage drop
To Find:
(Assumed ,as it is not given clearly in the question)
Solution:
So in series combination total Voltage is given as
Substituting the values we get
Therefore,
At the release point, the ball has kinetic energy,
and at its maximum height it has potential and kinetic energy,
where 
is the maximum height attained above the release point.
The LoCoE tells us that we should have
