Answer:
Explanation:
Given
-- mass of tub
Required
Determine the amount of power needed
Power is calculated as thus:
Substitute values for Energy and Time
Divide by 1000 to convert to kW (kilowatt)
Answer:
v = 0.028 m/s
Explanation:
In this case you take into account that all the elastic potential of the box, when the spring is compressed is equal to the kinetic energy of the box before it hits the spring. That is:
(1)
m: mass of the box = 4.5kg
k: spring constant = 85N/m
x: compression of the spring = 6.5cm = 0.0065m
You solve the equation (1) for v:
(2)
Next, you replace the values of the parameters:
The velocity of the box when it hits the spring is 0.028m/s
It doesn't. We do.
We rotate in such a way that the sun looks like it is rising and falling, but it really isn't.
Answer: Geothermal energy is produced by the heat of Earth's molten interior. This energy is harnessed to generate electricity when water is injected deep underground and returns as steam (or hot water, which is later converted to steam) to drive a turbine on an electric power generator.
