Answer:
Explanation:
Total rotational kinetic energy =
(Here fly wheel may have translational kinetic energy but we ignore here)
Angular speed = 3000 revolutions per minute
Angular speed = revolutions per second
Thus , Kinetic energy =
=
The sun's energy influences climate in various ways. For example the latitudes at the equator receive more energy from the sun and therefore have warmer temperatures, On the other hand the sun's energy influences precipitation in a climate by driving the water cycle which determines precipitation.The sun is what makes the water cycle take place. That is the sun provides energy or heat to the earth; the heat causes liquid and frozen water to evaporate into water vapor gas, which rises high in the sky to form clouds ( precipitation), that in turn give us rain
Answer:
true
Explanation:
the wavelength of AM radio is 10 m whereas FM has 1 m
Answer:
6000JOules
Explanation:
My friend this is quite easy.
There is an equation.
The energy is also presumed as heat.
To calculate the heat in a circuit or the energy the equation is H=I(square) RT
Heat= square of current x resistance x time
Here I=5a.
R=2 ohm
T=120s
H= 5x5x2x120=6000J
I hope this satisfies you.
If you have any questions ask me.
I hope u will follow me and make this the brainliest answer.

Your moving air in a vacuum cleaner, there is no central "vaccum". a series of fans move air, the moving air pushes the dirt until it is caught by a filter medium which the air is small enough to get through but the dirt is not. The air is then expelled from the device.
I guess you could use pistons to move the air as well, but either way your compressing air not pulling air away.
