Kinetic Energy in Joules
KE = ½mV²

plug in the numbers, first converting km/hr to m/s.

250 watts is the audio power rating of the amplifiers in the system, and has no relationship to 60 Hz AC power, which is probably more like 50-100 watts.

huh?

what does "creating dc voltage source to an ac voltage output" possibly mean? You need to learn english sentence structure.

light is DC, output of a solar panel is DC.

You can...

P = E²/R
.042 = E²/2200
E² = 92.4
E = 9.61 volts

If you have to have them tightened every month, then guess what, you have them tightened every month! But check with your dentist, you could probably go 1.5 months – 1.5 months, so that is only one...

v = ?(GM/R)
v = velocity
G = 6.673e-11 Nm²/kg²
M is mass of central body
R is radius of orbit

5800 = ?(6.673e-11*5.98e24/R)
solve for R
3.364e7 = 6.673e-11*5.98e24/R
R =...

drift velocity, and it is a matter of seconds, but it could be minutes or longer.

you can calculate it
drift velocity Vd
Vd = I / nqA
i is current
n is the number of charge carriers per...

look up audio filters.

you need a mike and an amplifier to convert the sound to a voltage. Then several audio bandpass filters to separate the different tones to different parts of the circuit....

because the force is at right angles to the motion.

you need the speed of the honda. If it is not moving:

Initial momentum = final momentum
3000V = 3800*8.5
V = 10.8 m/s

29.675 mhz ?? wow, that is 0.029675 Hz

it will have zero range!

Yes, if you are sailing directly away from the wind, you can't go faster than the wind. But on a broad reach, at about right angle to the wind, the wind exerts a constant force on the sail, which is...

it's a two way radio.

Or a CB radio or a cell phone or a satellite phone or a ham radio, all radios.

Radio transmitters send, radio receivers listen. Radio transceivers do both.

A lot.

You have to get it thru customs, and get it certified as passing all of the safety and pollution laws. And those vary from state to state.

I'd talk to the dealer you bought it from.

Radiation.

That is how the heat from the sun gets to us.

It uses electromagnetic waves in the IR (Infra Red) band and the visible band.
