Answer:

23,8eV

Explanation:

A=Uq=12 (V)* 2* 1,6*10^-19 (C)=3,84*10^-18 (J)= 23,8 (eV)

In the bedroom of your house you would like to run a 240 W toward, a 30 W alarm clock, a 720 W tanning bed, and four 60 W lights
erica [24]

Answer: current = 10.25A

Explanation:

Toward = 240w

Alarm clock = 30w

Tanning bed = 720w

4 60 watts bulb = 60 * 4 = 240w

Total power = 240 + 30 + 720 + 240 = 1230w

Voltage = 120v

Recall that Power = current * voltage

1230 = current * 120

current = 1230/120 = 10.25A

The point that represents maximum potential energy is W.

The point that represents potential energy at 0 joules is Z.

The point that represents potential energy at 50 percent is Y.

The point that represents maximum kinetic energy is X.

Potential energy is the energy held through an object because of its function relative to other items, stresses inside itself, its electric-powered fee, or different elements. potential energy is energy this is saved – or conserved - in an object or substance. This saved energy is based totally on the position, arrangement, or state of the object or substance.

Potential energy refers to the stored energy within an object that exists because of the item's role, country, or arrangement. Potential energy is the strength this is stored in an item because of its function relative to some 0 roles. An item possesses gravitational capability strength if it is located at a top above (or beneath) the zero top.
