Answer:

Workdone in bringing a unit positive charge from low potential to higher potential against the electric field is electric potential energy.

Electric potential difference is yhe difference of potential energy at the terminals of battery or conductor eire attached to the battery.

Answer:b.20.8L

Explanation:

Since pressure is constant we can use the equation V1/T1 = V2/T2

(20/250)=(x/260)

5200=250x

X=20.8

A 750-kg automobile is moving at 26.2 m/s at a height of 5.00 m above the bottom of a hill when it runs out of gasoline. The car
Kisachek [45]

To solve this problem it is necessary to apply to the concepts related to energy conservation. For this purpose we will consider potential energy and kinetic energy as the energies linked to the body. The final kinetic energy is null since everything is converted into potential energy, therefore

Potential Energy can be defined as,

PE = mgh

Kinetic Energy can be defined as,

K= \frac{1}{2} mv^2

Now for Conservation of Energy,

KE_i+PE_i = PE_f

\frac{1}{2}mv_i^2+mgh_1 = mgh_2

\frac{1}{2} (750kg) (26.2m/s)^2 + (750)(9.8)(5) = (750)(9.8)h_2

h_2 = 40.0224m

Therefore the highets position the car reaches above the bottom of the hill is 40.02m

Describe the difference between potential and kinetic energy
chubhunter [2.5K]

Answer:

Explanation:

Kinetic energy involves motion so something that is not moving has zero kinetic energy.

Potential energy does not involve motion and is based on position in a field like gravity and magnetic.
