Answer:

Potential energy refers to the stored up energy within an object, that builds up and can potentially be used to propel that object.

Explanation:

A famous example, would be water behind a dam. The rushing water fills up behind the dam, and since it's being held in one place, it will build up until of course the dam is either moved or lifted, and then all the water will be forced (due to all the energy that was being stored) down the rest of the stream.

I hope the explanation makes sense. If it doesn't, please let me know and I'll try to find another one for you :)

Potential energy is the an objects energy that is currently not being used but can be used. Example: A ball at the top of a hill is full of potential energy, and as soon as it begins rolling that becomes kinetic energy because it is in use. (Hard to explain but I hope this helps.)

Compare and contrast the health benefits and the amount of physical or mental energy needed between active leisure activities an
dolphi86 [110]
This is the answer "Some active leisure activities, such as yoga and running, require a great deal of physical energy, while other activities, like playing chess, require a substantial amount of mental energy. Passive leisure activities, such as watching TV or going to the movies, require little to no physical or mental energy. Because of the exertion of physical or mental energy, active leisure activities have more health benefits than passive leisure activities." hope it help you?:)

An average human weighs about 600 N
NemiM [27]

Answer:

The distance between them, x = 5809.47 m

Explanation:

Given,

The average weight of a human, w = 600 N

The charge carried by the humans, q = 1.5 C

If 600 N of force acts between two opposite charges, the distance between the charges can be derived from the Coulomb's laws of force,

                          <em>F=\frac{1}{4\pi\epsilon_{0}}\frac{qq}{x^{2}}</em>

Where,

                         \frac{1}{4\pi\epsilon_{0}} = 9 x 10⁹ N m² C⁻²

Therefore

                          x² = 9 x 10⁹ X 1.5² / 600

                              = 33750000

                           x = 5809.46 m

Hence, the distance between the humans should be, x = 5809.47 m

A lightbulb has a power of 100 W and is used for 4 hours. A microwave has a power of 1200 W and is used for 5 minutes. How much
ladessa [460]

Answer:

a. E=1440KJ

b. E=360KJ

c. E=1.8 J

Explanation:

I have the power (Watts) is expressed as Energy (Joules) / Time (seconds), also I have to1hour * \frac{60min}{1hour}*\frac{60s}{1min}\\1h=3600s

so, for the lightbulb

100W= \frac{Energy}{3600s*4}\\Energy=100W*14400s\\ E=1440000J =1440KJ

Analogously, for the microwave

1200W= \frac{Energy}{60s*5}\\Energy=1200W*300s\\ E=360000J =360KJ

Now, I have to express the efficiency as Heat energy / power * 100 so1.8= \frac{Heat Energy}{100W}*100\\Heat Energy=1.8J

Done
