Which apple has the greatest potential energy?

Physics

fiasKO [112]3 years ago

Answer: Apple at point D

Explanation:

Potential energy is the energy possessed by an object by virtue of its position.

P.E=m\times g\times h

m= mass of object

g = acceleration due to gravity = 10ms^{-2}

h = height of an object  

Thus as can be seen from the relation, potential energy is directly proportional to the height of an object, the apple with maximum height, at point D will have maximum potential energy.

D. Because as height increases, so does the potential energy.

Setler [38]

Answer:

0.366×10^{-3} / s

Explanation:

θ = θmax e^{-bt/2m}

Given that

             θ = 5.50°

             θmax = 15.0°

So that we have

                ln (θ / θmax) = -bt /2m

            = - ln(5.50°/ 15.0°) / 1000s = b /2m

             = b / 2m = 0.366×10^{-3} / s

The Palo Verde nuclear power generator of Arizona has three reactors that have a combined generating capacity of 3.937×109 W . H
den301095 [7]

Answer:

t = 2.68 x 10¹⁴ years

Explanation:

First we need to find the amount of energy that Sun produce in one day.

Energy = Power * Time

Energy of Sun in 1 day = (3.839 x 10²⁶ W)(1 day)(24 hr/1 day)(3600 s/ 1 hr)

Energy of Sun in 1 day = 3.32 x 10³¹ J

Now, the time required by the nuclear power generator, in years, will be:

Energy of power generator = Energy Sun in 1 day = 3.32 x 10³¹ J

3.32 x 10³¹ J = Power * Time

3.32 x 10³¹ J = (3.937 x 10⁹ W)(t years)(365 days/1 year)(24 hr/1 day)(3600 s/ 1 hr)

t = 3.32 x 10³¹ /1.24 x 10¹⁷

<u>t = 2.68 x 10¹⁴ years</u>

2. Which state of matter—solid, liquid, or gas—is the best at conducting heat? Why?
Digiron [165]

Answer:

Best at conductioning heat- Solid

Explanation:

<u><em>In order for heat to conduct it has to pass from particle to particle.</em></u>

A solid has particles closely compacted so the heat is able to tranfer quickly from particle to particle.

A liquid has isn't as compacted it actually has enough space to slide over each other

A gas has very far apart particles and takes heat longer to transfer from one particle to another.
