Does volume affect potential energy
Andrej [43]

Answer:

No, the volume don't affect the potential energy.

Explanation:

The volume does not affect the potential energy, as this energy depends on the mass and elevation of the body relative to the reference point. This analysis can be easily seen in the equation expressing potential energy

E_{p} =m*g*h\\where:\\m=mass[kg]\\g=gravity[m/^2]\\h=elevation[m]

A crane does 62,500 joules of work to lift a boulder a distance of 25.0 meters. How much did the boulder weight
alukav5142 [94]
Work = (force) x (distance)

62,500 joules = (boulder's weight) x (25 meters)

Divide each side by (25 meters) :

Boulder's weight = (62,500 joules) / (25 meters) = <u>2,500 newtons</u>

That's about 562 pounds.

Intensity: Radiation of a single frequency reaches the upper atmosphere of the earth with an intensity of 1350 W/m2. What is the
sesenic [268]

Answer:

The right answer is "1010 V/m".

Explanation:

The given values are:

Intensity,

I=1350 \ W/m^2

c = 3.00\times 108 \ m/s

\mu_0= 4\pi\times 10^{-7} \ T.m/A

Now,

The electric field's maximum value will be:

=  \sqrt{2\times u\times c\times I}

On substituting the values in the above formula, we get

=  \sqrt{2\times 4\times \pi\times 10^{-7}\times 3\times 10^8\times 1350}

=  \sqrt{32400\times 3.14\times 10^{-7}\times 10^8}

=  1010 \ V/m
