pasar las siguientes frecuencias medidas en r. p.m a sg∧-1 .830 r. p.m .4500 r. p.m .720 r. p.m .3832 r. p.m URGENTE PORFAVOR¡¡¡¡¡

The frequencies are 13.8 Hz, 75 Hz, 12 Hz and 63.8 Hz.

Explanation:

Given that,

The frequency in r.p.m

Suppose, we find the frequency in hz.

We know that,

One r.p.m is equal to the one divided by 60 Hz.

We need to calculate the frequency in Hz

Using formula for frequency in Hz

For f₁,

For f₂,

For f₃,

For f₄,

Hence, The frequencies are 13.8 Hz, 75 Hz, 12 Hz and 63.8 Hz.

photocells convert light energy to electricity

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
