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.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
