Question

A kid is trying to solve a problem and he has: `(13m/s^2*12m/s*21 kg)/(2000 A)=` State his answer with one unit?

Answer 1

`1.64` volts to the nearest third sig fig

Explanation:

Let's break down it down into steps:

`m/s^2` is acceleration

`kg` is mass

`F=ma`

`m/s` is velocity

`P=Fv`

So the top half can be simplified to power which is measured in watts.

So far we have the units of watts over amperes

`P=IV`

`P/I=V`

The singular unit of watts over amperes would be volts.

Now that we have the units, we can work out the problem giving us `1.64` volts.
