Question #d04ce

Answer 1

a. `d=(Pt)/F`

Explanation:

Let's plug the work equation given to us `W=Fd` into the power equation given to us `P = W/t`.

`P = (Fd)/t`

Now to get it into the forms that we see in the answers, we need to solve for `d`. So we divide both sides by `F` and multiply both sides by `t`.

`P/F = (Fd)/(tF)`
`P/F = d/t`
`(Pt)/F = (dt)/t`
`(Pt)/F = d`

Giving us the answer of a

Hope that helps!

Answer 2

Option (a).

Explanation:

`P=W/t,...(1) and, W=Fd.......(2).`

Subst.ing `W" from "(2)" in "(1), "we get, "P=(Fd)/t.`

`:. Pt=Fd...."[Cross Multiplication]"`

`:. (Pt)/F=d....."[Division by "F].`

Hence, (a) is the right option.
