Question

Make K the subject of the formula

`t = \frac{mu {}^(2) }{k} - 5mg`
​

Answer 1

To make K the subject of the formula, we'll isolate K on one side of the equation:

t = (mu^2) / K - 5mg

First, add 5mg to both sides of the equation to isolate the (mu^2) / K term:

t + 5mg = (mu^2) / K

Now, to make K the subject, take the reciprocal of both sides (invert both sides):

1 / (t + 5mg) = K / (mu^2)

Now, isolate K:

K = (mu^2) / (t + 5mg)

So, K is the subject of the formula.

Answer 2

Explanation:

`t = (mu^(2) )/(k) -5mg\\kt = mu^(2) -5mg\\k = (mu^(2) -5mg)/(t)`

To make k subject of the fomula :

Step 1 : cross multiply

Step 2 : Divide both side of the equation to isolate k
