If `(1)/(f)=(1)/(u)+(1)/(v)`, then make v as the subject of the formula.

If (1)/(f)=(1)/(u)+(1)/(v) , then make v as the subject o the foormula. Also find v, if u=12 units and f=3 units

Make f as the subject of the formula

The focal length of a less is given by the formula (1)/(f)=(1)/(u)+(1)/(v) . Make f as the subject of the formula. if u=20cm and v=30, then find f. The following steps are involved in solving the above problem. Arrange them in sequential order. (A) Given (1)/(f)=(1)/(u)+(1)/(v) (B) rArr f=(uv)/(u+v) (C) f=(20xx30)/(20+30)=(600)/(50)=12 cm. (D) rArr (1)/(f)=(v+u)/(uv)

If (1)/(x)=(1)/(y)=(1)/(z)+(1)/(w) , then make w as te subject of the formula.

If S=(a)/(1-r) , then make r as the subject of the formula.

In v^(2)-u^(2)=2as , make a as the subject of the formula.
