1.

Rearrange the equation ρ = mv\rho\ =\ \frac{m}{v}  and make  mm  as the subject.

a)

 ρm = v\rho m\ =\ v  

b)

 m = ρvm\ =\ \rho v  

c)

 m = ρvm\ =\ \frac{\rho}{v}  

d)

 v = mρv\ =\ m\rho  

2.

Make  PP  the subject of the equation x(1+P)2 = 4xx\left(1+P\right)^2\ =\ \frac{4}{x} 

a)

 1+P = 2x21+P\ =\ \sqrt{\frac{2}{x^2}}  

b)

 P = 4x2  1P\ =\ \sqrt{\frac{4}{x^2}}\ -\ 1  

c)

 P = 2x  1P\ =\ \sqrt{\frac{2}{x}\ -\ 1}  

d)

 P = 2x  1P\ =\ \frac{2}{x}\ -\ 1  

3.

Given equation Ek  = 12mv2E_{k\ }\ =\ \frac{1}{2}mv^2 . Make  vv  as the subject of the equation 

a)

 v2 = Ek12mv^2\ =\ \frac{E_k}{\frac{1}{2}m}  

b)

 v2 = Ek12mv^2\ =\ \sqrt{\frac{E_k}{\frac{1}{2}m}}  

c)

 v = Ek12mv\ =\ \sqrt{\frac{E_k}{\frac{1}{2}m}}  

d)

 v = Ek12mv\ =\ \frac{E_k}{\frac{1}{2}m}  

4.

Make  VV  as the subject of the equation PV = nRTPV\ =\ nRT  

a)

 V = nRTPV\ =\ \frac{nRT}{P}  

b)

 V = nRTPV\ =\ nRTP  

c)

 V =PnRTV\ =\frac{P}{nRT}  

d)

 V =nRT +PV\ =nRT\ +P  

5.
