In the following expressions:

V-volume

A-area

P-pressure

p(lowercase)-density

t-time

m-mass

v-velocity

g-acceleration due to gravity

I'm supposed to state whether the following equations are dimensionally correct or incorrect, using the above variables in terms [L,M,t], the MKS system..

1. m/t=(3/2)pV/t

2. PV=(1/2)mv

^{2}+mg(V/A)

Can ANYONE explain to me if these are dimensionally correct or not and why?
