(i) Dimensions of velocity =[M0 L1 T−1] Here, a=0,b=1,c=−1 (ii) Dimensions of acceleration =[M0 L1 T−2] Here, a=0,b=1,c=−2 (iii) Dimensions of force =[M1 L1 T−2] Here, a=1,b=1,T=−2 (iv) Dimensions of pressure =[M1 L−1 T−2] ∴ Here, a=1, b=−1,c=−2 ∴ The physical quantity is pressure.
If the dimensions of a physical quantity are given by M^ a L^ b T^c, then the physical quantity will be
