For physical quantity z, given by expression `z=(gh^(1"/"2)I)/(mx^3)`, write the expression for relative error in it.

In the expression A = (xy^(3))/(Z^(2)) the percentage error is given by

Solve the expression (2x + 3y - 4z ) ^(2).

A physical quantity P is given by P=(A^(3)B^((1)/(2)))/(C^(-4)D^((3)/(2)) The quantity which brings in the maximum percentage error in P is,(Fractional error in A,B,C and D are equal

A physical quantity z depends of four obserbles a, b, c and d, as z = (a^2b^(2/3))/(sqrtc d^3) . The percentages of error in the measurement of a,b,c and d are 2%, 1.5%, 4% and 2.5% respectively. The peracentage of error in z is :

If the dimensions of a physical quantity are given by M^(x) L^(y) T^(z) , then physical quantity may be

Name the physical quantity used to express the amount of water vapour presentin air.

A physical quantity rho is calculated by using the formula rho =(1)/(10)(xy^(2))/(z^(1//3)) , where x, y and z are experimentally measured quantities. If the fractional error in the measurement of x, y and z are 2%, 1% and 3% , respectively, then the maximum fractional error in the calculation of rho is
