Let us consider an equation `(1)/(2)mv^(2)=mgh`
Where m is the mass of the body. V its velocity , g is the acceleration due to gravity and h is the height . Check whether this equation is dimensionally correct.

Check whether the following equation is dimensionally correct 1/2mv^2=mgh

Check whether the equation mv^2=mgh is dimensionally correct or not.

The value of acceleration due to gravity is maximum at the ………….. (1)poles (2)equator (3)centre of the earth

Earth can be treated as a sphere of radius R and mass M. The acceleration due to gravity at Earth's surface is g. If we move from equator to pole, the value of g.

A company manufacturing PVC pipes claims in an advertisement that the volume of water flowing out through the pipe in a given time is as per the equation V=KA^2ut where A is the area of cross section of the pipe, u is the speed of flow, t is the time and K is a dimensionless constant. Check the equation and state whether the claimis correct.
