If electromagnetic force were not intrinsically so much stronger than gravity, the hand of the strongest man would crumble under the weight of a feather! Indeed to be consistent, in that circumstance,we ourselves would crumble under our own weight !

Please explain the above paragraph in simple words .

Take angle of projection as theta.

a person aiming to reach the exactly opposite point on the bank of a stream is swimming with a speed of 0.5 m/s.at an angle of 120 degree with the direction of flow of water. find the speed of water in the stream.................

The law of conservation of the electric charge is explained by the classical physics.

The law of conservation of the electric charge is interpreted by the quantum physics.

The law of conservation of the electric charge is an experimentally verified law.

The law of conservation of the electric charge relates the quantum physics to the classical physics.

wht's the dimensional formula of viscosity..????

assuming that the critical velocity of a viscous liquid flowing through a capillary tube depends upon radius r of a tube,density of the tube and co-efficient of viscosity of the liquid. use the method of dimensions to obtain a relation between these quantities.

A drop of olive oil of radius 0.25mm spreads into a circular film of radius 10cm on the water surface. Estimate the molecular size of olive oil?

For example. when Johannes Kepler (1571-1630) examined the extensive data on planetary motion collected by Tycho Brahe (1546-1601), the planetary circular orbits in heliocentric theory (sun at the centre of the

solar system) imagined by Nicolas Copernicus (1473—1543) had to be replaced by elliptical orbits to fit the data better. Occasionally, however, the existing theory is simply unable to explain new observations. This causes a major upheaval in science. In the beginning of the twentieth century, it was realised that Newtonian mechanics, till then a very successful theory, could not explain some of the most basic features of atomic phenomena.

If velocity,time and force were chosen as basic quantities, find the dimensions of mass.
