The science behind how a refrigerator works is a novel area of study that physicists have continued to improve upon, delivering very efficient and smart refrigeration systems for homes and offices. In explaining the working […]
The water vapor in the atmosphere is important because it affects our comfort. Except in cold weather, we sweat continuously: the water in the sweat evaporates, draws its latent heat of evaporation from the skin, […]
The pressure of the atmosphere decreases with increasing height above the earth’s surface, because the thickness, and therefore the weight, of the belt of air above the observer decreases. The rate of fall in pressure […]
Magnetic Material: Steel is more suitable for permanent magnets, because it high coercivity meaning that it is not easily demagnetized by shaking. The fact that the remanence of iron is a little greater than that […]
If a diving springboard is bent and then allowed to vibrate freely, it oscillates with a frequency which is called its natural frequency. When a diver on the edge of the board begins to jump […]
Electrostatic shielding: The fact that there is no electric field inside a close conductor, when it contains no charged bodies, was demonstrated by Faraday in a spectacular manner. He made for himself a large wire […]
A ferromagnetic material has a very high value of susceptibility, χ, and hence of relative permeability, µr. The value of µr can be several thousands. Like a paramagnetic material, the magnetization is in the direction […]
