The attraction between water molecules creates tension and a very delicate membrane. Water striders walk […]
Why does magnetic force act from a distance?
Why is the energy of an electron quantized?
Why is the energy of an electron quantized? This means energy is quantized. When you supply energy to an atom, the electrons inside absorb that energy and jump to higher energy levels. More the energy supplied, more excited the electrons get and eventually it is possible to separate the electrons from the force of the […]
