Overloading of muscle is caused by subjecting the muscle to more stress than they are accustomed to. This is the technique used by body builders to build the muscle mass. When the muscle is continuously subjected to this added stress, it eventually adapts to this stress by producing new myofibrils (which makes up the muscle fibre). This added stress causes the muscle fibre to grow bigger and stronger in order to handle this additional stress subsequently.
We get heat on earth from the sun. Energy from the sun is transferred through space and through earths atmosphere to the earths surface. And since this warms the earth surface it creates heat.
surface wave is a wave that travels along the surface of a medium. The medium is the matter through which the wave travels. Ocean waves are the best-known examples of surface waves. They travel on the surface of the water between the ocean and the air.
