To solve these problems first draw the free body diagram:
Answer:
Explanation:
Thermal expansion is where materials expand while being heated, causing them to take up more space. Some materials expand more than others. But this all happens due to the motion of tiny little molecules. Temperature is the average kinetic energy of the molecules in a substance.
Thermal expansion is an important consideration for engineering because different materials exhibit changes in size when exposed to heat. Thus, affecting length, width, surface area, volume, shape etc
Explanation:
electricity is the flow of electrical power or charge
The frequency of any repeating event is the number of times it happens in some specified period of time.
The frequency of a wave is the number of cycles, wiggles, compressions etc. that occur in a given time, usually one second.
