How can a force be resolved into its perpendicular components?
How can a force be resolved into its perpendicular components? In two dimensions, a force can be resolved into two mutually perpendicular components whose vector sum is equal to the given force. The components are often taken to be parallel to the x- and y-axes. Let F be a force, of magnitude F with components […]
What is the function of the turbine in the power plant?
What is the function of the turbine in the power plant? The gas turbine is the engine at the heart of the power plant that produces electric current. A gas turbine is a combustion engine that can convert natural gas or other liquid fuels to mechanical energy. This energy then drives a generator that produces […]
What is load factor of motor?
What is load factor of motor? Load factor is an expression of how much energy was used in a time period, versus how much energy would have been used, if the power had been left on during a period of peak demand. It is a useful indicator for describing the consumption characteristics of electricity over […]

What is the formula to calculate monthly payments on a loan?
What is the difference between conduction convection radiation and evaporation?
What is the difference between conduction convection radiation and evaporation? Conduction transfers heat from one object to another through physical contact. Convection transfers heat to air or water. Radiation transfers heat via infrared radiation. Evaporation transfers heat as water changes state from a liquid to a gas. What is the difference between convection and conduction […]
