A windmill is a type of turbine that is used to capture the energy of moving air.
When a car is moving, this creates a difference in the relative velocity of the car as compared to the surrounding air. This creates a wind that presses on the windscreen. It doesn't actually matter, in terms of the amount of pressure, whether the car is not moving and the air is moving, or the car is moving and the air is not moving, what matters is only the difference in velocity between the car and the air.
the brakes on a bicycle when used turn kinetic energy into chemical energy.
how am i supposed to know...I ASKED YOU D:<
An electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body. It was the first electrical measuring instrument. The first electroscope, a pivoted needle called the versorium, was invented by British physician William Gilbert around 1600.[1] The pith-ball electroscope and the gold-leaf electroscope are two classical types of electroscope that are still used in physics education to demonstrate the principles of electrostatics. A type of electroscope is also used in the quartz fiber radiation dosimeter.Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force. The electric potential or voltage of an object equals its charge divided by its capacitance, so electroscopes can be regarded as crude voltmeters. The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are only used with high voltage sources such as static electricity and electrostatic machines. Electroscopes generally give only a rough, qualitative indication of the magnitude of the charge; an instrument that measures charge quantitatively is called an electrometer.Source : Wikipedia
A tonometer is the medical term for the instrument used to measure the pressure in the eye to detect glaucoma. The tonometer shoots a blast of air into the eye, directly into the pupil.A tonometer is used to measure eye pressure.
