What is the doppler effect?

The Doppler effect is caused when waves (such as light or sound waves) are emitted from a moving source which causes an increase or decrease in the wavelength of the emitted wave. This increase or decrease d...

As a student rubs his feet along the carpet in his living room, he becomes charged. After this he places his hand on a metal radiator and receives an electric shock. Explain what charge the student obtains, why, and why he receives a shock.

As the student rubs his feet on the carpet, negatively charged electrons are transferred from the carpet to his feet. This gives the student AS A WHOLE a net negative charge. The radiator is made from metal....

Write the equations of motion for constant acceleration and describe each term involved. Explain how to apply these equations of motion to calculate the horizontal and vertical components of a projectile moving under the force of gravity only.

The equations of motion for constant acceleration are obtained from Newton's laws of motion. They are sometimes known as the SUVAT equations and can be used to calculate components of a projectile's motion b...

Houses lose majority of their energy through the roof and windows. State the three methods of energy transfer. For the roof and windows respectively, describe one adaptation that could be made to improve their efficiency and explain their method.

Conduction, Convection, Radiation Roof: Insulation. Material reduces conduction as it is a greater inductor of heat than air. Material reduces convection currents as the air gaps are now too small for a conv...
