An object, 5 cm high, is placed on the principal axis of a diverging lens of focal length 20 cm. The object is 30 cm from the lens. Use a scaled diagram to locate the image formed by the lens.

The transfer of heat through the movement of a gas or liquid a. convection b. conduction c. radiation

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

While standing outdoors one evening, you are exposed to the following four types of electromagnetic radiation: yellow light from a sodium street lamp, radio waves from an am radio station, radio waves from an fm radio station, and microwaves from an antenna of a communications system. rank these type of waves in terms of increasing photon energy.
