Unlike fireflies and glow worms, most objects don't make their own light. So how can you see what's around you?

Some of the standing waves in an organ pipe open at both ends have the following frequencies: 100 Hz, 200 Hz, 250 Hz, and 300 Hz. It is also known that there are no standing waves with frequencies between 250 Hz and 300 Hz.

Compare and contrast the processes of evaporation and condensation

During a space shuttle launch about 830,000 kg of fuel is burned in 8 min. the fuel provides the shuttle with a constant thrust, or forward force.

To push a certain box across a level floor at constant velocity requires that a horizontal force be applied to the box. The magnitude of this force is half as great as the vertical force required to lift the box.
