One end of the rope is vibrated to produce a wave with a wavelength of .25 m. The Frequency
of the wave is 5.0 Hz. What is the speed of the wave?

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Two polarizers are oriented at 24.0∘ to one another. light polarized at a 12.0-degree angle to each polarizer passes through both. what is the transmitted intensity (%)?
