The orbital speed of the material in the solar nebula at Pluto's average distance from the Sun is about 5 km/skm/s. What was the orbital speed of this material when it was 28,000 AUAU from the Sun (before it fell inward with the collapse of the nebula)? Use the law of conservation of angular momentum.

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.

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
