The kinetic energy of the ejecta from a supernova explosion is about 10^44 joules. use the formula for kinetic energy to determine the typical speed at which matter is ejected from a supernova with a mass of 10 m sun. compare that speed with the sun's orbital speed around our galaxy. based on your comparison, do you think the galaxy's gravity would be strong enough to retain the supernova debris if there were no interstellar medium to slow it down? explain

What sort of waves exhibit the doppler effect?

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.

Which change would make the diagram correct?
