Some students fire a rocket of mass 0.150kg into the air. if at the top of it's flight it has a gravitational potential energy of 150j, what height did it reach?

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?

What happens to the electrostatic force between two charged particles if the distance between them is doubled?

Explain how waste energy is produced when an inefficient lightbulb converts electrical energy into radiant energy.
