Protons having a kinetic energy of 4.70 MeV are moving in the positive x-direction and enter a magnetic field of 0.0650 T in the z-direction, out of the plane of the page, and extending from x = 0 to x = 1.00 m. Required:
Calculate the y component of the proton%u2019s momentum as they leave the magnetic field.

Gasoline comes from petroleum, which is made from ancient living things. petroleum, therefore, contains a type of energy. a. heat b. nuclear c. biological d. chemical potential

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?
