A2000kg car is moving at 200m/s on horizontal road accelerates uniformly and come to rest in 3 seconds what is the magnitude of frictional force that is responsible for this effect

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
