6.1 Mastery Check You and your brother are pushing a 2400 kg car with a dead battery. You push with a force of 20 N and your brother pushes with a force of 25 N in the same direction. There are no other forces acting on the car. What is the acceleration of the car?

none, its a machine

b.a device that inputs heat into a cool object

your answer is, orbit around the nucleus

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
