If the same net force is applied to a 7 kg object and a 21 kg object, then

the 21 kg object accelerates three times faster than the 7 kg object.

the 7 kg object accelerates three times faster than the 21 kg object.

both objects accelerate at the same rate because the force is the same.

neither object will accelerate because there is a net force on the objects

what is the acceleration due to gravity on mars?

9.8 m/s2

c.

12.2 m/s 2

b.

3.7 m/s2

d.

0.3 m/s2

the force that pulls falling objects toward earth is call

Avery hard rubber ball (m = 0.5 kg) is falling vertically at 4 m/s just before it bounces on the floor. the ball rebounds back at essentially the same speed. if the collision with the floor lasts 0.05 s, what is the average force exerted by the floor on the ball?

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called

What is the name for the remnant of an asymptotic giant that has lost its shells? black dwarf white dwarf yellow giant black hole
