An object with a mass of 1.5 kg accelerates 10.0 m/s^2? when an unknown force is applied to it. What is the amount of the force?

What is the momentum of a 2 kg object moving at 15 meters per second

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
