Mass of ball = 0.052 kg Layla and Kai place a steel ball on the laboratory bench.
They can apply two forces of magnitude 3.0N and 4.5 N to the ball.
The direction of the forces can be changed.
(a) How should they direct the two forces to produce the maximum acceleration of the ball?
Calculate this maximum acceleration.
Direction of force

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.

Agraduated cylinder contains 63.0 ml of water. a piece of gold, which has a density of 19.3 g/ cm3, is added to the water and the volume goes up to 64.5 ml. calculate the mass in grams of the gold that was added to the water. explain how you got your answer.

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
