A meter stick is pivoted at the left end and released from rest at an angle 30o above horizontal. The mass of the meter stick is 0.065 kg. As it swings down in a circle: What is the instantaneous angular acceleration of the meter stick?
What is the maximum angular acceleration of the meter stick?
What is the maximum angular velocity of the stick?
What is the maximum linear speed of any piece of the meter stick during the motion?

The process in which the nucleus of an atom splits into two lighter atoms, releasing a large amount of energy is nuclear

When an object is heated it contracts. a. true b. false

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.
