You are the receiver in a trapeze duo and are practicing your timing. The swings are spaced so that if your partner, the jumper, releases when his swing is at 45° and flies through the air at a speed of 3m/s , he will be caught at the top of his trajectory when your swing is at 45°. Assume your swings are of equal length, that your swings start at the same angle, and the speed of both swings are equivalent. Required:How much later than your partner must you leave your platform and start your swing to complete the stunt?

How many molecules are present in 3 mols of silicon dioxide (sio2)?

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.
