Who is the founder of oersted experiment ?

True or false: the cycle of seasons on the earth is caused by the tilt of the earth on its axis toward and away from the sun.

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.

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter
