A(n) 0.49 kg softball is pitched at a speed of 13 m/s. the batter hits it back directly at the pitcher at a speed of 23 m/s. the bat acts on the ball for 0.014 s. what is the magnitude of the impulse imparted by the bat to the ball?

Awave travels at a speed of 5.2 m/s. if the distance between crests is 0.40 m, what is the frequency of the wave? use f=v/wavelength a. 13 hz b. 2.1 hz c. 0.077 hz d. 5.6 hz

Describe uniform velocity and variable velocity in short

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.
