A 440-Hz tuning fork is now used with a closed-end tube resonating column to determine the velocity of sound in a different gas than air. If the spacings between resonances are 1.10 m, what is the velocity of sound in this medium?

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)

How do you find the density of a cork

Physics pl 12)a body goes from p to q with a velocity of 10 m/s and comes back from q to p with a velocity of 20 m/s. what is the average velocity of the body during the entire trip? a)0 m/s b)13 m/s c)10 m/s d)15 m/s
