A tube closed at one end is used to determine the speed of sound in air. The resonances occur every 32 cm when a 530-Hz tuning fork is vibrated. What is the velocity of the sound?

Modify the equation fδt=δ (mv) to find the force of friction.

Could someone me find the answer to this problem.

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
