What is the wavelength of a wave that is traveling at 343 m/s with a frequency of 1000 Hz

The experiments with static charges were done by:

Aclarinetist, setting out for a performance, grabs his 3.350 kg clarinet case (including the clarinet) from the top of the piano and carries it through the air with an upward force of 24.65 n. find the case's vertical acceleration. indicate an upward acceleration as positive and a downward one as negative.

Acar travels in reverse. it covers 150 meters in 12 seconds what is the velocity of the car what is the speed of the car
