Ally conducts a physics experiment to determine the speed of sound in air. Using the resonance set up as shown in fig. She uses a tuning fork of frequency 388 Hz and determines the first resonating length of the air column to be 0.22 m. Determine the temperature of air in the room. (speed of sound in air at 0° C = 331m/s; it increases by 0.6 m/s for every1° C rise in temperature).

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
