please explain part d An ambulance moving in still air at a constant speed of v, =135.0 km / h, on a straight5.road, has a horn that emits sound at a frequency f =1450 Hz. Assume that the speed of soundin the still air is v=350 m/s.a) What is the frequency fi of the sound heard by an observer standing still on the road as theambulance approaches?b.) What is the wavelength, 4, of the sound in the still air directly in front of the ambulance asit is approaching?c.) What is the frequency f, of the sound heard by a moving observer moving directly towardthe approaching ambulance at a speed v, = 95.0km / h?d.) Suppose that the sound from the ambulance is reflected off of a reflector moving directlytoward the approaching ambulance at a speed v, -95.0km / h. Assuming that the sound canbe heard, what is the frequency f, of the reflected sound wave heard by the ambulancedriver?

(a) What is the speed of sound in the tube? (b) How far from the open end will the piston cause the next mode of resonance?
During a 4th of July celebration, an M80 firework explodes on the ground, producing a bright flash and a loud bang. The air temperature of the night air is TF=90.00F . Two observers see the flash and hear the bang. The first observer notes the time between the flash and the bang as 1.00 second. The second observer notes the difference as 3.00 seconds. The line of sight between the two observers meet at a right angle as shown below. What is the distance x between the two observers?
