Two cars A &B are driving away from each other and sounding their horns. You are the driver of car A which is travelling at a speed of 27.2m/s and you measured the horn of the other car to be sounded at 730HZ, which is travelling at a speed of 24.08m/s. Speed of sound is 335m/s. Calculate the following: A a) Speed of the observer in m/s =

Light travels at a speed of about 3 103 m/s. (a) How many miles down a pulse of light travel in a time interval of 0.1 s, which is about the blink of an eye? (b) Compare this distance to the diameter of Earth.
(a) Use the distance and velocity data in Figure 3.64 to find the rate of expansion as a function of distance. (b) If you extrapolate back in time, how long ago would all of the galaxies have been at approximately the same position? The two parts of this problem give you some idea of how the Hubble constant for universal expansion and the time back to the Big Bang are determined, respectively. Figure 3.64 Five galaxies on a straight line, showing their distances and velocities relative to the Milky Way (MW) Galaxy. The distances are in millions of light years (Mly), where a light year is the distance light travels in one year. The velocities are nearly proportional to the distances. The sizes of the galaxies are greatly exaggerated; an average galaxy is about 0.1 MlY across.
You place your ear onto a steel railroad track and hear the sound of a distant train through the rails Δt = 3.2 seconds before you do through the air. The speed of sound in steel is vs = 6100 m/s, and the air temperature is 21° C. What is the distance, D, of the train in meters?
Consider an omnidirectional mobile robot with a ring of nine ultrasonic sensors (each with an opening angle of 40o) that are fired sequentially. Calculate the maximum length of time required for a complete 360o scan if the furthest object of interest is 6m away at any given time. Give your answer in seconds, to 3 decimal places. Assume the speed of sound in air is 343 m/s.
Can you explain it to me please
pls send me answer of this Question immidiately and i will give you like sir sure.
Can I please have this typed out on computer... I couldn't read the person who did it for me last and Now i'm reposting it up again because I didnt understand it. I will leave thumps up just for it being typed. THANK YOU.
then If you stood at the same point on a cold day were T2 = -7.5 °C how long is have taken for you to hear the echo in s?
Can you explain it ?
As you drive your car along a country road at night, a deer jumps out of the woods and stands in the middle of the road ahead of you. This occurs just as you are passing from a 55-mi/h zone to a 50-mi/h zone. At the 50-mi/h speed-limit sign, you slam on the car’s brakes, causing them to lock up, and skid to a stop inches from the startled deer. As you breathe a sigh of relief, you hear the sound of a police siren. The policeman proceeds to write you a ticket for driving 56 mi/h in 50-mi/h zone. Because of your preparation in physics, you are able to use the 25-m-long skid marks that your car left behind as evidence that you were not speeding. What evidence do you present? You must use work/energy methods to solve this problem!The coefficientsof friction between car tires and dry concrete are (s=1.0, k=0.80).
It’s takes 2.75s for sound to travel 908m how fast is the sound
If you stood at the same point on a cold day were T2 = -7.5 °C how long is have taken fou u to hear the echo in s?
