As you stand by the side of the road, a acr approaches you at a constant speed, sounding its horn, and you hear a frequency of 80.0 Hz. After the car goes by, you hear a frequency of 60.0 Hz. What is the speed of the car? The speed of sound in the air is 343 m/s. The answer shoudl be 49m/s, I am more confused on how to solve algebraically. I attached a photo of how far I made it lol.

A section of superconducting wire carries a current of 100 A and requires 1.00 L of liquid nitrogen per hour to keep it below its critical temperature. For it to be economically advantageous to use a superconducting wire, the cost at cooling the wire must be less than the cost of energy lost to heat in the wire. Assume that the cost of liquid nitrogen is $0.30 per liter, and that electric energy costs What is the resistance of a normal wire that costs as much in wasted electric energy as the cost of liquid nitrogen for the superconductor?

Using the given charge-to-mass ratios for electrons and protons, and knowing the magnitudes of their charges are equal, what is the ratio of the proton's mass to the electron's? (The charge-to-mass ratios for electrons and protons are −1.7588×1011 C/kg and 9.5788e7 C/kg , respectively. Note that since the charge-to-mass ratios are given to five-digit accuracy, your answer may differ from the accepted ratio. Round your answer to at least five significant figures.) Mp/Me =
