Q1. A student in a parked car honks the horn that has a `proper' frequency of 310.00 Hz. An observer in an approaching vehicle measures the frequency of the sound to be 336 Hz. analyse the speed of the approaching vehicle. Utilize 340 m/s as the speed of sound in air.
Q2. Suppose that you have two objects, one with a mass of 8 kg and the other with a mass of 18 kg, each with a charge of -0.029 C and separated by a distance of 8 m.
What is an electric force that these objects exert on one another?
Q3. One displacement vector A has magnitude of 2.78 km and point due north. Another displacement vector B has a magnitude of 7.40 km and also points due north. Provide diagrams and calculate the magnitude and direction of A+B, B-A, A-B.
