Q1. A steel wire with mass 20.8 g and length 1.09 m is strung on a bass so that the distance from the nut to the bridge is 1.00 m. figure out the linear density of the string, What velocity wave on the string will produce the desired fundamental frequency of E1 string, 43.09 Hz, compute the tension required to obtain the proper frequency.
Q2. Speedboat A negotiates a curve whose radius is 198 m. Speedboat B negotiates a curve whose radius is 290 m. Each boat experiences the same centripetal acceleration. What is the ratio vA/vB of the speeds of boats?

A diffraction grating with 330 {rm lines/mm} is 1.00 {rm m} in front of a screen. What is the wavelength of light whose first-order maxima will be 17.0 {rm cm} from the central maximum on the screen.
The radar system at an airport broadcasts 15 GHz with 150 kW. An approaching airplane with a 34 m^2 cross section is 24km away. Assume that the radar broadcasts uniformly in all directions and that the airplane scatters microwaves uniformly in all di..
An old trick to find out if a train is coming is to put your ear on the rails of the track. Why is this more effective than just listening for the sounds the train makes in air.
