1. Radio waves from an FM station have a frequency of 103.1 MHz. If the waves travel with a speed of 3.00 x 108 m/s, what is the wavelength?
2. A spring (k = 790 N/m) has a length of 48 cm when zero net force is applied to it. What will its length be when 230 N of force is applied to stretch it?
3. If 320 J of work is done on a spring with a spring constant of 720 N/m, how far will it stretch?
4. A pendulum clock is taken to another planet's moon (g = 3.6 N/kg). How long must the pendulum be in order for the clock to continue keeping accurate time (1 second/cycle)?
5. How much work must be done on a spring (k = 730 N/m) to stretch is by 2.5 m?
6. A string vibrates with a standing wave that has a wavelength of 1.2 m. What is the length of the string?
