FM radio stations use different frequencies. For example, the radio station 93.3 has a
frequency of 93.3 Megahertz (MHz). Your
friend has the following four radio stations
preset on the stereo in her car. Which of these
stations would you expect to have the longest
wavelength? Explain your answer.
89.5 FM
92.5 FM
95.7 FM
101.5 FM

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
