What property or properties of a wave determine it's speed?
mash [69]
The properties of the wave don't determine its speed. The properties of the medium do. You can FIND the speed by measuring the wave's frequency and wavelength.

A skier is pulled by a towrope up a frictionless ski slope that makes an angle of 12 with the horizontal. The rope moves paralle
MaRussiya [10]

Answer

given,

angle with horizontal = 12°

constant speed with the slope = 1 m/s

Work on the skier to move 8 m = 900 J

a) Rope moved with constant speed

change in kinetic energy is equal to zero

 work done by the force of the rope = 900 J

rate of force of the rope when skier move with

b) v = 1 m/s   total time t = 8 s

            Power =\dfrac{work\ done}{time}

                       =\dfrac{900}{8}

                       = 112.5 W

c) v = 2 m/s   total time t = 8/2 = 4 s

            Power =\dfrac{work\ done}{time}

                       =\dfrac{900}{4}

                       = 225 W
