Ablock of mass m slids up a ramp making an angle θ with the horizontal. the block has an initial ke of 1 2 m v2 0 as it starts up the ramp and travels a distance l along the ramp before coming to momentary rest. v0 l how much work did kinetic friction do on the block between its starting point and the point it came to momentary rest?

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

Which of the following is an example of motion in two dimensions?

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
