A sphere of mass 1.15 kg is suspended from a string in a room in Osmond Lab. The sphere is accelerated upwards by pulling on the string to which the sphere is attached. Its speed increases from 2.11 m/s to 4.74 m/s in a time of 1.68 s. The tension is constant during this time. Calculate the tension in the string.

Two polarizers are oriented at 24.0∘ to one another. light polarized at a 12.0-degree angle to each polarizer passes through both. what is the transmitted intensity (%)?

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?

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.)
