Knowing that 0.80kg object weighs 8.0n find the acceleration of a 0.80kg stone in free fall

J. j. thomson’s experiment disproved the theory that an atom

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

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.)
