The law of conservation of angular momentum states that if no external force acts on an object, then its angular momentum does not change. true or false

There are weak or strong attractive forces between atoms of liquids with a high viscosity

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

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.)
