The weight of an object is the product of its mass, m, and the acceleration of gravity, g (where g=9.8 m/s2). if an object’s mass is m=10. kg, what is its weight?

Simple machines can a. increase force only b. decrease force only c. increase or decrease force

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.)
