The planet Mars has a mass of 6.417×1023 kg. The small moon Phobos orbits Mars in a near circular orbit at an orbital distance (from the centre of Mars to the centre of Phobos) of 9,376 km. Phobos has a mass of 1.066×1016 kg and a mean radius of 11.27 km. As an approximation you may assume the moon is spherical. It is in a tidally locked orbit so that the same side of Phobos faces Mars all the time.

Calculate the angular velocity w of Phobos

We found the centripetal acceleration of the earth as it revolves around the sun. compute the centripetal acceleration of a point on the surface of the earth at the equator caused by the rotation of the earth about its axis. (enter the magnitude. the radius of the earth is 6,371 km.)

When someone slams her books on a table the kinect energy is transferred into vibrations that travel to your ears as sound waves which statement describes the movement of those waves

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.)
