The center of the moon is 0.0026 au (3.890 x 10^8 m) from the center of the earth and has a relative mass of 0.0123. locate the cm of the earth-moon system with respect to the center of the earth. with respect to the center of the moon. find the ratio of orbital velocities of the earth and moon about the cm of the system. if the orbital velocity of the moon is 1012 m/s, what is the approximate orbital velocity of the earth about th

What are igneous intrusions and extrusions

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.)

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
