Astar of mass 3 × 1030 kg is located at < 6 × 1012, 2 × 1012, 0> m. a planet of mass 6 × 1024 kg is located at < 4 × 1012, 4 × 1012, 0> m and is moving with a velocity of < 0.6 × 104, 1.1 × 104, 0> m/s. (a) during a time interval of 1 × 106 seconds, what is the change in the planet's velocity?

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm
