7. In outer space, two astronauts sit at rest next to each other. Bruno, the larger astronaut whose mass is 100 kg, is twice as massive as Timmy, the smaller astronaut. If Bruno pushes
Timmy with a force of 100N, how far apart will they be in 2 seconds?

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

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

How is the gravitational force related to the distance between two objects?
