If the andromeda galaxy collided with the milky way, what would most likely happen to earth?

Which feature indicates that mars resides in the inner region of the solar system

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

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.
