15. सिम्ररनको तौल पृथ्विको सहतमा 600N छ भने उनको तौल 300N हुनको लागि I (R= 64 x 105m) (If Simran's weight is 600N on the earth. How far should she be from the centre of
the earth so that his weight will be 300N? (Radins of earth is
64 x 105m)​

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

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

The transfer of heat through the movement of a gas or liquid a. convection b. conduction c. radiation
