scientists observe an approaching asteroid that is on collision course with earth. they devise a plan to launch a rocket that will collide withe the asteroid inelastically and stop it. the mass of the asteroid is 11,000kg and it’s approaching earth at 50m/s. if the rocket has a mass of 1700kg, approximately what velocity must it have to completely stopping the asteroid after collision?

a. -516m/s
b. -324m/s
c. 105m/s
d. 212m/s

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
