If you push on a cart on a railroad with a force of 500 N and it doesn't move, you can conclude that a. the cart has too much mass to accelerate
b. the force is canceled by the reaction force.
c. there is a force of 500 N in the opposite direction acting on the cart.
d. the normal force is greater than 500 N.
e. Newton's second law is not valid in such a frame of reference.

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.

momentum of soft ball three times less than baskey ball

pretty sure it's false

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
