This 80 kg roller coaster car weighs how many newtons? How much does gravity pull it down?? This 80 kg car is moving at 20 m/sec at the top where the hill's radius is 100m. What is the centrifugal force?

Will it fly off at the top?

This 80 kg car is moving at 40 m/sec at the bottom where the radius is 50m. What's the centrifugal force there?

What's the total force down at the bottom then?

Someone please awnsers all these question!

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.
