Across a horizontal distance of 25 feet, a roller coaster has a steep drop. the height of the roller coaster at the bottom of the drop is -125 feet, compared to its height at the top of the drop. what is the average amount that the roller coaster's height changes over each horizontal foot?

X = total horizontal distance = 25 ft

Y = total vertical distance = 125 ft

x = horizontal distance = 1 ft

y = vertical distance = ?

using the equation

y = (Y/X) (x)

inserting the values

y = (125/25) (1)

y = 5 ft

hence for each horizontal foot, the average height change is 5 ft

or

25 ft horizontal distance traveled = 125 ft vertical distance dropped

dividing both side by 25

25 ft horizontal distance traveled/25 = 125 ft vertical distance dropped/25

1 foot horizontal distance traveled = 25 ft vertical distance dropped

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.

i think the answer would be b
