Acar travels at a velocity of 10 m/s north for 50 s. which of the following
equations correctly determines the car's displacement?
a) displacement = 50 s/(10 m/s)
b) displacement = (10 m/s north) /50 s
c) displacement = (10 m/s north) * 50 s
d) displacement = 50 s/(10 m/s north)

Explanation:

Given that,

Velocity of car, v = 10 m/s (towards north)

Time, t = 50 s

The shortest path covered by the car is called its displacement. Mathematically it is given by

d = v × t

v is the velocity of the car

t is the time taken

Here, displacement = (10 m/s north) × 50 seconds

So, the correct option is (c).

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.
