If a car moves with a uniform speed of 2m/s in a circle of radius 0.4m, what is its angular speed?

The car's angular speed is .

Explanation:

Angular velocity is usually measured with , so I'm going to use that to answer your question.

The relationship between tangential velocity and angular velocity (ω)  is given by:

Using the values from the question, we get:

Therefore, the car's angular speed is .

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.

correct it is c.) b b
