The oscillation of rod oa about o is defined by the relation θ 5 (3yπ)(sin πt), where θ and t are expressed in radians and seconds, respectively. collar b slides along the rod so that its distance from o is r 5 6(1 2 e22t ) where r and t are expressed in inches and seconds, respectively. when t 5 1 s, determine (a) the velocity of the collar, (b) the acceleration of the collar, (c) the acceleration of the collar relative to the ro

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.

where's the following? you gotta add it to know what the choices are

explanation:

come closer and become far apart and become steam/gas

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
