What is the period, t, of a wave produced by a tuning that makes 400 vibrations in one second? group of answer choices
2.0 s
0.0025 s
0.005 s
10 s
5.0 s

T=0.0025s

Explanation:

Vibrations per second is the definition of the S.I. unit Hertz (Hz), which is a frequency. This means that 400 vibrations in one second refers to a frequency of 400Hz. We can get our period T in seconds by using the formula T=1/f, which for our case is:

T=1/f=1/400Hz=0.0025s

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.

another example of kinetic energy would be,

kinetic energy   >     moving energy
