Which statement best describes the superposition principle?

A.) If two in-phase waves arrive simultaneously at a point, their amplitudes add up.

B.) If two out-of-phase waves arrive simultaneously at a point, there amplitudes add up.

C.) If two in-phase waves arrive at a point one after another, their amplitudes add up.

D.) If two out-of-face waves arrive at a point one after the other, their amplitudes add up.

Explanation:

A.) If two in-phase waves arrive simultaneously at a point, their amplitudes add up.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
