Explain or don't answer : 3 if the medium a wave is traveling through is constant, what about the wave can change? a: only its speed or frequencyb: both its frequency and wavelengthc: both its amplitude and speedd: both its speed and wavelength

B: both its frequency and wavelength

Explanation:

If the medium the wave is traveling through remains the same, the speed would stay the same.

  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
