At an air show a jet flies directly toward the stands at a speed of 1200 km/h, emitting a frequency of 3500Hz, on a day when the speed of sound is 342 m/s. What frequency is heard

  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
