9. If the frequency of a certain light is 3.8 x 10
Hz, what is the energy of this light?

E = h*f = (6.63*10^-34) *( 3.8*10)

E = 2.5 *10^-32

Explanation:

e= Energy

h = Planck's constant

f = frequency

  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

force tends to be low and long diustance masses are high
