a 900 w microwave generator in an oven generates energy quantra of frquenecy 2560 mhz how many energy

1.6E-32J

Explanation:

Using

Energy= power x time

And E= hf

hf= Pt

t = hf/p= 6.6*10^-34x 2560*10^-3/900

= 18.7*10^-37s

So E = pt

= 900 x 1.8E-37

1.6x10^-32J

a coal burning power plant

  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
