Answer:
Explanation:
The energy
of a photon is given by:
(1)
Where:
is the Planck constant
is the frequency light
On the other hand, there is an inverse relationship between
and the wavelength
:
(2)
Where:
is the speed of light
is the wavelength
Substituting (2) in (1):
(3)
Finally:
This is the energy of a photon of blue light, in Joules.
Well, the diameter of a circle is simply a length, so your measurement will have units of length. We just have to find an answer that has only units of length.
A). gram, second . . . mass and time. That can't be it.
B). kilogram, ampere . . . mass and current. That can't be it.
C). centimeter, meter . . . both lengths. This one is looking good.
D). candela, mole . . . light intensity and some chemical thing. That can't be it.
So it can't be anything else on this list but <em>C</em> .
Whenever an object is falling, its potential energy
is decreasing and its kinetic energy is increasing.
Olivia's potential energy is decreasing and her kinetic energy
is increasing as she moves toward the right side of the picture,
all the way from W, through X, to the bottom of the arc.
