Answer:
1.59 x 10⁻²⁵ J.
Explanation:
- The energy of a photon is calculated Planck - Einstein's equation:
E = h ν
, where
E is the energy of the photon,
h is Planck's constant <em>(h = 6.626 x 10
⁻³⁴ J.s)</em>
ν is the frequency of the photon
-
There is a relation between the frequency (ν
) and wave length (λ).
λ.ν = c,
where c is the speed of light in vacuum (c = 3
.0 x 10
⁸ m/s).
λ = 125 cm = 1.25 m.
<em>Now, E = h.c/λ.</em>
∴ E = h.c/λ = (6.626 x 10
⁻³⁴ J.s) (3
.0 x 10
⁸ m/s) / (1.25 m) = 1.59 x 10⁻²⁵ J.
Answer: Bb
Explanation:
The capital B (purbred black fur) is domaint the the lower case b(purebred white fur)
non-Metals:
Nitrogen.
Oxygen.
Helium.
Sulfur.
Chlorine.
Explanation/Answer:
Metal atoms have only a few electrons in their outer shell whereas non-metal atoms have lots of electrons in their outer shell. This means that metals tend to react with non-metals. When a metal reacts with a non-metal, electrons transfer from the metal to the non-metal.
HOPE I HELPED!!
So that every measurement is accurate.. hope this helps
I would say Frost Wedging because water must move, a physical act, and then in must freeze, also a physical act, and then the act of it freezing causes cracks known as frost wedging and that is definitely a physical act. Hope that helps!
