Answer:
9.133×10^-6 m
Explanation:
A photon is the smallest discrete amount or quantum of electromagnetic radiation. It is the basic unit of all light. Photons are always in motion and, in a vacuum, travel at a constant speed to all observers of 3 x 10^8 m/s.
From the question, the following details were supplied;
Energy of the photon (E) = 4.61×10^−19 J
Speed of light (c) = 2.99×10^8 m/s
Plank's constant (h) = 6.626×10^−34 J⋅s
Wavelength of the photon (λ)= ??? The unknown
From
E=hc/λ
λ= hc/E
Substituting values
λ= 6.626×10^−34 × 2.99×10^8/ 4.61×10^−19
λ= 91.33×10^-7 m
λ= 9.133×10^-6 m

Answer:
See the answer below
Explanation:
From the illustration;
1 chain = 20.1 meters
1 talent = 30.2 kg
<em>The map says the treasure chest was buried 27 chains due west and 3 chains deep under the ground.</em>
27 x 20.1 = 542.7 meters.
3 x 20.1 = 60.3 meters
<u>This means that one would need to travel 542.7 meters due west from the US Capitol and dig 60.3 meters under the ground in order to locate the treasure chest.</u>
<em>The treasure chest has 50 talents of gold:</em>
50 x 30.2 = 1,510 kg of gold.
Answer:The product of the given expression is :
Explanation:
Given expression:(n + 8)(n - 2)
Using identity:
a = n, b=8, c= (-2)
The product of the given expression is :
Knowing the two variables in this problem are volume (liter) and pressure (atm), we can determine that the law ought to be used would be Boyle's Law.
Boyle's Law: P₁v₁=P₂V₂
Using the question, we can find:
P₁ (initial pressure)=0.24 atm
V₁ (initial volume)=77.0L
P₂ (standard pressure)= 1.00atm
V₂=?
We can rearrange the equation to solve for V₂: V₂=P₁V₁/P₂
Next, we can plug in the values: V₂=
We would receive an answer of 18.48 L. However, it appears that the significant digits would be 3 as both 77.0 and 0.24 have 3 digits. As such, the answer would be 18.5L of gas at 1.00atm.
