Answer:
E = 0.024 ×10⁻¹⁷ J
Explanation:
Given data:
Wavelength of photon = 821 nm (821 ×10⁻⁹ m)
Energy of photon = ?
Solution:
Formula:
E = hc/λ
h = plancks constant = 6.626×10⁻³⁴ Js
c = speed of light = 3×10⁸ m/s
by putting values
E = 6.626×10⁻³⁴ Js × 3×10⁸ m/s / 821 ×10⁻⁹ m
E = 19.878×10⁻²⁶ J.m/ 821 ×10⁻⁹ m
E = 0.024 ×10⁻¹⁷ J
A. The amount of randomnes in the system
Nitrogen, also known as "N", with a mass of 14.0067 u and the atomic number of 7, is known mostly an element (it is a chemical element) and when it is elements like this, it is in a periodic table (Fun Fact: Nitrogen is colorless and an unreactive odorless gas element.) It is an element.
Hope this helped!

Dear friend,
How are you doing? I finally switched to my new school and it's been so hard adjusting. But I know I have a new chance at making new friends and memories. Also, I can learn new things, like interacting with new people and how to keep my anxiety low. I really miss us hanging out and how much we'd laugh and get in trouble at class. But i really hope to see you soon & that it hasn't gone terribly wrong for you since i left.
your friend,

Kepler’s third law exhibits the relationships between the distance of a planet from the sun and the period of its revolution. Kepler’s third law is also sometimes referred to as the law of harmonies.
Kepler’s third law compares the orbital period and the radius of an orbit of a planet to the distance of the planet to the sun. It states mathematically that the more distant a planet is from the sun the greater its orbital period will be. The period of revolution of a planet is measured in days, weeks, months or years. For example, Earth’s period of revolution is 365 days.
