For this problem we can use 2 equations.
(1) - E = mC²
E = Energy of photon (J)
m = Mass of photon (kg) (1.67x10⁻²⁷ kg)
C = speed of light (3 x 10⁸ m/s)
(2) - E = hf
E = Energy of photon (J)
h = plank's constant (6.63 × 10⁻³⁴<span>J s)
f = frequency of the photon (Hz)
(1) = (2)
hence, </span>mC² = fh
by rearranging,
f = mC² / h
f = 1.67x10⁻²⁷ kg * (3 x 10⁸ m/s)² / (6.63 × 10⁻³⁴J s)
f = 2.27 x 10²³ Hz
Answer:
Emulsion
Explanation:
Emulsion is a special type of mixture formed by combining two liquids that do not normally mix. An example of emulsion is;
Oil and Water
Answer:
Yes
Explanation:
A single covalent bond forms when two atoms share one pair of electrons.
Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference. Such bonds exists between molecules of non-metals.
- To form a covalent bond, each of the two participating atoms would put down an unpaired electron.
- The unpaired electrons form a shared pair of electrons between them.
- This shared pair of electrons constitutes the electron cloud that binds the two atoms together.
- The shared pair of electron is the covalent bond.
going down the the periodic table, the number of shells increases resulting in an obvious increase in the atomic radii of the elements
Answer:
Because its source is the almost unlimited amount of heat generated by the Earth's core. Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be reinjected, making it a sustainable energy source.
