Answer:
1. frequency = 7.39 * 10¹⁴ Hz
2. wavelength = 1.44 * 10⁸ nm
Explanation:
The speed, frequency and wavelength of waves are related by the formula;
speed = wavelength * frequency
1. wavelength of light = 406 nm = 4.06 * 10⁻⁷ m
speed of light is a constant = 3.0 * 10⁸ m/s
From the formula above, frequency = speed / wavelength
therefore, frequency = (3.0 * 10⁸ m/s) / 4.06 * 10⁻⁷ m
frequency = 7.39 * 10¹⁴ Hz
2. From the equation above, wavelength = speed/frequency
speed of radiation = 3.0 * 10⁸ m/s
frequency = 2.09 * 10⁹ Hz or 2.09 * 10⁹ s⁻¹
therefore, wavelength = (3.0 * 10⁸ m/s) / 2.09 * 10⁹ s⁻¹
wavelength = 1.44 * 10⁸ nm
Answer:
edge length = 3.61 cm
Explanation:
Givens
m = 369 gm
d = 7.86 gm / cm^3
v = ?
Formula
v = m / d
Solution
v = 369 / 7.86
v = 46.95 cm^3
============
That's not the answer. You must take the cube root of the volume
side = cube root (46.95)
side = 3.61 cm
The term Rutherford gave to the positively charged particles in the nucleus of an atom was/is Proton.

Answer:
Tend to keep the product concetration <u>low</u> and therefore drive the reaction <u>righward</u>
Explanation:
The fact the products of a reaction are quickly consumed by the next one would tend to keep the product concetration low and therefore drive the reaction righward (to the products).
This happens because the system will not achive equilibrium between the reactants and the product, and will keep producing it util the system achives equilibrium or the reactants dry out.
