Answer:
λ = 5.434 x 10⁻⁷ m = 543.4 nm
Explanation:
To solve this problem we can use the formula provided by Young's Double Slit experiment:
where,
λ = wavelength of light = ?
Δx = distance between adjacent bright fringes = 1.6 cm = 0.016 m
d = slit separation = 0.18 mm = 0.00018 m
L = Distance between slits and screen = 5.3 m
Therefore,
<u>λ = 5.434 x 10⁻⁷ m = 543.4 nm</u>
Answer:
a) acceleration
Explanation:
Acceleration is, by definition, the change of an object's velocity.
Answer:
I think it is D but don't count on it
Answer:
13.0186g/mole
63.0326g/mole
Explanation:
Given parameters;
Compounds - CH
CH₃O₃
To solve this problem, let us delve a bit into molar mass of a substance;
The molar mass of a substance (atom or molecule or compound) is the mass in grams of one mole of the substance.
Simply add the component atomic masses to find this number;
Atomic mass of Carbon = 12.0107g/mole
Hydrogen = 1.0079g/mole
Oxygen = 15.9994g/mole
Molar mass of CH = 12.0107 + 1.0079 = 13.0186g/mole
Molar mass of CH₃O₃ = 12.0107 + 3(1.0079) + 3( 15.9994) = 63.0326g/mole
