SOLVE THIS EQUATION FAST...​

Answer» N:-If √3 tan θ = 3 sin θ then prove that sin² θ - cos² θ = 1/3.Answer:-Given:-√3 tan θ = 3 sin θUsing tan θ = sin θ/cos θ in LHS we GET,Now,We have to prove:-sin² θ - cos² θ = 1/3Using sin² θ = 1 - cos² θ we get,⟹ 1 - cos² θ - cos² θ = 1/3Putting the value of cos θ we get,⟹ 1 - (1/√3)² - (1/√3)² = 1/3⟹ 1 - 1/3 - 1/3 = 1/3⟹ (3 - 1 - 1)/3 = 1/3⟹ 1/3 = 1/3Hence, Proved.

Define molecular mass taking c-12 isotope as the standard substance please answer ASAP​

Answer»

∴ Gram atomic mass of oxygen = 16 g.Molecular MassThe molecular mass of a SUBSTANCE is the number of times the molecule of the substance is heavier than one-twelth the mass of an atom of carbon -12. Or, the molecular mass is equal to the sum of its atomic masses of all the atoms present in one molecule of a substance. For EG: Water (H2O)Atomic mass of H= 1 unitAtomic mass of O =16 unitsThe molecular mass of water = 2 × atomic mass of H+1 × atomic mass of O= 2 × 1 + 16 × 1= 18 unitsGram Molecular MassThe molecular mass of a substance EXPRESSED in grams is the gram molecular mass. For eg: Molecular mass of oxygen = 32u∴ Gram molecular mass of oxygen = 32 gExplanation:Carbon-12 is of PARTICULAR importance in its use as the standard from which atomic masses of all nuclides are measured, thus, its atomic mass is exactly 12 daltons by definition. Carbon-12 is composed of 6 protons, 6 neutrons, and 6 electrons.
