The answer is; Relative dating
This type of dating is not concerned with determining the absolute age of rock. It compares between rock layer and determines which is younger or older in comparison. Therefore relative dating is significant in arranging geologic events based on the stratigraphy of rock layers.
Answer:
Explanation:
Mass ( m ) = 52 kg
Acceleration ( a ) = 5 m / s²
Force ( F ) = ?
According to Newton's second law of motion ,
Hope I helped!

Density is defined as the mass per unit volume,
mass of the solution is therefore
mass = density x volume
1 gal = 3785.41 mL
therefore 14.1 gal = 3785.41 x 14.1 = 53 374.3 mL
mass of gasoline required = 0.737 g/mL x 53 374.3 mL
mass of gasoline required to fill the tank - 39 337 g = 39.3 kg
39.3 kg of gasoline is required

Answer:
203 grams
Explanation:
<em>It is known that 1.0 mole of a compound contains Avogadro's number of molecules (6.022 x 10²³).
</em>
<em><u>Using cross multiplication:</u></em>
1.0 mol contains → 6.022 x 10²³ molecules.
??? mol contains → 7.2 x 10²⁴ molecules.
∴ The no. of moles of (6.3 x 10²⁴ molecules) of NH₃ = (1.0 mol)(7.2 x 10²⁴ molecules)/(6.022 x 10²³ molecules) = 11.96 mol.
<em>∴ The no. of grams of NH₃ present = no. of moles x molar mass </em>= (11.96 mol)(17.0 g/mol) = <em>203.3 g ≅ 203.0 g.</em>
