c. hydrogen.
Explanation:
Earth is full of different substances. Hydrogen bonding is a partial inter molecular bonding between a lone pair and an electron rich donor. Some of the most important molecules here on earth are held by hydrogen bonding.
Hydrogen bonding is useful in inorganic and organic molecular combination.
Answer:
Ratio = 9 : 2
Explanation:
We have been given two resistors, one with 2ohms rating and another with 4 ohms rating.
First they are connected in series. When resistors are connected into series, Equivalent resistance is given by:
Resistance (Equivalent) = R₁ + R₂ = 6 ohms
When these are connected in parallel, equivalent resistance becomes:
1 / Resistance (Equivalent) = 1/R₁ + 1/R₂ = 1/2 + 1/4
1 / Resistance (Equivalent) = 3/4
Resistance (Equivalent) = 4/3
Ratio = R(Series)/ R(Parallel)
Ratio = 6 : 4/3
Ratio = 18 : 4
Ratio = 9:2
