The correct option is A.
Elements are substances that are made up of atoms of the same type., while compounds are made of two or more atoms of different types.
Some common examples of elements are Iron, Sodium, oxygen, Hydrogen, while NaCl ( Sodium Chloride), Water (H_2O) , Ammonia (NH_3) are compounds.
It can be seen that the compounds are composed of atoms of different substances.
Chlorine is a diatomic molecule, where two Chlorine atoms are bonded by a covalent bond. Since both atoms in a Chlorine molecule are the same, it cannot be called a compound.
Hence Chlorine, though it has more than one atom in its molecular form, is still called element.
<span>If u want only WHether the total resistance is
less than 2 or less than 5 or more than 5 ohms: there is a Simple way.
When you connect resistances in parallel, resultant resistance is always
smaller than all of them. So it is less than 2 ohms</span>.
Answer:
The constant of proportionality between charge and voltage is the capacitance.
Explanation:
The capacitance (
), measured in farads, is the ratio of charge to voltage, that is:
Where:
- Charge, measured in coulombs.
- Voltage, measured in volts.
If charge is clear, it is easy to concluded that capacitante is a constant of direct proportionality.
Hence, the correct answer is B.

In fact, the dog walks north for 10 meters and east for another 10 meters. The path of the dog can be represented with two vectors, A pointing north (of magnitude 10 meters) and B pointing east (of magnitude 10 meters). The direction of the resultant vector (due to east) will be given by
and the direction will be north-east.
