Pakistan MCQs

Since 12 × 13 = 156, subtracting gives 157 - 156 = 1.
Thus, the remainder is 1.

Division and multiplication have equal priority and are performed left to right.
So 48 ÷ 6 = 8, and 8 × 3 = 24.

Multiplication is performed before addition.
Thus, 3 × 4 = 12 and 5 + 12 = 17.

It is composed of atoms, molecules, or ions.

A vector has both magnitude and direction.
Acceleration describes the rate and direction of velocity change.

An element cannot be broken down chemically into simpler substances.
Each element is identified by its atomic number.

Both sides of a valid physical equation must have the same dimensions.
Dimensional analysis can reveal inconsistent formulas.

Compounds have definite formulas and characteristic properties.
Their components can be separated only by chemical means.

The newton is derived from base units as kg·m/s².
Metre, kilogram, and second are base units.

Mixture components retain much of their individual identity.
They can often be separated by physical methods.

Solutions are homogeneous mixtures.
Any sampled portion has approximately the same composition.

Heterogeneous mixtures contain distinguishable regions or phases.
Examples include sand in water and granite.
