Explanation

Paksat-IR was launched on August 11, 2011, as Pakistan’s first geostationary communication satellite.

It was developed with the help of China.

It provides telecommunication and broadcasting services.

Explanation

Community represents the practical aspect of society’s ideology, as it reflects shared values, norms, and interactions among individuals.

It plays a crucial role in shaping social behavior, traditions, and collective identity within a society.

Explanation

Ohm’s Law states that V = IR, where voltage (V) is directly proportional to current (I) and resistance (R).

It is the fundamental principle describing the relationship between voltage, current, and resistance in electrical circuits.

Explanation

Scientific knowledge is based on observable, empirical evidence and is restricted to the material world.

It relies on experiments, observations, and logical reasoning rather than intuition or revelation.

Explanation

The multiplicative inverse of a number is the number that, when multiplied by the original number, gives a product of 1.

The multiplicative inverse of 0 does not exist, because:

0 × x = 0 ≠ 1

for any real number x.

The correct answer is: 0

Explanation

Basic assumptions (also called axioms or postulates) are statements accepted as true without proof.

Theorems, on the other hand, require proof based on these assumptions.

Explanation

A regular polygon has all sides and angles equal.

Among triangles, only an equilateral triangle has all three sides and angles equal, making it a regular polygon.

Explanation

To simplify the expression, follow the rules of exponents:

(x⁴)³ = x^(4×3) = x¹²

Now, divide x¹² by x⁻⁴:

x¹² ÷ x⁻⁴ = x¹² × x⁴ (since dividing by x⁻⁴ is the same as multiplying by x⁴)

= x^(12+4)

= x¹⁶

Explanation

Scuba tanks contain a mixture of nitrogen (N₂) and oxygen (O₂), commonly called compressed air or nitrox.

Nitrogen prevents oxygen toxicity at high pressures, which can occur in deep-sea diving.

Explanation

When comparing two things, we usually use better, but since "this is the" is present, we need the superlative form (best).

Good is the positive form.
