Explanation

In a Geometric Progression, the nth term is given by:

Tn​=a×r^n−1

Where:

• a = first term

• r = common ratio

• n = term number

Explanation

The slower motion of a pendulum is due to a longer period, which is related to the weaker gravitational force at higher altitudes

K2, being a very high mountain, has a significantly lower value of acceleration

Due to gravity, cities like Karachi, Murree, or Lahore result in a slower pendulum motion. 

Explanation

6P4 = 6 × 5 × 4 × 3 = 360.

Explanation

 Electromagnetic force is a scalar quantity.

Force is defined as the product of mass and acceleration and force is a vector quantity.

This is the pair in which one physical quantity is scalar and the other is a vector.

Explanation

Aₙ = a + n × d, where d = common difference  

Here, A₁ = a + d, A₂ = a + 2d, ..., b = a + (n+1)d

So,  

Aₙ = a + n × [(b − a)/(n + 1)]

Explanation

Active Voice: The cat chased the rat.

(Subject = cat, verb = chased, object = rat)

Passive Voice: The rat was chased by the cat.

(Object becomes subject, verb changes to passive form)

Explanation

A local area network  is a group of computers and associated devices that share a common communications line or wireless link to a server.

Modem is a combined device for modulation and demodulation.

For example, between the digital data of a computer and the analogue signal of a phone line.
