Explanation

The transpose of a row matrix is a column matrix.

Similarly, the transpose of a column matrix is a row matrix.

In essence, when transposing a matrix, you swap rows with columns.

So, a matrix with one row becomes a matrix with one column, and vice versa. 

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

Chloroform, or trichloromethane, is an organic compound with the formula CHCl₃.

It is a colorless, sweet-smelling, dense liquid that is produced on a large scale as a precursor to PTFE.

Explanation

Reactivity in organic compounds is largely determined by the presence of multiple bonds.

Ethyne has a triple bond, which is the most reactive bond due to the greater electron density and availability for participation in reactions.

Explanation

Synthetic rubber like neoprene is made by the polymerization of chloroprene (C₄H₅Cl).

It is known for its resistance to oil, heat, and weathering, making it useful in industrial applications.

Explanation

Horizontal range in projectile motion is directly proportional to time of flight when speed is constant.

So, doubling the time results in double the distance covered.

Explanation

He did hard work and Succeeded

اس نے سخت محنت کی اور کامیابی حاصل کی۔

The past tense “did” requires a verb in the past tense as well.

So, "succeeded" matches “did hard work.”
