Explanation

• The grammatical error in the sentence is: "are".
• The subject of the sentence is "Twenty five kilometers", which is a singular noun phrase, so the verb should be singular as well. The correct verb would be "is", not "are".
• The corrected sentence would be: "Twenty five kilometers from Hala to Hyderabad is a long distance."

Explanation

• The word "avidly" means with great enthusiasm or eagerness, which fits the context of a miser gazing at a pile of gold coins.
• A miser is someone who loves money and material wealth, so it's likely they would gaze at their treasure with a strong desire and enthusiasm.
• Here's the sentence with the correct answer: The miser gazed avidly at the pile of gold coins in front of him.
  

Explanation

Kinetic energy (K) is related to momentum (p) by K = p² / 2m. If momentum increases by 20%, the new momentum p' = 1.2p.

The new kinetic energy K' = (p')² / 2m = (1.2p)² / 2m = 1.44p² / 2m = 1.44K.

The percentage increase in K.E is ((K' - K) / K) × 100 = ((1.44K - K) / K) × 100 = 44%.

Explanation

The force on a moving charge in a uniform magnetic field depends on:

• Magnetic flux density (B): The strength of the magnetic field.
• The charge on the particle (q): The amount of charge on the particle.
• The speed of the particle (v): The velocity at which the particle is moving.

The force (F) on a moving charge in a uniform magnetic field is given by the Lorentz force equation: F = q (v x B)

Where x denotes the cross product.

Explanation

The ratio of output voltage to input voltage in a transistor circuit is called the voltage gain.

It measures how much the amplifier increases the input signal voltage.

Explanation

Waves produced by oscillation of material particles require a medium to travel, called mechanical waves.

Examples include sound waves and water waves.

Explanation

A hydraulic system works on Pascal's principle, which states that pressure applied to a confined fluid is transmitted equally in all directions.

This principle is used in devices like hydraulic lifts and brakes.

Additional Information:

There have been only 7 nationwide censuses.

1. The First Census was held in Pakistan in 1951.
2. The Second Census was held in Pakistan in 1961.
3. The Third Census was held in Pakistan in 1972.
4. The Fourth Census was held in Pakistan in 1981.
5. The Fifth Census was held in Pakistan in 1998.
6. The Sixth Census was held in Pakistan in 2017.
7. The Seventh Census was held in Pakistan in 2023.

Census has been undertaken every 10 years.

It was beginning in 1872 under British viceroy.
