Explanation

The young of a lion is called a cub.

A lion cub stays with its mother for about two years, learning how to hunt from her as it grows into an adult lion. 

The term "cub" is also used for the young of other big cats, such as tigers and bears. 

Explanation

Aslam and Faisal go to school.

- The subject "Aslam and Faisal" is plural (two people).

- With plural subjects, we use the base form of the verb without "s" in the present simple tense.

- Therefore, we say: go (not "goes"). 

Explanation

Oman is an independent sovereign nation.

It is one of the countries that border the UAE.

The United Arab Emirates consists of seven independent states:

1. Abu Dhabi,
2. Dubai
3. Sharjah
4. Umm al-Qaiwain
5. Fujairah
6. Ajman
7. Ras al-Khaimah.

Explanation

The SI unit for electromotive force (EMF) is the Volt (symbol: V).

One volt represents one joule of energy provided per coulomb of electric charge. 

Explanation

• Wavelength is the distance between two consecutive points on a wave that are in phase.
• It is typically denoted by the symbol λ (lambda).

Key Points:

• Time period (T) is the time taken by the wave to complete one oscillation.
• Frequency (f) is the number of oscillations per unit time.
• Amplitude (A) is the maximum displacement of the wave from its equilibrium position.

Explanation

A wave that results from simple harmonic motion (SHM) is called a sine wave, or a sinusoidal wave.

This is because the pattern of displacement, velocity, and acceleration in SHM is represented by a sine function over time. 

Explanation

The frequency of AC (Alternating Current) supply in Pakistan is typically 50 Hertz (Hz).

AC electricity alternates back and forth in a direction 50 times per second

Explanation

In simple harmonic motion (S.H.M), the restoring force is minimum at Mean position. 

The restoring force is directly proportional to the displacement from the mean position.

At the mean position, the displacement is zero, meaning the restoring force is also zero at that point. 

Explanation

Velocity is a vector quantity. 

A vector quantity has both magnitude and direction.

Velocity, which describes the rate of change of position in a specific direction, needs both a magnitude (speed) and a direction to be fully defined. 

Vector Quantities: Velocity, momentum, torque, acceleration.

Scalar Quantities: Work, distance, speed, mass.

Explanation

(1/3) × (1/2) = 1/6
