Explanation

The Gateway of Pakistan is a monument situated in Karachi, Sindh.

It symbolizes the entrance to Pakistan from the sea.

Karachi is called the "Gateway of Pakistan"

It has an ideal location and well-developed connections to form gateways region with:

• Afghanistan,
• Central Asia,
• and Western China

Additional information:

It was the first capital of Pakistan.

It is the biggest city in Pakistan.

The capital of Karachi is Sindh.

Explanation

5 is an odd number because it is not divisible by 2.

Unlike 6, 4, and 2, which are even numbers.

Explanation

The first Anglo-Sikh war was fought between the Sikh Empire and the British East India Company

Fought in 1845 and 1846

around the Ferozepur district of Punjab

Lord Harding was the Governor General during the First Anglo-Sikh War.

Additional information:

The second Anglo-Sikh war took place in 1848-1849.

The Governor General of the Second Anglo-Sikh War was Lord Dalhousie.

Explanation

Polarization is a property of transverse waves, where the direction of vibration can be oriented in various directions.

Ultrasonic waves are longitudinal waves and cannot be polarized.

Explanation

The hardest substance in the world is diamond.

Its hardness is due to the strong covalent bonding between its carbon atoms.

This making it the most resistant to scratching.

Category: Native minerals

Cleavage: 111 (perfect in four directions)

Crystal class: Hexoctahedral (m3m); H-M symbol: (4/m 3 2/m)

Crystal habit: Octahedral

Crystal system: Cubic

Dana classification: 1.3.6.1

Density: 3.5–3.53 g/cm3 3500–3530 kg/m3

Explanation

To solve this problem, we need to find the total current (I) drawn from the 220 V source.

First, let's find the current through one resistor:

I1 = V/R = 220 V / 68 ohms = 3.24 A (using Ohm's Law)

Since all resistors are identical and connected in parallel, the current through each resistor is the same:

I1 = I2 = I3 = I4 = 3.24 A

Now, we can find the total current (I) by adding the currents through each resistor:

I = I1 + I2 + I3 + I4 = 3.24 A + 3.24 A + 3.24 A + 3.24 A = 12.96 A ≈ 12.94 A

So, the correct answer is: 12.94 A

Explanation

Oil and gas are not renewable energy sources. 

They are fossil fuels that deplete over time and take millions of years to form.

The renewable energy sources are:

• Water energy
• Wind energy
• Tidal energy
• Hydroelectric
• Ocean energy
• Geothermal energy
• Biomass
• Biogas

The non-renewable energy sources are:

• Fossil fuels or Hydrocarbon fuel (Oil, Natural gas, Coal)
• Nuclear energy

Explanation

Day : Sun :: Night : Moon

Explanation

Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) applied across it, and inversely proportional to the resistance (R) of the conductor.

Mathematically, this is expressed as: I = V/R Or, V = I × R

This means that as the voltage increases, the current increases, provided the resistance remains constant.
