Folding the paper will create two halves of the circular cut-out.

As you approach the North Pole, the compass needle starts to point downwards due to the magnetic field lines converging.

Semantic memory deals with facts and concepts, while figural memory relates to images and visual information.

The angle between Magnetic North and True North is known as Declination.

A circuit breaker is analogous to a dam, as it stops the flow of electricity when it exceeds a certain limit, preventing damage.

Alternating current (AC) is analogous to a river that flows back and forth, as the direction of current changes periodically.

Voltage can be compared to the height of a water tank, as it determines the potential energy available to push the current through the circuit.

A strong magnetic field can cause deviation in the compass reading, leading to inaccuracies.

Chromatography offers high resolution, allowing for the effective separation and identification of complex mixtures.

The mirror image is obtained by flipping the figure horizontally.

The mirror image of the number '6' is '9'.

The mirror image is obtained by flipping the shape horizontally.

The pattern is that each number is multiplied by 2. Thus, 20 * 2 = 40.

The series follows an alphabetical order, so the next figure is D.

The pattern is that each letter is two places ahead in the alphabet. G + 2 = I.

The series consists of every second letter in the alphabet: D, F, H, J, L.

The series is the Fibonacci sequence where each number is the sum of the two preceding ones. The next number is 3 + 5 = 8.

The differences are 1, 2, 3, 4, which increase by 1 each time. 11 + 3 = 14.

The series consists of perfect squares: 1^2, 2^2, 3^2, 4^2. The next number is 5^2 = 25.

The series increases by 10 each time: 10, 20, 30, 40, next is 50.

The series adds 10, 10, and then 20. The next addition is 30, so 50 + 30 = 80.

The series increases by 12 each time. The next number is 48 + 12 = 60.

The series is a geometric progression where each number is multiplied by 2. Therefore, 16 * 2 = 32.

The differences between the numbers are 3, 5, 7, which increase by 2 each time. The next difference is 9, so 18 + 9 = 27.

The series is a geometric progression where each number is multiplied by 2. The next number is 40 * 2 = 80.

The series is a geometric progression where each number is multiplied by 2. The next number is 56 * 2 = 112.

Shape B follows the sequence logically based on the previous shapes.

The differences are 3, 5, 7, which increase by 2 each time. 18 + 8 = 26.

These are prime numbers: 2, 3, 5, 7, next is 11.

Insulators are materials that prevent the flow of electricity.
