Explanation

As you move from the equator towards the poles, the latitude increases (up to 90 degrees).

The further you go from the equator in any direction,

the difference between the duration of the day and night at different times of the year will be bigger.

Additional information 

there are two points in the year when day and night are approximately equal in duration. 

This is called an equinox.

The equinoxes occur around:

• March 20th-21st 
• September 22nd-23rd each year.

Explanation

Natural Gas is also known as Methane.

The principal use of methane is as a fuel.

Natural gas is a fossil fuel energy source. 

Explanation

Light Emitting Diodes are light sources that are energy efficient and can be made in a variety of colors.

Gallium is a soft, silvery metal used primarily in electronic

circuits, semiconductors, and light-emitting diodes (LEDs).

LEDs are comprised of compound semiconductor materials, which are made up of elements from group III and group V of the periodic table

Explanation

• The shielding effect decreases across a period.
• This is because the increasing nuclear charge is not fully counterbalanced by the same number of inner electrons, resulting in a weaker shielding effect.

Explanation

The energy stored in a capacitor is given by U = (1/2)CV². If the potential difference (V) is doubled:

U ∝ V²

U' ∝ (2V)² = 4V²

So, the energy stored will increase by a factor of 4.

Explanation

A thinner convex lens has a longer focal length because it bends light rays less sharply than a thicker convex lens.

A thicker convex lens has a shorter focal length as it bends light rays more strongly, bringing them to focus sooner.
