Explanation

When air increases, more molecules exert force on the surface.

This greater force causes atmospheric pressure to rise.

Explanation

Parsec (per sec) is an astronomical unit used to measure large distances between stars or galaxies.

1 parsec ≈ 3.26 light years.

Explanation

Explanation

Power = Force • Velocity (dot product),  

This gives instantaneous power, measuring how much work is done per unit time.

Explanation

When the volume of a gas is held constant, increasing the temperature causes the pressure to increase,

While decreasing the temperature causes the pressure to decrease.

This direct relationship is described by Gay-Lussac's Law, which states that for a fixed volume,

The ratio of pressure to absolute temperature is constant.

Explanation

Unit of torque: newton metre (N m)

Explanation

The SI unit of radioactivity is becquerel (Bq).

Curie is a non-SI unit, with 1 curie equal to 37 billion Bq.

Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration)

It is the process by which an unstable atomic nucleus loses energy by radiation.

Three of the most common types of decay are:

• Alpha
• Beta
• Gamma decay

Explanation

The normal body temperature is: 37°C

The average normal body temperature is generally accepted as 98.6°F (37°C).

A temperature over 100.4°F (38°C) means you have a fever.

Additional Information:

Hypothermia is the term used for temperature less than 36.50°C

Mild Pyrexia is the term used for temperature (99-100°F)

Moderate Pyrexia is the term used for temperature (100-103°F)

Severe Pyrexia is the term used for temperature (103-105°F)

Explanation

Summer Solstice happens once every year. 

Summer Solstice is on 21 June, also known as the longest day of the year.

22 December night is the longest night of the year.
