• 10^-3 second = Milli second (ms)
• 10^-2 second = Centi second (cs)
• 10^-1 second = Deci second (ds)

Explanation

• Ascorbic acid, also known as Vitamin C, is found in various fruits and vegetables.
• But Alma (Emblica officinalis) and citrus fruits like oranges, lemons, and grapefruits are particularly rich in it.

Explanation

• A telescope is an instrument that gathers light from distant sources.
• Such as stars, planets, galaxies, and other celestial objects.
• It allowing us to study and observe them in greater detail.

Explanation

• Red stars, also known as red dwarfs, typically have a surface temperature around 3000°C (5400°F).
• This is the coolest temperature range for stars, and it's what gives them their distinctive red color.

Explanation

• The next closest star system to Earth after the Sun is known as Alpha Centauri.
• Specifically, Proxima Centauri, which is part of the Alpha Centauri star system, is the closest individual star to Earth, located approximately 4.24 light-years away.

Explanation

Stars are massive, luminous balls of gas that are primarily composed of:

• Hydrogen (about 70%)
• Helium (about 28%)

Explanation

• Sexual reproduction involves the fusion of gametes (sperm and egg cells) from two parents of different sexes.
• It resulting in offspring with a unique combination of genetic traits.

Explanation
