Explanation

The troposphere is the lowest layer of the atmosphere

It is where weather occurs and contains about 75% of the atmosphere’s mass.

The principle constituent of the atmosphere of the Earth is called Nitrogen.

Explanation

Jupiter has the shortest day of any planet in our solar system

It completes one rotation in approximately 9 hours and 56 minutes.

It is also the fastest-spinning planet in the solar system.

Explanation

Wilhelm Conrad Roentgen received the first Nobel Prize in Physics (1901).

He discovered X-rays, which revolutionized medical diagnosis.

X-rays are widely used in hospitals to detect bone fractures.

The Nobel Prizes were established by Alfred Nobel.

Explanation

The statement "To every action there is always an equal and opposite reaction" is Newton's Third Law of Motion.

This law states that for every interaction between two objects, a pair of forces is produced—these forces are equal in magnitude and opposite in direction, acting on the interacting objects. 

Explanation

This is Einstein’s famous mass-energy equivalence formula, where:  

- E = Energy  

- m = Mass  

- c = Speed of light (approximately 3 × 10⁸ m/s)

Explanation

A lightning bolt can reach about 30,000°C, while the Sun’s surface is around 5,500°C.

Thus, lightning is roughly 5 times hotter than the surface of the Sun.

Explanation

• The planet that moves around the Sun at the largest speed is Mercury
• ***
• Mercury is the fastest planet, which speeds around the sun at 47.87 km/s.
• In miles per hour, this equates to a whopping 107,082 miles per hour.

Explanation

The SI prefix Tera (T) represents 10¹².

Commonly used in measurements like terabytes (TB).

Explanation

According to Ohm’s Law, current equals voltage divided by resistance.

Unit of current is ampere (A).

Explanation

Drop forging uses a heavy hammer dropped onto the workpiece to shape it under impact.

This process improves strength and grain structure of the forged component.
