Explanation

SpaceX uses giant "chopstick arms" on its launch tower to catch the Super Heavy booster during landing.

This system is part of its Starship program to make rocket recovery more efficient and reusable.

Explanation

 None of these options are completely incompressible.

While solids are the least compressible among the three states of matter (solid, liquid, and gas), all of them can be compressed to some degree. 

Explanation

 Wind speeds of 10–13 kilometers per hour (kph) are considered light breezes.

At this speed, wind may rustle leaves, move small branches, or flutter light flags, but it does not cause damage.

Explanation

Uranium is the most commonly used fuel in nuclear reactors due to its ability to undergo fission.

During fission, uranium atoms split to release a large amount of energy used for electricity generation.

Explanation

 A car radiator is a key component of the engine's cooling system, specifically designed to cool down the engine by transferring heat to the surrounding air. T

Explanation

Albert Einstein was a German physicist (not a physician) who gave the famous equation:

$$E = mc^2$$

Where:

• $E$ = Energy

• $m$ = Mass

• $c$ = Speed of light in a vacuum

Explanation

 A calorie is a unit of energy, specifically used to measure heat energy.

1 calorie is the amount of heat required to raise the temperature of 1 gram of water by 1°C.

In dietary terms, we use kilocalories (kcal) — where 1 kcal = 1000 calories — but it still measures energy, not diet or food itself

Explanation

• Weight (W) = 30 N

• Acceleration due to gravity (g) = 10 m/s²

• We are asked to find the mass (m).

Formula:

$$\text{Weight}=\text{Mass}\times \text{Gravity}$$$$W=m\times g$$ $$30 = m times 10 Rightarrow m = frac{30}{10} = 3 text{ kg}$$

Explanation

 The abbreviation EMF stands for electromotive force,

It is the electrical potential that drives the flow of electric charge in a circuit

 It's also sometimes referred to as voltage. 

Explanation

Three Primary Colors : Red, Yellow, Blue.

Three Secondary Colors : Orange, Green, Violet.

Six Tertiary Colors : Red-Orange, Yellow-Orange, Yellow-Green, Blue-Green, Blue-Violet, Red-Violet,

which are formed by mixing a primary with a secondary.
