Fathometer: سمندر کی گہرائی کو جاننے والا آلہ

A fathometer is an instrument used to measure the depth of the ocean or any body of water, specifically the distance from the surface to the seabed.

It uses sound waves to calculate the depth by measuring the time it takes for the waves to return.

Galvanometer – Used to measure electric current.

Explanation

• A Periscope is an optical instrument used to observe objects that are not in direct line of sight.
• Such as monitoring the surface of the water from a submarine.

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

Water vapor is directly related to humidity, which plays a crucial role in weather prediction. 

The amount of water vapor in the air significantly influences cloud formation, precipitation, and temperature. 

Therefore, measuring water vapor content is essential for weather forecasting. 

Explanation

The final step of the scientific method is developing a conclusion.

It involves summarizing the findings, interpreting the data, and determining whether the hypothesis was supported or rejected.

The scientific method steps in order:

• Observation
• Hypothesis
• Prediction
• Research
• Experimentation
• Data Analysis
• Conclusion

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
