Consider the following pairs related to Quantum Gravity Gradiometer (...

1. QGG Technology - Measures differences in gravitational acceleration with precision up to 10^-15 m/s² over 1 meter.
This is correctly matched. Quantum Gravity Gradiometers are indeed capable of measuring very subtle variations in gravitational acceleration with high precision, such as 10^-15 m/s².
2. Application - Useful in detecting hydrocarbon deposits.
This is correctly matched. QGGs are sensitive instruments that can measure gravitational changes across locations, which can be applied in resource exploration, including detecting hydrocarbon deposits.
3. Instrument Function - Manipulates atoms at room temperature to measure gravitational forces.
This is incorrectly matched. QGGs use atoms cooled to near absolute zero, not at room temperature, to enter wave-like states and measure gravitational forces.
4. Deployment - Designed for use in high Earth orbit.
This is incorrectly matched. The QGG is intended for deployment in low Earth orbit, where it can effectively monitor changes in the Earth's mass distribution.
Thus, only pairs 1 and 2 are correctly matched, making the correct answer Option B: Only two pairs.

Consider the following pairs related to Quantum Gravity Gradiometer (...
QGG Technology
- The Quantum Gravity Gradiometer (QGG) is designed to measure differences in gravitational acceleration with exceptional precision, typically around 10^-9 m/s² rather than the stated 10^-15 m/s². This precision is generally achievable in laboratory settings over short distances, not just limited to 1 meter.
Application
- QGG technology is indeed useful in detecting hydrocarbon deposits. The variations in gravitational fields can indicate the presence of underground resources, making this application correctly matched.
Instrument Function
- The statement regarding the manipulation of atoms at room temperature is misleading. QGGs often rely on cold atom techniques to achieve the necessary sensitivity for measuring gravitational forces, rather than operating at room temperature.
Deployment
- While the QGG can be deployed in various environments, it is not specifically designed for high Earth orbit applications. Current deployments are more common in terrestrial and possibly some aerial settings, but high-orbit deployment is not a typical application.
Conclusion
Based on the evaluation:
- Correctly Matched Pairs: Only the application related to detecting hydrocarbon deposits is correct.
- Incorrect Pairs: The technology's precision, manipulation of atoms at room temperature, and deployment in high Earth orbit do not align with the current capabilities and applications of QGGs.
Thus, only two pairs are correctly matched, supporting the correct answer as option 'B'.
