Practice questions without fighting the page.

"Prevail upon" means to convince or persuade someone through argument, pleading, or persistent effort.

In Quantum computing, "Qubits" are used to represent data as they can exist in multiple states simultaneously due to the principles of quantum superposition.

<b>Correct answer: D — At poles</b> <ul> <li>Key concept: Gravity varies with latitude because Earth is an oblate spheroid and rotation adds centrifugal force that reduces effective gravity more at the equator.</li> <li>Reason: At the poles, centrifugal force is minimal and radius is smallest, so the gravitational acceleration (g) is strongest.</li> <li>Formula note (conceptual): Effective gravity g_eff ≈ g − ω^2R cos^2(latitude); maximum where the centrifugal term is smallest (poles).</li> <li>Exam tip: Remember g is largest where rotation has least effect; smallest at equator.</li> <li>Why others are incorrect: Equator and tropics have greater centrifugal reduction; poles do not.</li> </ul>
