Assertion (A): The Coriolis force cannot change the speed of a parcel of air.
Reason (R): It always acts at right angles to the velocity of the parcel.
Select the correct answer from the options below.
Answer: B
A force perpendicular to the velocity has no component along the direction of motion, so its rate of doing work is zero and the kinetic energy of the parcel is unchanged. The reason is therefore exactly the explanation of the assertion. This is why Coriolis can organise a circulation but never energise one, and why the energy budget of a weather system is written in terms of pressure work and buoyancy alone.
