Question

Match column I with column II :

List I	List II
Magnus energy	Pascal's Law
Loss of Energy	Archimedes' principle
Pressure is same at same level in a liquid	Viscous force
Hydraulic Machines	Lifting of asbestos roofs

• A. B$\to$4, C$\to$2, D$\to$1, A$\to$1
• B. A$\to$4, B$\to$3, C$\to$1, D$\to$1
• C. C$\to$4, A$\to$2, B$\to$1, D$\to$1
• D. D$\to$4, A$\to$2, B$\to$1, C$\to$1

Answer 1

Answer: (B)

A$\to$4, B$\to$3, C$\to$1, D$\to$1

Magnus effect talks of difference in pressure caused due to difference in velocity to lift a structure. Lifting of asbestos roofs during cyclonic storms in based on this phenomenon. So, $A\to 4$
Viscous force is wet friction and brings loss in internal energy. So, $B\to 3$
At the same level in the same liquid in a container, the pressure is the same according to Pascal's law. So, $C\to 1$
Hydraulic machines use the idea of Pascal's law to transfer equal pressure in all directions from the free surface where it is applied. So, $D\to 1$
