Sinks are related to

A sphere of solid material of relative density 9 has a concentric spherical cavity and sinks in water. If te radius of the sphere be R. Then the radius of the cavity (r) will be related to R as

At what temperature should the sink be maintained to increase the efficiency by 10% ?

A cannot engine has efficiency (1)/(6) . If temperature of sink is decreased by 62^(@)C then its efficiency becomes (1)/(3) then the temperature of source and sink:

A carnot engine has efficiency 1//5 . Efficiency becomes 1//3 when temperature of sink is decreased by 50 K What is the temperature of sink ?

The sink for dead plants and animals is

Assertion : In phloem loading , food is transported to sink. Reason : Food is transported from source to sink.
