Question

Sweet, sweet honey is allowed to flow out of a barrel from two spouts, as shown. Which statement correctly compares the volume flow rate out of the two spouts? The volume flow rate is the same from rach spout. The volume flow rate in the upper spout is more than 4 times greater than in the lower spout The volume flow rate in the upper spout is 4 times greater than in the lower spout The volume flow rate in the upper spout is less than 4 times greater than in the lower spout (but still greater than in the lower spout). The volume flow rate is greater from the lower spout than it is from the upper spout but less than 4 times greater. A ball is held below the surface of the water and released from rest. Which of the following statements is true? (Fg weight of the particle, Fb- buoyant force, Fv- frictional force) If the ball sinks downwards, If the ball sinks downwards, Fb > Fg. If the ball rises, Fv an Fb act in the same direction. If the ball sinks, Fv and Fg act in opposite directions. Fb is largest when the ball is initially released, then decreases as Fv increases.

Explanation / Answer

Ans ; 665 W

NOTE; we know heat transfer Q = K A (dT/dx) where A = cross sectional area

dx = width of body
for steady state heat flow Q always remains constant within body

here both bodies have same k, A (c/s area doesn't depend on length) , and consider width same for both

so Q value does not change...
