A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is : 
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
Three identical heat conducting rods are connected in series as shown in the figure. The rods on the sides have thermal conductivity 2K while that in the middle has thermal conductivity K. The left end of the combination is maintained at temperature 3T and the right end at T. The rods are thermally insulated from outside. In steady state, temperature at the left junction is \(T_1\) and that at the right junction is \(T_2\). The ratio \(T_1 / T_2\) is 
Human Digestive System is the collection of organs that are responsible for digestion. It is a vital process that is driving the human race. The digestive system includes a digestive tract, which connects organs from the mouth to the large intestine.
The Small intestine is an organ situated in the gastrointestinal tract where the food nutrients are absorbed completely. There is complete digestion of fats, proteins, and carbohydrates in the small intestine. It is the longest part of the alimentary canal ranging from 6 to 7.5 m. The small intestine of the human body is made up of three sections:
