Two tubes A and B of lengths 100 cm and 50cm have radii 0.1 mm and 0.2mm respectively. If a liquid passintg though the two tubes is of mercury, determine the pressure at the junction of A and B.

Two tubes A and B of length 80 cm and 40 cm have radii 0.1 mm and 0.2 mm respectively are connected in series end to end. If a liquid passing through tow tubes is entering A at a pressure of 82 cm of mercury and leaving B at a pressure of 76 cm of mercury. Find the pressure at the junction of A and B.

Two objects A and B are of lengths 5 cm and 7 cm determined with errors 0.1 cm and 0.2 cm respectively. What is the error in determining the total length?

Two wires of the same material and same length have radii 1 mm and 2 mm respectively. Compare : their resistances,

Two objects A and B are of lengths 5 cm and 7cm determined with errors 0.1 cm and 0.2 cm respectively.What is the error in determing (a) the total length and (b) the difference in their lengths?

Two objects A and B are of lengths 5 cm and 7cm determined with errors 0.1 cm and 0.2 cm respectively.What is the error in determing (a) the total length and (b) the difference in their lengths?

Two capillary tubes of length 15 cm and 5 cm and radii 0.06 cm and 0.02 cm respectively are connected in series. If the pressure difference across the end faces is equal to pressure of 14 cm high water column then find the pressure difference across the (i) first tube and (ii) second tube

Two capillary tubes of length 15 cm and 5 cm and radii 0.06 cmand 0.02 cm respectively are connected in series. If the pressure difference across the end faces is equal to pressure of 15 cm high water column, then find the pressure difference across the (i) first tube and (ii) second tube.
