Question 24
Mensuration of SolidsA canal has rectangular cross section of width 10cm and breadth 1m. If water of uniform density 1gm cm-3 flows through it at a constant speed of 1000 mm per minute, the adjacent sea is...
- A.100 000
- B.1000 000
- C.120 000
- D.30 000
- E.350 000.
Show the answer and explanation
Answer: A (100 000)
Explanation
The cross-section is 10cm × 100cm = 1000cm² and the water moves 100cm a minute, so 100 000cm³ (100 000g) of water reaches the sea each minute.
