4. Water flows through a non-uniform tube of area of cross sections A, B.
and C whose values are 25, 15 and 35 cm² respectively. The ratio of the
velocities of water at the sections A, B and C is
1) 5:3:7
2) 7:3:5
3 ) 21:35: 15
4) 1: 1:1

Answer:
7:3:5
Explanation:
By the Equation A1V1=A2V2
Since A1V1 for all the three cross sections are same, So V2= A1V1/A2
So we take ratio of all the three velocities= 1/25:1/15:1/35= 7:3:5
Answer:
the ans. is
2) 7:3:5
