Question

6. I force 200 cm^3 of water through a slanted pipe whose cross-sectional area is
constant at 10 cm^2. The pressure at the pipe inlet is 150 N/cm^2 higher than at its
outlet. How much work have I done on the system?
a. 150 J
b. 300 J
c. 3000J
d. It depends on the height difference at the ends of the pipe​

Answer 1

Answer:

It depends on the height difference at the ends of the pipe

Answer 2

I force 200 cm^3 of water through a slanted pipe Answer is D . It depends on the height difference at the ends of the pipe

1) .   If you push something perpendicular to the gravity you don't do any work .

2).  For work to be done by Me , I should force water in a direction against Gravitation  . So work depends on height difference .

3). And the other thing is we don't need to push anything in direction of gravitational force
