A capillary tube of radius 0.50 mm is dipped vertically in a pot of water. Find the difference between the pressure of the water in the tube 5.0 cm below the surface and the atmospheric pressure. Surface tension of water = 0.075 N/m.
The correct answer is (b) 10√2 cm
Explanation:
When the tube is inclined, the vertical rise remains the same. So the water in the inclined tube rises to 10*sec45° =10√2 cm.
The correct answer is (d) 20 cm.
Explanation:
The rise in a capillary tube is given as h = 2S.cosθ/rρg When the entire arrangement is in a freely falling elevator, the effective...
(c) The surface tension may be zero.
(d) The contact angle may be 90°.
Explanation:
The rise in a capillary tube is given as, h = 2S.cosθ/rρg The capillary tube has a certain...
The correct answer is (c) v
EXPLANATION:
When a tube of length L open at both ends has a fundamental frequency ν, then v = V/2L where V is the velocity of...
The correct answer is (4)
Explanation:
The rise in a capillary tube is given as h = 2S.cosθ/rρg When the entire arrangement is in a freely falling elevator, the effective g =...
