A liquid contained in a 'U' -tube, when disturbed, executes _____ motion

The north pole of a very strong electromagnet is brought near the meniscus of a liquid contained in a narrow. U - tube . The liquid is seen to rise towards the north pole. This indicates that the liquid is

A liquid of density rho is filled in a U-tube, whose one end is open & at the other end a bulb is fitted whose pressure is P_(A) . Now this tube is moved horizontally with acceleration a as shown in the figure. during motion it is found that liquid in both column is at same level at equilibrium if atmospheric pressure is P_(0) then value of P_(A) is

A liquid rises in a capillary tube when the angle of contact is:

Homeostasis is disturbed when

STATEMENT-1 : Time period of the liquid executing S.H.M.in a U-tube depends on the area of cross section of U-tube. and STATEMENT-2 : The restoring force acting on liquid displaced from equilibrium position of U -tube depends on the difference in levels of liquid in the two limbs of U -tube.

Categorize the motion as periodic or oscillatory motion (i) Motion of Halley 's comet around the sun (ii) Motion osf the penedulum of a wall clock (iii) Motion of liquid n a U-tube when liquid is once compresed in one limb and then left to itself Hint : In oscallatory motion, there is to and fro motion about some mean position.

A liquid of density rho is filled in a U-tube is accelerated with an acceleration a so that the height of liquid in its two vertical arms are h_1 and h_2 as shown in the figure. If l is the length of horizontal arm of the tube, the acceleration a is
