Explain briefly where the energy come from when a liquid Rises against Gravity in a capillary tube​
SSSSS [86.1K]

Answer:

Surface tension

Explanation:

When liquid rises against gravity in a capillary tube, the energy comes from surface tension.

This is because surface tension is the energy that's needed to increase the liquid surface area.

As a result of hydrogen bonding present in Water, it usually has high surface tension which makes it to possess a tough skin that can make it not to break despite high forces applied to it.

The liquid will be in contact with the capillary tube and as such experiences surface tension which in turn makes the capillary tube to experience an upward force that makes the liquid begin to rise up.

The more the liquid keeps rising, the more it gets to the point where the surface tension becomes balanced from the weight of the liquid.

A ball is hung from a rope, making a pendulum. When it is pulled 5° to the side, the restoring force is 1.0 N. What will be the
Trava [24]

Answer:

restoring force is 2 N

Explanation:

given data

angle pulled = 5°

force = 1 N

pulled = 10°

to find out

restoring force

solution

we know here force

force = m×g×sinθ     ..........1

so here θ is very small so sinθ  = θ

1 = mg(5)

mg = 1 /5     ..................2

and

now for 10 degree

we know here θ is small so sinθ  = θ

so from equation 1

force = m×g×sinθ

put equation 2 here

force = 1/5 × 10  

force = 2 N

so restoring force is 2 N

The end of a garden hose is enclosed in a mesh sphere of radius 4 cm. If the hose delivers five liters per minute, how much wate
lana [24]

Answer

0.001339 liter

Explanation:

It is given that radius = 4 cm =0.04 m

volume of sphere V=\frac{4}{3}\pi R^{3}

V=\frac{4}{3}\times 3.14\times (4\times 10^{-2})^{3}=2.674\times 10^{-4}

It is given that hose delivers five liters per minute

So the water flows through sphere per minute is given by 5×2.674×10^{-4}=0.001339 liters
