* if air is blown with a speed of 15 m/sec across the top of one side of a u-tube containing water, what will be the difference
1 answer:
if air is blown with a speed of 15 m/sec across the top of one side of a u-tube containing water, the difference between the water levels on the two sides is 1.3 cm.
<h3>What is density?</h3>The density is the ratio of the mass and volume of the particular object or liquid.
Applying the Bernoulli's equation across the ends of the tube A and B, we have
Substituting ρ = 1.2 , v = 15 and
In the left limb,
In the right limb,
The pressure at C and D are same.
Substituting from the above equations , we have,
h = -1.3 cm
The height to the left limb is greater.
The difference between the water levels on the two sides is 1.3 cm.

The most effective forces on the object are the backward force of air resistance relatively very small in magnitude, and the force of gravity. Because the spiral path of the satellite is not perpendicular to the gravitational force, one element of the gravitational force pulls forward. at the satellite to do fantastic work & make its speed increase.
<h3>What is called gravitational force?</h3>Gravity, additionally referred to as gravitation, is a force that exists amongst all material gadgets withinside the universe. For any objects or particles having nonzero mass, the force of gravity tends to draw them in the direction of each other. Gravity operates on objects of all sizes, from subatomic particles to clusters of galaxies.
