A quadrilateral is a four-sided polygon that may be classified as: trapezoid, rectangle, square, rhombus, etc. This classification is based on the measurement of the four angles, the four sides, and their being parallel. Unfortunately though, I think you missed to include here the diagram that we are about to classify.
The first thing you should know is that the friction force is equal to the coefficient of friction due to normal force.
Therefore, clearing the normal force we have:
The friction is 565N.
(565 / 0.8) = 706.25N. weight.
here we know that volume of the drop is given as



now the mass of the drop is given as


now the net buoyancy force on the drop is given as



now the net force on the drop is


now acceleration of the drop is given as


now the speed of the drop is given as



Answer:
An independent variable is the variable in an experiment that is changed. A dependent variable is the resulting variable that "depends" on the changes made to the independent variable. Controlled variables are all of the other variables that are kept the same between all changes made to the experiment. You would graph the independent variable and dependent variable. The independent variable will be found on the x-axis while the dependent variable can be found on the y-axis.
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.
