Answer:
The speed of the water flow in the pipe on the second floor is approximately 13.1 meters per second.
Explanation:
By assuming that fluid is incompressible and there are no heat and work interaction through the line of current corresponding to the pipe, we can calculate the speed of the water floor in the pipe on the second floor by Bernoulli's Principle, whose model is:
(1)
Where:
,
- Pressures of the water on the first and second floors, measured in pascals.
- Density of water, measured in kilograms per cubic meter.
,
- Speed of the water on the first and second floors, measured in meters per second.
,
- Heights of the water on the first and second floors, measured in meters.
Now we clear the final speed of the water flow:
![\frac{\rho\cdot v_{2}^{2}}{2} = P_{1}-P_{2}+\rho \cdot \left[\frac{v_{1}^{2}}{2}+g\cdot (z_{1}-z_{2}) \right]](https://tex.z-dn.net/?f=%5Cfrac%7B%5Crho%5Ccdot%20v_%7B2%7D%5E%7B2%7D%7D%7B2%7D%20%3D%20P_%7B1%7D-P_%7B2%7D%2B%5Crho%20%5Ccdot%20%5Cleft%5B%5Cfrac%7Bv_%7B1%7D%5E%7B2%7D%7D%7B2%7D%2Bg%5Ccdot%20%28z_%7B1%7D-z_%7B2%7D%29%20%5Cright%5D)
![\rho\cdot v_{2}^{2} = 2\cdot (P_{1}-P_{2})+\rho\cdot [v_{1}^{2}+2\cdot g\cdot (z_{1}-z_{2})]](https://tex.z-dn.net/?f=%5Crho%5Ccdot%20v_%7B2%7D%5E%7B2%7D%20%3D%202%5Ccdot%20%28P_%7B1%7D-P_%7B2%7D%29%2B%5Crho%5Ccdot%20%5Bv_%7B1%7D%5E%7B2%7D%2B2%5Ccdot%20g%5Ccdot%20%28z_%7B1%7D-z_%7B2%7D%29%5D)

(2)
If we know that
,
,
,
and
, then the speed of the water flow in the pipe on the second floor is:


The speed of the water flow in the pipe on the second floor is approximately 13.1 meters per second.
If you illustrate the problem, you will somewhat come up with the figure shown. The missing value is the hypotenuse of the right triangle. Using the pythagorean theorems, the value is determined to be
x = √(0.7^2 + 2.4^2)
x = 2.5 km
2.5 km is the magnitude of the distance. If you want to incorporate the displacement, the answer is reported as
2.5 km, southeast. The direction is determined from the starting point to the endpoint.
a. The risk of injury must be predictable.
b. A "breach of duty" is when a professional fails to uphold a level of care.
c. There must be a standard of care in place, and the practitioner must assume responsibility for the patient.
d. There must be a clear link between the treatment received and the harm.
<h3>What is malpractice?</h3>
Malpractice, commonly referred to as professional negligence, is defined as "an incident of carelessness or incompetence on the part of a professional" under tort law.
The following professionals might be the target of malpractice claims:
Medical professionals: If a doctor or other healthcare practitioner does not exercise the level of care and competence that a similarly situated professional in the same medical field would deliver under the circumstances, a medical malpractice claim may be made against them.
Lawyers: Failure to provide services with the amount of competence, care, and diligence that a reasonable lawyer would use in the same situation may be grounds for a legal malpractice claim.

As we know that friction force on box is given by

here we know that

here we have
m = 12 kg

so now we have

now we will have


so it required minimum 49 N(approx) force to move the block
