Anne throws a 26-N rock vertically into the air from
ground level. She observed that when it is 16.0 m
above the ground, it is traveling at 25 m/s upward.
Use the work–energy theorem to find
a. the rock’s speed just as it left the ground and
b. its maximum height
Net pay is the take-home pay an employee receives after you withhold payroll deductions. You can find net pay by subtracting deductions from the gross pay.
Gross pay is an employee’s income before taking out deductions. Unless you gross-up an employee’s wages, gross pay is usually the “sticker price” you offer. You can find weekly gross pay for salaried employees by dividing their yearly salary by 52 weeks. For hourly workers, multiply the employee’s hourly pay by the number of hours worked.
How to calculate net pay
Net Pay = Gross Pay – Deductions
To get from gross to net pay, you must withhold deductions. Payroll deductions are amounts you withhold from an employee’s paycheck each pay period. There are both mandatory and voluntary deductions.Hey ;)Hope this helps...
The speed of flow in the second pipe is 0.49 m/s
In our case, this problem shows a Fluid flow. We are to solve the speed flow of fluid to the second pipe.
For the formula, we will be using the Continuity equation for Fluid flow.
is the area of the first pipe
is the speed of fluid flowing in the first pipe
is the area of the second pipe
is the speed of fluid flowing in the second pipe
For the given information
this is the radius of the first pipe
Solving the problem
Here, we focus only to solve for the speed flow of fluid in the second pipe, so we will not be needing the other information stated in the problem.
Use the continuity equation, substitute the given information.
Deriving the equation, we have:
Take note that the area for the inlet of a pipe is a circle, therefore the area of a circle is,
Substitute the area of circle in the derived formula for continuity equation, we have:
Therefore, the speed flow on the second pipe is 0.49 m/s which means that the speed flow on the second pipe slows down.

This is a strategy employed by the German army in which they use their armored division to as spearhead to their army. As a result Poland in conqured within 24 hours.
