Answer:

Explanation:
The pump is modelled after applying Principle of Energy Conservation, whose form is:

The head associated with the pump is cleared:

Inlet and outlet velocities are found:




Now, the head associated with the pump is finally computed:


The power that pump adds to the fluid is:



Answer:
B. F. (P[1..n])
for i n down to 2
k position of the ith smallest pancake
F(k) //Flip it to the top, if the top pancake’s burned side is down
F(1)
F(i) //Flip it into place, if the top pancake’s burned side is up
F(1)
The algorithm uses at most 3n-2 flips in the worst case
Explanation:
Whenever each pancake reaches the top of the stack, it will be flipped, if necessary to ensure that its burned side is up, so that whenever it is flipped down to its proper place, its burned side is down
Answer: it called a toe box is the part of a shoe that covers and protects the toes. Toe boxes come in a variety of shapes and styles depending on the type of shoe, but they should always be wide and long enough to accommodate the toes comfortably.
