Humid air at 70.0 °C and 1.00 atm with 2.00 °C of superheat is fed to a condenser. Gas and liquid streams leave the condenser in equilibrium at 15.0 °C and 1.00 atm.
Use material balances to determine the following quantities for
a basis of 100.0 mol of warm, humid air fed to the
condenser.
| Mole fraction of water in the feed: | mol H2O (v) / mol |
| Mole fraction of water in the chilled air: | mol H2O (v) / mol |
| Moles of dry air in feed: | mol |
| Moles of water condensed: | mol |
| Moles of water in feed: | mol |
| Moles of water in chilled air: | mol |

Two isolated, concentric, conducting spherical shells have radii R1 = 0.450 m and R2 = 1.50 m, uniform charges q1 = +1.70 μC and q2 = +2.30 μC, and negligible thicknesses. What is the magnitude of the electric field E at radial distance (a) r = 3.40 m, (b) r = 0.840 m, and (c) r = 0.360 m? With V = 0 at infinity, what is V at (d) r = 3.40 m, (e) r = 1.50 m, (f) r = 0.840 m, (g) r = 0.450 m, (h) r = 0.360 m, and (i) r = 0?

There have been a lot of sci-fi shows recently using the "rotating space station" explanation for gravity on space stations.
After watching these videos:

I was wondering what would happen, if you were facing the direction of rotation, while standing on the "floor" of a rotating space station and tossed a ball "up". From the video it looks like the ball should land in front of you. Is this in fact what would happen and if you dropped a ball would it land behind you?

you jump from a 20 meter tall building to a 12 meter tall building you jump horozontally with a speed of 5.0 m/s.
all must be answered using ther following equations v = dx/dt; a = dv/dt; v = v0 + at; x = x0 + vot + at2/2; v2 = vo2 + 2aD
how long in seconds are you in the air?
how far apart are the two buildings assuming you jumped from the edge and landed on the edge?
what is your speed when you land?
for this question you must use the pythagrium therm

A charge of 22.0 μC is held fixed at the origin.
(A)
If a -6.00 μC charge with a mass of 3.10 g is released from rest at the position (0.925 m, 1.17 m), what is its speed when it is halfway to the origin? v=__m/s
(B) Suppose the -6.00 μC charge is released from rest at the point x = 12(0.925m) and y = 12(1.17m). When it is halfway to the origin, is its speed greater than, less than, or equal to the speed found in part A? Explain
(C)Find the speed of the charge for the situation described in part B. v=__m/s

Method: DoublyLinkedList reverse(DoublyLinkedList list) Reverse() method accepts a DoublyLinkedList of Character as the argument, reverses the elements in the list, and returns the resulting list. For example:
The given list is
'a' 'b' 'c' 'd' 'e'
The return list should be
'e' 'd' 'c' 'b' 'a'
How can we do this in Java?

Java coding:
2. Write a method which takes a list list of int , and reverse it. // recursion
3.Write a method which takes a list list of strings , and reverse it. // in different way than the previous
3. Write a two methods which take a list and find the largest integer number in it.
