Open Question

An open ended U-tube with a uniform cross section equal to 1 cm2 and height 100 cm on both sides is mounted on a stand in the lab. The tube is filled with mercury to a height of 50 cm on both sides when the barometric pressure in the lab is 750 Torr. The left side of the tube is then sealed and the right side is connected to a vacuum pump and evacuated to a pressure of essentially zero Torr. (a) What distance in cm does the mercury level fall from its original position on the left side of the tube? Hint: Set up and solve a quadratic equation. (b) What is the final pressure in Torr of the air trapped in the left side of the tube?

SOURCE: Kohler bathtub spa does not work at all

If the air tube is still connected to the air button on the side of the tub and you are pushing it with no results then either the motor is no good, the air button is no good or the air switch in the box is no good.
process of elimination, start with the pump. take the switch off the motor or out of the box and make sure you can get the motor to come on. If the motor comes on then move to the air switch and hook it back up and see if you can blow into the air switch with a new air button or a straw and see if the switch will activate the pump. if it does then you most likely have a bad air button ($12). If you cannot get it to activate the pump then the air switch is bad ($21).

SOURCE: 2x2-3x+5=0 solving the quadratic equation

Here you are :
2X2-3x+5=0 => 4-3x+5=0; (2X2=4) => -3x+9=0; (4+5=9) => 9 = 3x; (-3x moved to the right-hand side and it became 3x) => 9/3=x; (3 moved to the right hand side, so it becomes 1/3, i.e 1/3X9= 9/3) i.e. x=9/3 => x=3
Hence x equals to 3.

You can add or remove the explanation/description, I simply add them to make you understand.
If you need help, let me know.

Good luck.

I'm removing this Whirlpool oven and want to replace it with a KitchenAid Model KEBS109BSS. Will the new KitchenAid fit in the existing cutout?

Just fill in the old opening on the top with styling to meet the height needed. If the new one is narrower in width add equally to both side styles, if its wider trim equal amounts off both sides.

How many inches equals 24mm length ?

An inch is defined as 2.54cm.
10mm = 1cm
24mm = 2.4 cm

Setting these up in a ratio we have:

1 inch x inches
--------- = ------------
2.54 cm 2.4 cm

cross-multiplying we get:

2.4 = 2.54x

Dividing both side by 2.54:

---- = x

x = 0.94488188976377952755905511811024...

Good luck.

Solid mensuration problem solving

First a square has equal sides, it means s= square root of 225 = 15.
Height of the base is equal to 15. Volume of the prism = Base area x Height = 225(15) = 3375 cu. cm x 1 liter / 1000 cu. cm = 3.375 liters
Ans = 3.375 liters

If a cube has an area of 216cm3 how do you find out its length , breadth & height

If it is a cube, length, breadth, and height are all equal. If volume (not the area) is 216 cm^3 then
V=s^3 where s is the measure of a side
s=CUBIC ROOT (216)=6
s= 6 cm

How would you represent the area of the base of the box?

Total Surface Areabox1.jpg

The total surface area is made up of three pairs of sides for a total of six sides.

We must find Areahw, which is the area of the side that is h by w.

Areahw = (h)(w)

We must find Areahl, which is the area of the side that is h by l.

Areahl = (h)(l)

We must find Areawl, which is the area of the side that is w by l.

Areawl = (w)(l)

Each of the above areas are present on two sides of the box. So, the total surface area is sum of twice each of these areas, that is:

Total Surface Area = 2(Areahw) + 2(Areahl) + 2(Areawl)


Let h = 3 cm, w = 5 cm, l = 8 cm

Areahw = (h)(w) = (3 cm)(5 cm) = 15 cm2
Areahl = (h)(l) = (3 cm)(8 cm) = 24 cm2
Areawl = (w)(l) = (5 cm)(8 cm) = 40 cm2

Total Surface Area = 2(Areahw) + 2(Areahl) + 2(Areawl)
Total Surface Area = 2(15 cm2) + 2(24 cm2) + 2(40 cm2)
Total Surface Area = 30 cm2 + 48 cm2 + 80 cm2
Total Surface Area = 158 cm2

My machine wont stop filling and wont agitate


Welcome to FixYa.

You've haven't specified if this is a new or recent install, but here`s what I find is most common when dealing with the symptom you`ve described ( as long as water isn't filling over the top )

I'd suspect the drain hose is lying down on the floor or is pushed down into the stand-pipe too far.

If the drain hose is below the water level entering the washer it will siphon out immediately. The drain hose must be above the highest point the washer has to fill, ( refer to your manual, but it is typically recommended to be about "48 to "60 in height but not more than 90" or so )

**The standpipe drain requires a minimum diameter standpipe of 2" (5 cm). The minimum carry-away capacity can be no less than 17 gal. (64 L) per minute. A 2" (5 cm) diameter to 1" (2.5 cm) diameter standpipe adapter kit is available. " The top of the standpipe must be at least 39" (99 cm) high and no higher than 96" (244 cm) from the bottom of the washer.**

Also if it is in a stand pipe insure it isn't pushed in too far, just a few inches and then secure it without completely covering over the opening or that too will cause it to siphon.

Check your drain hose. Let me know if this was indeed the case and if so please rate the solution accordingly. If not we can move forward from there.

Thank's for coming to FixYa and good luck.

How to fix fill water shooting up and over when flushing?

I don't exactly know what you mean so i will cover all the basics. The fill valve sends fills water in 2 locations. 1) the fill valve fills at the low end (from the bottom to the top) of the tank. This is the flush water level. It needs to be stopped by a float switch before the water overflows into the over flow tube.
2) the fill valve fills water via a small tube at the top of it which this tube NEEDS to be pointed into the overflow tube with a high arch. THIS water is filling your toilet bowl section to proper flushing height. If your water in your bowl does not reach proper height and someone removes this tube to aim it into the tank where the other water is stored, THEN you may have the problems you described and you will need to do several flushes to remove waste.
SO to reiterate 1) make sure your float cuts off and stops the filling cycle before the water flows into the over flow tube. This is done from 1 or 2 adjustment screws. and 2) make sure the small black tube is aimed down into the over flow tube with a good arch. The arch prevents back siphon.
