What year was Singer Model No 9323 manafactured?
The one we have was purchased in October of '93. Hope this helps!
What is the difference between a physical model and a conceptual model?
conceptual model :A conceptual model uses idea to suggest what system is or how it works.
A physical model : A physical model might be a scale model , either larger or smaller than the actual system it represents.
What is a visual aid that shows inside of a model?
A cut away diagram shows the inside of a model in a specific area of the model.
An exploded view drawing shows all the parts of a model, this is the common view enclosed in model kits.
What type of nozzles do rocket engines have?
They usually have a shaped clay nozzle formed into the end of the engine tube. This differs slightly for the intended duration of the engine.
What models can you make in physics for class 12th?
you can make a model showing torque on a circular current loop. it's very simple and you can make it yourself...
================================
Suggestion #2:
The best model would be one that has something to do with something you
learned, or something that was taught, in Physics class 12th. Somebody who
was there could tell you what was covered, and then you could model it. The
teacher would love it.
================================
Suggestion #3:

How long do you leave your paper mache in the fridge for?
Most times you don't have to put paper mache in the fridge but if you want to my best guess is probably about 30 minutes to an hour.
How do you make working model of sphygmomanometer?
A working model would serve the same function as the real thing and would have to be large enough to be used to be a working model. Therefore, if you want to make a blood pressure meter that is simply not as accurate as a real sphygmomanometer (such as for a school science project), you can use parts found at an auto parts store - such as a bicycle tire tube, a small pump, an air pressure gauge, small tubing, and the tire glue that can hold the parts together. The only thing missing is Velcro for a fastener (even supermarkets sell that today).
Where can you buy skill level 4 airfix?
Don't think they made many, but I do know of one, the A11002 De Havlliand Sea Vixen FAW.2, you can get it on Amazon
Three components of the cell theory?
-all living things are composed of cells
-cells are the basic unit of structure and function in living things
-new cells are produced from existing cells
How do you make a custom Breyer size barn?
First you take a piece of cardboard as high as you want. Hot glue 4 of them, cut out a door and paint it. Or if you want a really good one make them out of pop sticks.
Did this help? I will help more if so.
Has Lotrmaster6 committed suicide?
Nobody really knows. There are rumors, as Lotrmaster6 been a long time inactive on MiniWarGaming.com. But nobody could confirm this report. It is known that he was suffering from schizophrenia.
Sanskrit essay with Hindi meaning?
Sanskrit is a spiritual and scholarly language, and is the primary language of Hinduism. Most Sanskrit essays can be translated into Hindi.
How big is the wingspan of a B-52 Stratofortress in 1 by 72 scale?
31 inches
ANS 2 -Not being 'nit picky', but it's actually 30.8 inches. In scale model making , accuracy is everything !
Why aren't the fins in the front of a rocket?
The further forward rocket fins are, the more they tend to steer it. You could mount fins at the front, but they would have to be incredibly straight and parallel for your rocket to fly straight.
One of the worlds most famous anti aircraft missiles, the Sidewinder, has 4 small steering fins near it's nose. While it was being developed they found if these fins moved too quickly the main tube would actually twist and destroy itself !
How to make a model of a valley?
I would do this from a block of styrofoam. make each side the high ground, and carve out the valley in the centre. If there is a river or stream, lay a bed of glue or something smooth and paint it silvery. For fields get some fine sawdust and colour it with a small amount of watery green paint, then sprinkle it damp onto the styrofoam. It will stick there as it dries (if you have access to model railroad grass that's even better.)
How do you built a paper pyraimd?
You get a piece of paper and you draw a square in the middle. Then you draw a triangle connected on each side of the triangle. Cut out the shape. Along the lines fold it and tape.
Why does adding flexible springs to a ball and stick model make the model more accurate?
Because bonds can bend, stretch, and rotate without breaking.
That would make the model more accurate than the space-filling model.
How do you make a sinkhole model?
with sugar cubes as limestone and grahm crackers as top soil...pour water on top, and watch the sinkhole form
How high does a B6-2 model rocket engine fly?
Depends on the weight and streamlining of the rocket. i regularly get a B6 up to an estimated 1,500 feet.
I used to use a product called RTV to make small moulds for reproducing model ship parts in bulk. This is a 2 part,liquid silicone that sets in almost any shape you need around a'master' . After it sets, you then remove the master and can make many copies using fiberglass resin.
