Indeed they do! There are a few primary forces that affect a rocket's flight, and one of those forces is drag. Aerodynamics is basically how drag affects an object in motion, and making something "more aerodynamic" means building it in such a way that it has less drag. The less drag something experiences, the faster (and in the case of model rockets, higher) it can go.

You could use tap pressure, a connecting pipe and a balloon.

The best glues for dioramas are Super glue, white glue and TiteBond ll. I use both for different purposes, the TiteBond for attaching parts to the base and Super for building trees etc. and the white glue for attaching grass.

its because it doesnot provide flexibility to the constructed models in which they are going to be manipulated after the rigging process..

The effect is the same as when you have a thin film of oil on water. You can also use a hose with a very fine spray mist, pointed into the air on a sunny day and see a real rainbow if you stand in the right place.

The air that you exhale contains water vapour. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapour in the air.(the maximum amount of water vapour that the air can hold at that temperature) The colder the air, the less water vapour it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapour. When the air becomes saturated, (relative humidity is 100%), the extra water vapour will condense, allowing you to see your breathe on cold days.

Most objects do not give off their own light; it has to reflect light to be seen. Shine a laser onto a mirror and hold a piece of paper up in front of the mirror, watch how the rays bounce from the laser to the mirror and off onto the paper.

You glue all the sticks together and cut the edges to make them stand. make sure to put sticks all around. then you can design it.

1.(a + b)²

This is easy. On a piece of paper, make a square of length (a + b) [Choose a and b as per your wish t be any two lengths].Its area represents (a + b)². Make another square of side a, and another of side b.

Make a rectangle of side 2a and b or 2b and a, whichever is convenient.

Put the side a square, side b square and the rectangle on the bigger square of side (a + b). You can show that this fits perfectly, thus proving the identity.

First take a bottle of water and put a small motor inside it. then take a tube and paste it on the top of the bottle after that make a slide from the tube that help it to come down easily. Now yourDAM is ready

see along time ago before dinosaurs walked the earth.

the end.

i think you need a light bulb a clear fruit pot a pringle pot containing the lid,screawed up news paper for the rocks around the light house and more news paper to paper macha the pringle pot but not the lid, a peice of coloured card to stick your rocks and light house too,you may also need a babys bottle teet for the top of the light house also you may need pipe cleaner and lolly pop sticks for the balcony bars where you would stand to clean the fruit pot so that the sailers can see that there going to crash and any kind of thing for the platform of the balcony thats it for now hope you enjoy trying to fid out which bit goes where.

There is no perfect way, but gold with a tiny dash of red comes close.

There are several ways one can make a working model of an earthquake. You can use an empty 2 liter bottle, clay, baking soda, and dish detergent to make a working earthquake.

trasport and communication

Carefully cut out required decal. Soak in a dish of water until decal separates from backing card. Apply decal to desired area (preferably with tweezers). Gently remove air bubbles from behind decal using a soft cloth. Allow to dry.

a wax person is alike from a real person because a person can breathe

models may look and act like the real thing but they are not...they do not function the same way as the real one does.models may look and act like the real thing but they are not...they do not function the same way as the real one does.

There are a few ways to make an English working model. The exact model details depend on the type of English working model you want.

It can be, but I would upgrade it with some tape and filling just in the plug to water proof it. If its a brushed motor do NOT run in in mud or water. That just ruins the brushes then it won't work. Nor Brushless don't run it in it rather, or have fun buying another VXL system.

To make a working model on energy resource and conservation there are several steps. The first step is to make a propane wheel. The second step in this model would be to attach piping to six containers and create a circle with these containers. The bottom of all six containers should be submersed in water. Lastly, fill all of the containers with propane

whats the answer

its easy buy a clock from a stationery shop. the easiest and the simplest of all.
