The rocket's acceleration is created by the net force acting on it. There are three forces acting on the rocket: the thrust provided by the engines, gravity or weight, and air resistance. The acceleration is inversely proportional to the rocket's mass. This is Newton's Second Law: (acceleration) = (net force) / (mass) We need to think about the direction of the forces. The thrust acts upward (call this positive), and both gravity and air resistance acts downward (call these negative). So we get (acceleration) = (thrust - weight - air resistance) / mass A typical rocket engine will provide constant thrust as long as the fuel lasts. But as the engine consumes fuel, expelling the exhaust products out the back of the rocket, the rocket's mass decreases. This tends to increase the rocket's acceleration since acceleration is inversely proportional to the mass. In addition to the decreasing mass, the rocket's weight decreases as it moves farther from the center of the Earth--- this effect is described by Newton's Law of Gravity. The rocket's decreasing weight tends to increase its upward acceleration. The action of air resistance is more complicated, and ordinarily we ignore air resistance in simple models just to avoid the complication air resistance gives to the problem. In the standard air resistance model, air resistance scales with the square of the rocket's speed and the air density. The rocket is moving faster and faster, but the air density is also decreasing as it rises through the atmosphere. I think we can safely say the air resistance force decreases as the rocket gains altitude, but a detailed answer illustrating precisely how this force changes would require a numerical simulation. Hope this helps!

There are 676.
The three-letter abbreviation for Australia is AUS.
Total number of choices for 3 initials = 263 Number with all three different = 26*25*24 (assuming ABC is not the same as ACB) So number with two or three alike = Total - number with no matches = 263 - 26*25*24 = 17576 - 15600 = 1976

The three basic parts of a rocket are the rocket engine, which provides thrust for liftoff, the propellant tanks, which store the fuel and oxidizer, and the payload, which is the cargo the rocket is carrying into space.
The three types of rocket fuels are liquid rocket fuel, solid rocket fuel, and hybrid rocket fuel. Liquid rocket fuel consists of liquid components that are combined and ignited to produce thrust. Solid rocket fuel is a mixture of solid components that burns to produce thrust. Hybrid rocket fuel combines elements of both liquid and solid rocket fuels.
A water rocket should probably have three to four fins.
to simplify the design of the rocket.
Cinemassacre's Monster Madness - 2007 Ghidrah the Three Headed Monster 2-5 was released on: USA: 7 October 2008
If you have a level one monster academy, you will be able to upgrade all of your monsters to level two. But to upgrade your monsters to level three, you must first upgrade your monster academy to level two. Then, once you have upgraded your monsters to level three, you must upgrade your monster academy to level three. I.e, if you have a level two monster academy and your pokeys are upgraded to level three, if you want to upgrade your pokeys to level four, you must upgrade your monster academy to level three.
