Generally, A vehicle in a higher orbit will attach a tether to a lower vehicle. The difference in velocity and perturbing accelerations will cause both vehicles to swing along an arc defined by the joining tether. If the lower object is released at the point of greatest retrograde velocity, Then lower its perigee while the apogee will be raised for the higher object. Conceptually, the momentum exchange good for ADR activities. In theoretical need shows that a 10 km tether would be required to lower orbit altitude by 100 km.
Basically the uranium releases enough heat to boil the water to 300ºC. We all know that water turns to vapour at 100ºC so how do we keep it in liquid form so it can turn the turbines and generate electricity? Answer: Keep the whole chamber at an extremely high pressure so the water is in essence ‘squeezed’ into staying as a liquid. This chamber needs a coolant around it to stop the plant from overheating. Now imagine what happens when there is a disaster, or a power cut and the this cooling system stops working….300ºC, high pressure chamber, radioactive source…Fukushima.
Even taking into account the weight of the rubber balloon, the helium balloon floats on the air and is less dense than the air. The air filled balloon sinks because the weight of the rubber balloon makes is a bit heavier and far denser. Hydrogen balloon: Compare the densities of hydrogen, helium, and air to estimate what will happen to a hydrogen balloon. In the hydrogen balloon demonstration usually not enough hydrogen fills the balloon to conquer the weight of the balloon. Sometimes you can almost see
After crafting and obtaining these pieces, the rest of the rocket production is left to one’s own creative style. In the end, if all the necessary parts are accurately constructed, and with a spice of creativity, the laws of physics will ensure a successful launch. The reasons behind the bottle rocket’s ability to launch and fly high are the laws of physics, specifically Newton’s Laws of Motion. His third law of motion states that for every action there is always an equal and opposite reaction, and
(V1 / T1) = (V2 / T2). This relationship can be observed within a balloon placed within ice water and boiling water. Within the boiling water, the molecules within the balloon are moving faster, revealing high kinetic energy and a larger volume than the molecules within the balloon of the ice water. The line of best fit reveals the y-intercept temperature as -10.61 K. This temperature represents when volume is also equal to zero. Absolute zero is when temperature is 0 K, leading to pressure and volume to also equal zero.
The potential energy, or the Elastic energy in the balloon begins at a high value then is lowered to a low value as the balloon is popped. The second law of thermodynamics determines that the energy flow cannot occur from low to high without work being present. For example, as the balloon is popped, the kinetic energy of the system then increases, which without work is not possible. However, there is work done to the balloon. The act of a human popping the balloon is work and requires the human to convert chemical energy into work.
The substance undergoes a process called supercritical drying where the liquid is removed from the gel leaving the linked silica network without causing the material to collapse. As aerogel is made up of 95% to 99% air, it is very porous. Its pores are exceptionally minuscule preventing air particles from colliding with another and stopping gas phase conduction, and with that heat energy loss. To increase aerogel insulations effectiveness more materials are added, such as carbon. Aerogel insulation significantly reduces convection, conduction and radiation, which are the three procedures of heat transfer ("Low Energy House - What is Aerogel Insulation?").
Sir Frank Whittle is credited for inventing the turbo-jet engine. “A jet engine uses the same scientific principle as a car engine: it burns fuel with air (in a chemical reaction called combustion) to release energy that powers a plane, vehicle, or other machine. But instead of using cylinders that go through four steps in turn, it uses a long metal tube that carries out the same four steps in a straight-line sequence—a kind of thrust-making production line” (“ExplainThatStuff.com”). The car engine is not as powerful or fast as the jet engine, but the jet engine is for traveling a long distance in a short amount of time; the car engine is designed for traveling a shorter distance in a similar slot of time. Both engines were designed to get you from point A to point
How was the ship rotating in space if there is no air in space? The rockets could have potentially caused the rotation, but at the same time, the ship was being cooled with nitrogen that was stable enough not to freeze it when it was time to launch, The ship was kept in a pod right up until liftoff, this was to prevent shaking,shuddering, and potential failure of Apollo 11. But at the same time it puts a question into my head: If The ship was being cooled with nitrogen, How did the rocket fuel not get frozen and end up burning out too quickly? This is answered by the fact of matter, the gasoline was at the same time cooling and heating up, The metal was causing it to be trapped and the sun was heating the metal trapping the heat inside, mixed with the nitrogen, This would equal into having a steady flow of gasoline throughout the launch to guarantee a durable time to have gasoline for both the
In order to calculate for the molar mass the temperature, volume, mass, and pressure was measured. The ideal gas law equation was derived in order to express the relationship between the molar mass, mass of the condensate, temperature, pressure, and volume. A 125-mL Erlenmeyer flask was added with an unknown liquid, was capped with an aluminum foil with a tiny hole and was heated in boiling water in a beaker until the liquid in the flask is vaporized. The flask was cooled until condensate is observed. After cooling, the flask was weighed in an analytical balance.
Genius When using gas in the egg drop challenge, it spreads the amount of energy transferred from the ground to the egg. Making the energy from the ground to the egg less, because if you look closely at a balloon filled with air. When it hits the ground, the gas in the balloon spreads out inside the balloon, and then contracts back. The solid object (the egg) on top of the balloon will sink into the balloon, because it’s a solid and heavier than the gas in the balloon. Let’s say you have an egg that weighs about one pound, you have to build a sculpture that slows down something moving at 9.8 meters per second.
The release of heat makes it an exothermic reaction. The new and smaller compounds are mostly in gas form. Once these gases build up in the can, it then eventually escapes through the bottom of the can to propel the rocket upwards. As you can see the data table above shows the qualitative data about what material the rockets were made out of, as well as if they succeeded in reaching the height that was needed in order to succeed. Some quantitative data is missing due to the fact that they did not shoot the rocket the first trial not giving us a number for that
For example, it says in the book, “‘What makes a rocket fly?’ ‘Newton’s third law. For every action, there is an equal and opposite reaction.’” It also says, “‘[The nozzle is] designed to convert slow-moving, high-pressure gasses into a stream of low-pressure, high-velocity gasses.’” This book not only entertains
The Law of Inertia is the net force of the object greater than the gravity pulling it down and it will stay at rest until something happens(Getting a Bang Out of Breath Spray). It stays at rest until an unbalanced force makes the object go into motion( Getting a Bang Out of Breath Spray.) Is it true that when the kinetic energy of a canister launched straight up is at its maximum, the potential energy is near zero, and vice versa. It is false, the potential energy reaches its maximum during flight but returns to 0 when the canister reaches the ground(Getting a Bang Out of Breath Spray). What would a graph of pressure in the canister vs. time after spark ignition look like?
“Hydrogen bomb or H-bomb, is a weapon deriving a large portion of its energy from the nuclear fusion of hydrogen isotopes. In an atomic bomb, uranium or plutonium is split into lighter elements that together weigh less than the original atoms, the remainder of the mass appearing as energy. Unlike this fission bomb, the hydrogen bomb functions by the fusion, or joining together, of lighter elements into heavier elements. The end product again weighs less than its components, the difference once more appearing as energy. Because extremely high temperatures are required in order to initiate fusion reactions, the hydrogen bomb is also known as a thermonuclear bomb.” The hydrogen bomb is the most powerful bomb ever created.
