What happens when satellites crash? The Short Answer: Two things can happen to old satellites: For the closer satellites, engineers will use its last bit of fuel to slow it down so it will fall out of orbit and burn up in the atmosphere. Further satellites are instead sent even farther away from Earth. How […]

What factors influence potential and kinetic energy? Since the state of motion of an object can change with time, the kinetic energy of an object can also change with time. The amount of Kinetic Energy that an object possesses is dependent on two factors: mass and velocity. Both of these factors are directly proportional to […]

What is a high resistance wire? Resistance wire is used to control the amount of current in a circuit. High resistivity is better since a shorter wire can then be used. When it is used for heating elements for applications such as electric heaters and toasters, high resistivity and oxidation resistance is important. What’s the […]

How does a roller coaster go up a hill? A roller coaster does not have an engine to generate energy. The climb up the first hill is accomplished by a lift or cable that pulls the train up. The higher the hill the coaster is coming down, the more kinetic energy is available to push […]

Are there any full blooded aboriginal peoples left 2020? Yes there are still some although not many. They are almost extinct. There are 5000 of them left. There are 468000 Aboriginals in total in Australia in which 99 percent of them are mixed blooded and 1 percent of them are full blooded. What is wrong […]

What are the 12 meridians? Since then, acupuncture has become the most popular alternative medicine in the US. The Heart Meridian. The Lung Meridian. The Stomach Meridian. The Kidney Meridian. The Large Intestine Meridian. The Small Intestine Meridian. The Liver Meridian. The Bladder Meridian. What does Prime Meridian mean? The prime meridian is the line […]

How do you calculate sound pressure? Sound pressure level (SPL) calculator – formula & step by step calculation to measure the logarithmic RMS value of the sound or acoustic pressure caused by the sound wave relative to a reference value in decibels. SPL (dB) = 10 log10(p2/po2). How do you convert pressure to dB? Sound […]

How do you calculate isothermal compression? It is also worth noting that for ideal gases, if the temperature is held constant, the internal energy of the system also is constant, and so ΔU = 0. Since the First Law of Thermodynamics states that ΔU = Q + W (IUPAC convention), it follows that Q = […]

What is the difference between SAR and radar? SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional beam-scanning radars. Additionally, SAR has the property of having larger apertures for more distant objects, allowing consistent spatial resolution over a range of viewing distances. What is the […]

What is a blue black deck called? Dimir What is a multicolored spell? Multicolored spells are spells that are more than 1 color. Being *a* color is not enough; it would need to be something like Utter End for the Filter to apply. What is Blue White called in MTG? Set details Shard Name Primary […]
