What minimum force must you exert to get the fridge to start moving? 660 newtons How is Mue calculated? It is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F/N, where F is the frictional force and N is the normal force. Because both F and N are measured in units of […]
How do you protect a Mosfet from a short circuit?
How do you protect a Mosfet from a short circuit? The voltage across the internal resistance can be sensed using simple comparator or even a transistor, which switches on at a voltage of around 0.5V. You can thus avoid the use of a sense resistor (shunt), which usually produces an undesirable extra voltage drop. The […]
What is the minimum energy of harmonic oscillator?
What is the minimum energy of harmonic oscillator? Classically, the lowest energy available to an oscillator is zero, which means the momentum also is zero, and the oscillator is not moving. Compare the quantum mechanical harmonic oscillator to the classical harmonic oscillator at v=1 and v=50. On what factor does the angular frequency of simple […]
What spider can kill a human?
What spider can kill a human? Phoneutria How do you kill a tarantula? If you happen to encounter the Tarantula during treatment and want it killed quickly, you could directly spray them with an aerosol insecticide such as Pyrid Aerosol. Pyrid is labeled to control spiders and delivers a quick knockdown. Are Daddy Long Legs […]
What force is used to lift a weight?
What are four things that indicate that a chemical change probably happened?
What are four things that indicate that a chemical change probably happened? There are five signs of a chemical change: Color Change. Production of an odor. Change of Temperature. Evolution of a gas (formation of bubbles) Precipitate (formation of a solid) What chemical is used in hot packs? Instant Hot and Cold Packs Commercial instant […]
Why is it possible to use physical properties to separate a mixture?
Why is it possible to use physical properties to separate a mixture? The substances in a mixture are separated by the differences in their physical properties, such as their particle size. The more different the properties are, the easier it is to separate the substances. What are three physical properties used to separate mixtures? Physical […]
Which gun has the most recoil?
Which gun has the most recoil? 950 JDJ. This gun is no joke. It uses 240 grains of powder to push a 2,400-grain bullet 2,100 fps. It bites on both ends though, generating 277 foot-pounds of recoil, or approximately 10 times as much as a 30-06. What rifle kicks the hardest? Petzal: The Hardest Kicking […]
How do rocks handle stress?
How do rocks handle stress? Rocks have three possible responses to increasing stress (illustrated in Figure below): elastic deformation: the rock returns to its original shape when the stress is removed. plastic deformation: the rock does not return to its original shape when the stress is removed. fracture: the rock breaks. What causes rocks to […]
