Concepts of Electrostasis

why do you suppose this is so? -Outer electrons ar loosely bound with the nucleus because of their larger outstrip from the nucleus, so they can be good stripped off. In the case of the cozy electrons, the opposite is true. They ar more tightly bound because their closer to the nucleus, so they atomic number 18 more difficult to remove them. 52) You argon not harmed by contact with a aerated surface ball, even up though its voltage may be genuinely high. Is the former similar to why you are not harmed by the rater than 1 ICC sparks from a Fourth of July sparkler? Defend your resolution in terms of the energies that are involved. Yes. The reason is similar, because the amount of energies involved in both cases is very small. Chapter 23 Electric electric current 46) In the circuit shown, how do the brightnesss Of the resembling lightships compare? Which bulb draws the most current? What pass on happen if medulla A is unscrewed? If medulla ob greatata C is unscrewed? -The brightness of Bulb A and Bulb B give be the identical, while Bulb C leave behinding be twice as Bulbs A or B. Bulb C draws the most current. When Bulb A is unscrewed, Bulb C get out burn up as it had and Bulb B will not glow. If Bulb C is unscrewed, Bulb A and Bulb B will glow at the alike brightness.Chapter 24 magnetized attraction 15) One way to make a compass is to stick a modify needle into a piece of bug up and float it in a looking glass bowl full of water. The needle will align itself with the horizontal component of Earths magnetic field. Since the north pole of this compass is attracted northward, will the needle float toward the north font of the bowl? Defend your answer. -The needle will point toward the northward direction however, it will not eve towards the northward post since the forces acting on the needle balances severally other(a) Out, remaining at rest. 3) In a multitude spectrometer, ions are enjoin into a magnetic field, where they c urve and beauty a detector. If a variety of respectively unionized atoms travel at the kindred speed done the magnetic field, would you anticipate them all to be deflected by the same amount, or would different ions be stage set different amounts? Defend your answers. -Deflection of ions by magnetic fields solely depends upon their charge/ mass ratio. This is different for different ions. Chapter 25 electromagnetic Induction 2) A certain dewy-eyed earthquake detector consists of a flyspeck nook firmly anchored to Earth.Suspended inside the box is a massive magnet that is touch by unmoving coils of wire tied to the bode. Explain how this device works, applying devil of import principles of physics-?one studied in Chapter 2 and the other in this chapter. -When an earthquake occurs, stationary coils inside the detector begin to linger and a relative performance surrounded by the coils and magnets is generated. The head of the coils induces voltage into the coils. As a result, the intensity of the earthquake is recorded. ) A aloofness of wire is bent into a disagreeable loop and a magnet is plunged into it, bring on a voltage and, consequently, a current in the wire. A second space of wire, twice as long, is bent into two loops of wire, and a magnet is similarly plunged into it. double the voltage is induced, alone the current is the same as that produced in the single loop. why? -The voltage induced is directly comparative to the number Of loops Of the wire. Resistance is directly relative to the duration of the wire as long as all other parameters are constant in the formula R=PL/A.The second wire has wise the length and twice the number of turns than the first wire. 43) The metal wing of an airplane acts like a wire flying through Earths magnetic field. A voltage is induced among the wing tips, and a current flows along the wing but only for a short time. Why does the current stop even though the airplane transport use flying through Earths magnetic field? -The current stops even though the airplane continues to fly through the Earths magnetic field, because the losings which occurred when a push back operates a generator and when the voltage is stepped up by a transformer is not considered.After the close of severally cycle, the energy outputted decreases due to the losses in the motor, the generator, and the transformer. Therefore, this will stop. Chapter 32 The piece and the Quantum 6) Why does classical physics hazard that atoms should collapse? -According to classical physics, an accelerated charged particle emits radiation. An electron that is orbiting the nucleus should diversify energy and move into a handbuild path that ends at the nucleus. Therefore, atoms should collapse from a classical physics description. 28) When and where do Newtons laws of motion and quantum mechanics overlap?When the size of the carcass is very large compared to the De Brogue wavelength, the Newtons laws of motion and qu antum mechanics overlap. Chapter 33 The Atomic karyon and Radioactivity 16) Two protons in an atomic nucleus repel to each one other, but they are also attracted to each other. Explain. -Two protons in an atomic nucleus repel each other and also attract each Other, because of Coulomb Repulsion. The protons repel each other however, due to a strong nuclear force, they also attract each other. 47) Why is carbon dating ineffective in finding the ages of dinosaur bones?
