The document discusses capacitor circuits and how charge is stored and released in capacitors. It poses questions about how the total charge in a capacitor remains the same after charging and how bulbs can light without a battery when a charged capacitor discharges. It asks the reader to list key findings and assumptions that make up the model of electricity based on experiments with circuits. It provides an analogy that visualizes how a capacitor stores charge like a water tower stores water pressure and then releases it later.

Consider the capacitor circuits you have studied. 9. The total amount of mobile charge in a
capacitor is the same after charging as before charging. Explain (in detail) how this is possible.
Ordinarily you think of charge flowing in a circuit when wires are connected to a battery.
Explain how it is possible for bulbs to light in a circuit in which a capacitor is discharging even
when there is no battery in the circuit. 10. why does it make sense to believe that the wire can
also be a source of moving charge? 11, From the experiments you have done and the
assumptions we have made, you now have an idea or model of the behavior of electricity. List at
least five of the findings and assumptions that make up this model 12. a. b. C. d.
Solution
Problem -9
One way to visualize the action of a capacitor is to imagine it as a water tower hooked to a
pipe. A water tower "stores" water pressure -- when the water system pumps produce
more water than a town needs, the excess is stored in the water tower. Then, at times of
high demand, the excess water flows out of the tower to keep the pressure up. A capacitor
sotres electrons in the same way, and can then release them later.

A number of monks live in a monastery and they do not communicate in any way. Monks gather just once a day in the prayer hall; there are no mirrors and monks never see their own faces. A disease is ravaging the land; its first visible sign is a mark on the forehead of the victim. The disease causes no discomfort initially but it is eventually so painful that anyone who has acquired it will immediately commit suicide. A visitor one day announces: Solution there are a lot of variations to this. unfortunately, this is a bad variation since suicide depends on their own pain threshold, not on knowing if they have the disease. There\'s one about prisoners with hats, another about an island. however, assuming they commit suicide as soon as they realize they have the mark, and they trust the visitor not to lie, i\'ll do the first one. i see the other person is marked. two possibilities: 1) i have the mark, 2) i don\'t have the mark. Suppose 2). if i dont have the mark, the other person knows he has the mark since at least one of the two has it, and he will die immediately. However, he doesn\'t commit suicide. That must mean he\'s not sure if he has the mark. The only way he\'s not sure is because I also have the mark. So I die after i realize he\'s not dying. Since I waited before dying, he knows he has the mark as well, and dies afterwards. I\'ll let you do the rest. .

A molecule or ion that donates the hydrogen in a hydrogen bond is a hydrogen bond donor A molecule or ion that binds to this hydrogen is a hydrogen bond acceptor. Specify the hydrogen bonding behavior of the 4 species below by selecting: donor for species that act as donors only acceptor for species that act as acceptors only both for species that act as both donors and acceptors neither for species that act neither as donors nor as acceptors. Hydrogen bonding behavior SiH3 ??? Hydrogen bonding behavior O: HN Hydrogen bonding behavior Hydrogen bonding behavior CH3 Solution The species which acts as a hydrogen acceptor must have a lone pair to attract the electron deficient H + ion. The species which acts as a hydrogen donor must be more electronegative than hydrogen so that bonding electrons are retained with the species and electron deficient H + ion is released. In the question, 1st species : Hydrogen bond behavior neither (no lone pair of electrons) 2nd species: Hydrogen bond behavior neither (no lone pair of electrons) 3rd species: Hydrogen bond behavior both ( Nitrogen is both acceptor & donor and oxygen is only acceptor) 4th species: Hydrogen bond behavior neither (no lone pair of electrons) .

A Martian leaves Mars in a spaceship that is heading to Venus. On the way, the spaceship passes earth with a speed v = 0.77c relative to it. Assume that the three planets do not move relative to each other during the trip. The distance between Mars and Venus is 1.20 Ã— 1011 m, as measured by a person on earth. (a) What does the Martian measure for the distance between Mars and Venus? (b) What is the time of the trip (in seconds) as measured by the Martian? Limit your answer to 2 significant digits. Solution the three planets can be thought to be stationary. distance between mass and venus=d1=1.2*10^11 m part a: using length contraction, distance measured by the martian=1.2*10^11*sqrt(1-(v/c)^2) =7.6565*10^10 m part b: time of the trip by martian=distance measured by martian/speed =7.6565*10^10/(0.77*3*10^8) =331.45 seconds .

A leadership/motivation case is provided below. The case includes important leadership issues including, but not limited to, motivation, ethical decision-making, communication, establishing an organizational culture, and managing change. The case allows students to apply what has been learned in this course about leadership and motivation. Part I Required Elements to include in the Leadership Scenario: Two important considerations: Solution Leadership Theories Trait Theory This theory postulates that people are either born or not born with the qualities that predispose them to success in leadership roles. That is, that certain inherited qualities, such as personality and cognitive ability, are what underlie effective leadership. There have been hundreds of studies to determine the most important leadership traits, and while there is always going to be some disagreement, intelligence, sociability, and drive (aka determination) are consistently cited as key qualities. Skills Theory This theory states that learned knowledge and acquired skills/abilities are significant factors in the practice of effective leadership. Skills theory by no means disavows the connection between inherited traits and the capacity to be an effective leader .

A kettle is filled with tap water and placed on a stove. The stove element is turned on. Explain why the water starts to boil after a while. Solution Water boil due a mode of transfer of heat is called convection. Explanation- Convection is mode of transfer of heat from one region to another due to bulk movement of particles of medium under the temperature difference. when stove is tuned on, heat reach from flame of stove to the container of water due to radiation. Now, heat moves from outer surface of bottom of container to inner side ( water side) due to conduction process. Since, bottom of container has the higher temperature to top surface. So, bottom part of water gains heat due to which its density decreases slighly comparision to the upper part of the water, because of which, these two parts of water ( upper and top) gain some movement. Since, any material moves from higher density to lower density under the gravity. By this way, upper part of water ( which has higher density comparision to lower) moves downward and bottom part of water moves upward taking the heat energy with themselves. Thus, a cycle forms. Bottom part moves upward taking the heat energy and top part moves downward. This process continues further. By this way, water boil when stove is turned on. .

A photographer works part-time in a shopping center, 2 hours per day, 4 days per week. On the average,six customers arrive each hour,and the arrivals appear to occur independently of one another. Twenty minutes after she arrives one day,the photographer wonders what the chances are that exactly one customer will arrive during the next 15 minutes.Find this prbability 1) if two customers just arrived within the first 20 minutes and 2)if no customers have come into the shop yet on this particular day. Solution There were a number of loose ends from the first two series, and changes in the third series, that were explained off by a text intro to the first show of Series III. This was done in the form of scrolling text across outer space, in a parody of the introductions to the Star Wars movies. The loose ends included the return of Kryten, Lister being pregnant, delivering twins Jim and Bexley, who grow up in a matter of days, then wind up in the parallel universe with the female version of Lister. The regular cast changed for Series III: Robert Llewellyn came in as Kryten, and Hattie Hayridge replaced the departing Lovett. [26] Craig Charles, Chris Barrie and Danny John-Jules remained as Lister, Rimmer and Cat respectively. [27] The character of Kryten was originally intended as a one-off appearance in the series-two episode \"Kryten\", but had returned mainly to broaden the story potential. The show was becoming difficult to write for. At the insistence of Naylor, Kryten returned to complete the team. [28] They had approached David Ross with the intention of bringing him back to play the regular role of Kryten. Ross, however, was in a stage play Flea In Her Ear and was not available, so they went to see Robert Llewellyn. Llewellyn was also in a stage show called Mammon: Robot Born of Woman , playing a robot. They saw his performance and were impressedhis book actually began with another book .

Consider the plane R 2 and consider any two lines that pass through the origin. Are these lines subspaces of the plane? Are they isomorphic? Are they \"the same\"? Clearly the \"look different\", but mathematically, do they behave the same structurally? Thank you, Please show work Solution 1 . lines cannot be subspaces , they can be made boundaries of a sub space,In rough terms we can call them a subspaces of zero area. 2 . for two graphs to be isomorphic,the relation between output of one graph and input of the other graph must be a bijection.in easy terms for every value of input taken for 2nd graph from the output values of the first, there should be a unique output.as it is a real plane and both are straight lines passiing through orign,both lines are isomorphic 3 . They are absolutely not same but the behaviour will same as i)they have no intercepts ii) they have constant slopes these two propertes make them structurally similar .
