    2. Let N be an arbitrary integer. What is the least number of weights that can be used on
      a scale pan to weigh any integral number of pounds from 1 to N inclusive, if the weights
      can be placed in either of the scale pans?

      Answer by Brian
      The weights you need to do this are weights of powers of 3: 1,3,9,27,81,…
      If you need to measure up to N, then you will need log_3(2*N+1) weights.

    3. I know the N shell can hold a max of 32 electrons, but what about when it is just a period 4 element? I think the outermost shell of period 4 elements is the N shell, so there must be some special rule.

      Answer by sciteacher
      Each level follows the rule e=2n^2
      so level 1(n=1) e=2
      level 2(n=2) e=2*4=8
      n=3 so e=2(9)=18
      n=4 so e = 2(16)
      n=5 so e=2(25)=50 …………

    4. The original fermi level of the p and n-regions taken separately are different due to difference in concentration and type of doping. However, at the junction, the energy level diagram usually depicts a common fermi level while conduction and valency bands are displaced. How does that happen?

      Answer by epidavros
      Energy levels in materials are always relative. In other words, you can say that the conduction band is so many eV above the valence band, but it has no particularly absolute value.

      The Fermi level is simply the energy level of the topmost occupied electronic state (at T = 0). Thid once again is relative – you can say where it is with respect to say the valence band.

      Until, that is, you join the two materials. When you do this the energy of the topmost occupied state on the n side *must* be the same as that on the p side because the materials are in contact. If it were not, then electrons would flow into the lower energy states across the boundary until they were.

      Clearly, for these two levels to be the same across the boundary, the energy bands measured relative to the Fermi level must change, because the band structure must be continuous across the boundary. For this to happen the conduction and valence bands must curve. The origin of this curvature is, of course, and electical potential energy gradient across the junction. This is what gives rise to the intrinsic junction bias.

    5. What is the energy difference in Joules between the n=6 state and the n=2 state in a hydrogen atom?

      Please help me! I just want to know how to solve this problem? Thank you so much!

      Answer by Anonymous
      You have to solve certain equations.

      Start with:

      1) mv^2/r = (4*pi*epsilon)^(-1)*q^2/r^2, i.e. centripetal force is equal to coulomb’s force. Of course, we’re assuming circular orbit. Otherwise, both forces cannot be written as such. It is still a good approximation.

      2) Note that an electron in orbit does not emit electromagnetic radiation (despite centripetal acceleration). A quantum approach is needed. The explanation is that angular momentum is quantised. So use L = r x p = mvr = n(h/(2pi)), since r is orthogonal to p and where h is Planck’s constant.

      From these two facts you can discover that the energy of an electron in a hydrogen atom is equal to:
      -13.6* (1/n^2) eV. It is negative because work must be done by the electron in order to escape the pull of the proton (gravitational analogy works here).

      So the difference in energy is: -13.6/6^2 – (-13.6/2^2) eV = 13.6*(8/36) eV = 3.02 eV.

      (Note that 1 eV = 1.6 * 10^-19 J, so 3.02 eV = 4.83 * 10^-19 J)

    Can’t See My Favorite Team Locally

    Believe it or not, I am the sports fan in my family. My husband only likes to watch car races and I like to watch most other sports. I moved with him as my job moved us across the country and I can not see all of the games that my favorite home town football team plays in. I decided that we had to go with the satellite TV company that could provide us with nfl sunday ticket so that I do not have to miss any of my favorite games. My team and I have been loyal to each other, they won a Super Bowl a few years ago and I have never stopped wearing their colors, even when I knew that they were having a really tough season, it was really strained for a while. But while others put their colors down, I never did, I love them. I think it’s funny that I am the only woman that participates in the local fantasy football team online that most of the dads participate in, but I have a love for the game.

    I grew up in a house where it was only my dad to raise my brother and I for a few years so instead of wearing make up, my dad took the time to take us to different sporting events and always have it on the TV. I loved the feeling of entering a professional sporting event, seeing the excitement in my dad’s eyes, it was really special. We always liked the ability to talk about our favorite players and he still calls me today to talk about the different things going on with our favorite team. I will never be able to tell my dad how much those days meant to me, as I will always remember them.

Do You Think Direct Auto Insurance Can Save You Money?

I saved a small fortune on my car insurance by choosing to go with direct auto insurance. That is when you deal directly with the big provider of the insurance instead of going through an agent or middleman. Even the big companies will sell through intermediate insurance sellers. Your local agent may offer a deal on insurance from a big brand provider, but he will still collect a portion or fee from the provider due to selling you the policy.

Depending on who you are getting insurance from, the savings may be significant enough for you to consider not dealing with an agent or other intermediate source. However, at other times, you may actually save a little more. The insurance company may discount the same type of insurance they sell directly when they offer it through an intermediate agent. The discount offset by the portion the agent takes may still cause you to save more money than if you called them up directly. The only way to know is to ask. Go ahead and get a rate quote directly first. Then call an agent.

Be savvy when shopping for car insurance. You can literally save several hundred dollars per year for the same exact policy coverage you have now by switching to another provider. This is especially true if you have not switched or checked in a long time. Some people have the same insurance company and basically the same policy when they retire as when they bought their first car. Sometimes it is from the same provider. These are the folks that make it easy for agents to make a profit. They never even ask for a lower rate or discount. There are some major discounts and lower rates available to most everyone. However, you need to ask to find out.

Are Insurance Companies a Good Investment?

Car Insurance @ www.goodgirl.co.uk - Browse Young Driver Car Insurance ...I just got to thinking about this randomly, because I was wondering how much money you can make selling auto insurance and how you figure out auto insurance rates so that you can make good money without overcharging people. I was looking for something to invest in that would have a good return and still be safe. I know that there are a lot of risks in certain types of insurance, for example that is what insurance is about in the final analysis. The big thing is that you have to hope there are not any huge natural disasters if you are selling home insurance. A really big storm like Hurricane Katrina is going to wipe you out if you get a number of them close on the heels of one another. So it would be risky to invest in insurance companies, especially if they are deeply involved in the areas where these sorts of things happen frequently, like the Carolinas, Florida and the Gulf Coast states.

However auto insurance is a pretty predictable game it would seem. All you have to do is get your math right and find the number where you can get a large number of customers and turn a good profit. You would obviously prefer to only insure the people who will never call you up and tell you they just ran a school bus full of first graders into a ditch. You would want someone who pays his bill every month for fifty years and never has an accident. Of course that is not how it works, but if you do your math right you will get plenty of those types of people and they will keep you afloat when you have to pay claims for those who are unlucky or who are reckless.
