  • what’s the difference between an N router and an N router with 1 gb with 4 ports?

    what’s the difference between an N router and an N router with 1 gb with 4 ports?

    1. Which one do I need? The regular N router is less expensive than the later, but I want to buy the right one. What is benefit to the router with 1 gb?

      Answer by Frabz
      Model and Brand?

    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

    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.
