  • U-tube Manometer?

    I want to determine the density of oil at different temperatures below 100 deg. Celsius.

    using water as a gage fluid, is it recommendable to use an open-type U-tube manometer?

    if not.. Please suggest a quite descent experiment I could do using a U-tube manometer.  Thanks!..

  • Question on quantum photon energy?

    I have an example,

    In a microwave oven that producing 2.54Ghz @ 700 W of power.

    If we calculate the photon energy E = hv

    E = (6.62 x 10^-34) * (2.54 x 10^ 9)

    E = 1 . 68 x 10^ -24 J

    If we divide the power 700 W to the photon energy,

    700 / E

    We'll have a value of

    = 4 . 159 x 10 ^ 26

    Question 1 : is this the total number of microwave photons?

    Question 2 : is it also the total number of electrons? If i am thinking (please correct me if Im wrong) that each photon is produced by an electron inside the magnetron? With a cyclotron frequency same as the produced microwave frequency (2.54 Ghz)?..

    In-depth explanations are more appreciated.. thank you..

    How can I see the directory on the folders inside the disk (let say Disk C) if the have spaces in their names?

    example.. Program Files

    so I would write :

    DIR C:\Program Files

    i already done that, but the computer says that File not found. But when I've tried it with folders that their names doesn't contain spaces, it works.. What will I do?

    thanks a lot.. =)

  • DIRECT CURRENT QUESTION...?

    Example.. I have several voltage sources, such as batteries.. They have identical potential difference, let say, 3V (of course, they are not precisely identical).. How can I connect them without increasing its total output voltage? Let say, I want to maintain 3V output voltage of the connected batteries and I just intended to increase the total output energy capacity..

    How can I connect them? I've already asked this question but somebody said that the higher voltage battery can drive that lower voltage one and that's a bit dangerous..

    What should I do? any suggestions please?.. if you can make your answer a bit scientific approach, that would be great.. thanks..

  • SELECTION FOR MASTERAL COURSE.. please help me...?

    I'm a mechanical engineer. I love physics and I also want to be a physicist. I am confused on what to take on my masters degree, physics or engineering (I want to focus on energy production and I've chosen MS Energy Engineering)? Do you think I can still contribute on physics even though I'm an engineer and just study physics myself? or I should pursue the MS Physics course even though it would take a long time? If you have any suggestions and other commentaries, I am happy to read it.. thank you.. I wish you could help me..
