Hello. I am currently a high school student in South Korea. I was assigned to conduct a physics research project in school, but I really cannot even get started on solving it and I was wondering if you could help me.
The question is: Investigate the various forces involved when you try to separate two sheets of glass separated by a thin layer of water.
So far, I’ve found that two main forces will work to make separating the glass harder. First is the fact that you have to break the bonds within the film of water to separate the two sheets, and the second is that sandwiching water between the two sheets creates a pseudo- vacuum which means that air pressure will be pressing down in all directions, and that is what makes separating them harder.
Any and all help will be appreciated. You could basically send me a few key terms to help me get my research started, or send me the name of a research paper, or suggest ways for me to get an experiment designed.
Thank you in advance! H. Kim

An energy saver light bulb of 11 W gives the same illumination as a conventional 60W light bulb. (a) If a typical light bulb is used on average for five hours a day, how much energy is saved per year by one light-bulb? (b) If each household used eight such light-bulbs, ad there are 20 million households in a country, how much energy would that country save annually?
