In Reaction 1‚ the mass of the pre-cut copper wire was measured with watch glass on the analytical balance‚ the mass was recorded using as many significant figures as possible on Table 2. The copper wire was bended into a circle and laid flat on the bottom of the 250 mL beaker. Inside the fume hood‚ 4mL 16M of HNO3 was added into the 250mL beaker that contained the copper wire. The copper wire was completely dissolved by swirling the beaker. The observation was recorded in Table 3. For Reaction 2

Nash‚ the main character‚ until I watched the movie all the way through the second time. I found it a bit confusing the way they tried to tell the story of John Nash in graduate school at Princeton in N.J.‚ and then later when he was Professor Dr. John F. Nash‚ he developed schizophrenia while at M.I.T.‚ and in a relationship with Alicia his wife. Some of this story was real to me because my Uncle Jimmy’s girlfriend Robyn went through similar treatment at the same hospital. McLean Hospital is a

in man On August 6‚ 1945 the US dropped an atomic bomb ("Little Boy") on Hiroshima in Japan. Three days later a second atomic bomb ("Fat Man") was dropped on the city of Nagasaki. These were the only times nuclear weapons have been used in war. Reasons for the bombing Many reasons are given as to why the US administration decided to drop the atomic bomb on Hiroshima and Nagasaki. Reasons include the following: • The United States wanted to force Japan’s surrender as quickly as possible to

namely the Earth. Photovoltaic technology directly converts solar energy into electricity. Photovoltaic thin film solar cells are easy to handle ‚ inexpensive and also easy to use. Thin film panel is flexible and can tolerate a bullet hole without failing and can greatly increase the surface area and the absorption coefficient needed to generate electricity. This paper will discuss the advantages and disadvantages of the thin- film solar cell and also describe its application and how its work. Introduction:

Experiment 112-5 Thin Film Interference Introduction When two waves of equal intensity combine‚ the intensity of the resulting wave can be anywhere between zero and four times the intensity of the individual waves‚ depending upon the phase difference between them. When they are in phase (the maxima coincide with maxima and the minima coincide with minima)‚ maximum intensity results. When they are exactly out of phase (the maxima of one wave coincide with the minima of the other wave)‚ the

resistance of a wire Introduction: Resistance is a force‚ which opposes the flow of an electric current around a circuit. Resistance is measured in Ohms. George Ohm discovered that a circuit sometimes resists the flow of electricity. He called this ’RESISTANCE.’ He even came up with a rule for working out the resistance of a circuit‚ which was: R= V ÷ I V- Volts I- Current R- Resistance Ohms law says the more resistance means more energy is needed for the current to pass through the wire.
