ATOMIC PHYSICS The nuclear atom All matter is made up of atoms which consist of a central nucleus‚ surrounded by electrons. Inside the nucleus are protons and neutrons. Particle Relative mass Charge Location Proton 1840 + Nucleus Neutron 1840 0 Nucleus Electron 1 - Outside nucleus Proton or atomic number (Z) This is the total number of protons in the nucleus of an atom. Nucleon or mass number (A) This is the total number of protons and neutrons in the nucleus of an atom. Note: a nucleon

Introduction I have chosen to investigate a factor that affects the output of a potential divider circuit. A potential divider is resistors connected in series across a voltage source; used to obtain a desired fraction of the voltage. A resistor is a device having resistance to the passage of an electric current which affects the output voltage (Vout). The factors that I could investigate are changing the resistance of r2 and record the output (Vout)‚ or use a light-dependent resistor (LDR) and change

The unknown bacteria A and bacteria B have to be identified by its genus and species. First both bacteria had to be inoculated into a TSA agar media using the streak plate method. Four quadrants were drawn‚ so that the bacteria could be isolated as much as possible. Each bacteria was inoculated into two different plates‚ so that one could be incubated at 37 degrees Celsius and the other at 25 degrees Celsius. Bacteria B‚ which was incubated at room temperature showed red colonies throughout its media

Physics 4052 Spring 2004 Y. Kubota K. Wick Project Proposal for Physics 4052 Introduction You must begin to think about a possible experimental project to carry out next semester (Physics 4052). The reason for this is two-fold: first‚ it will introduce you to the process of proposal writing‚ which is an unavoidable and very important part of modern experimentation‚ and second‚ it will enable us to make any necessary plans for procuring equipment. To start you thinking about this process‚

Since one is issued a vial of an unknown substance‚ the “purpose” as such is not exactly in doubt. The object is simply to state that obvious purpose‚ as well as summarize (a comma-ed list here is fine) the various means‚ tests‚ so forth that are performed in the approximate order that they are performed.
