Some nuclei magnetic are caused when the charge and spin are possessed and give various properties on the proton under investigation in which their behavior in an external magnetic field is influenced. Properties include the magnetic moment of the rotating nucleus will precess around the magnetic field direction under the influence of external magnetic field. The frequency of precession of a proton under investigation is directly proportional to the magnetic field strength. The frequency and precessional frequency of the proton under investigation must be matched with each other after irradiated with the radio frequency (electromagnetic) radiation in order to investigate the resonance. The proton is raised to the higher energy spin state after absorbing the electromagnetic energy.

Physics 1408 Section E1 Standing Waves in a Vibrating Wire Callie K Partner: Miguel E Date Performed: March 20, 2012 TA: Raziyeh Y Abstract This lab had two purposes. The first was to determine the relationship between the length of a stretched wire and the frequencies at which resonance occurs. The second was to study the relationship between the frequency of vibration and the tension and linear mass density of the wire. In the first part we found the resonance, frequency and wavelength of a wire and used this data to calculate the speed of the traveling waves. For first harmonic, our wavelength was 1.200 m, found by the formula λ=2L/n.

Technically, electricity is created by particles that carry a charge, usually electrons. In a wire or any other conductor, electrons move freely around the stationary atomic nuclei making up the conductor. Electrical current is the movement of these charged particles. In most conductors, the flow of electrons is impeded by some resistance, which can be thought of as collisions of electrons with the nuclei or other electrons. This creates an atomic-level "friction" which produces heat (and light in some cases, such as a light bulb or glowing heater element).
• The electron, the proton and the neutron are the "building blocks" of the atom. Protons have a positive electrical charge (p+), and neutrons which have about the same mass, are electrically neutral, or have no electrical charged (n0). Electrons, which are much less massive than protons - only about 1/1836th as heavy - have a negative electrical charge (e-). All atoms are made of protons, neutrons and electrons, though most hydrogen (1H1) has just the proton in its nucleus and a lone electron in orbit. 3.
DEPARTMENT OF PHYSICS LAB REPORT FOR Title of Experiment: Newton’s Second Law Experimenters: Authors of this Report: Experiment Performed on: Monday, January 28th, 2013 Report Submitted on: Monday, February 4th, 2013 Teacher’s Assistant Name: Objective and Background Newton was the first one to identify the connection between motion and force. Newton’s second law of motion states that acceleration is dependent on two variables; the net force (F1 + F2 + F3 + F4 +...) and mass. This law states that the acceleration acting on an object is directly proportional to the net force and is inversely proportional to the mass of an object. For example; heavier objects require more force to move the same distance as lighter objects. Newton’s second law of motion is expressed as a mathematical equation: Fnet = ma (Force = mass*acceleration) A significant notion of this equation is that an object accelerates in the direction of the new force, and acceleration is created by the net force.
