HW 1 solutions Point Charge in One Dimension A point charge q1 = -3.5 μC is located at the origin of a co-ordinate system. Another point charge q2 = 5.1 μC is located along the x-axis at a distance x2 = 9.3 cm from q1. 1) What is F12‚x‚ the value of the x-component of the force that q1 exerts on q2? -18.57 N For all of these problems we want to make use of the standard electric force equation: ̂ So for this problem with K=9*109 Nm2/C2‚ Q1=-3.5μC‚ Q2=5.1 μC‚ and r=9.3 cm we get F=-18.57

The Atom The basic idea of the atom was adopted by scientists thousands of years later because it explained new discoveries in the field of chemistry. Long after chemical atoms were found to be divisible‚ and even after smaller‚ truly indivisible particles were identified. Over time theories of the atom changed. The nature of atoms in philosophy varied a lot over time and between cultures and schools. The Plum Pudding Model was proposed in 1904 before the discovery of the atomic nucleus in order

Cebu Institute of Technology Phys 202 /K3 I. Title: Specific Heat of Solids II. Object: To determine the specific heat capacity of solids by methods of mixtures. III. Theory: When to or more substances at different temperatures are mixed‚ heat will flow from the substance of higher temperature to the substance of lower temperature. The heat flow will continue until equilibrium in temperature is reached. From the Law of Conservation of Energy‚ whatever amount of heat is lost by the hot substance

Mie resonances in dielectric particles can increase the local optical density of states (LDOS) associated with either electric or magnetic transition rates in nearby quantum emitters without ohmic losses. Their rather large quality factors compensate their low field confinement as compared to the plasmon resonances of metallic nanostructures for which nonradiative decay channels dominate. We show theoretically that near-infrared quadrupolar magnetic resonances in silicon particles can preferentially

PHYS1110 Lab report: “Why does your kettle boil”. To do this investigation‚ I agree that I will follow all the risk control methods and conduct the experiment in a very safe condition. The aim of this investigation is to find out more about boil water by using a kettle. For example‚ time taken to boil different volumes of water‚ specific heat of water and power of kettle. Equipment: This picture shows all the equipment that I used to do the experiment including a stop watch‚ a measuring

CHAPTER 5 STATES OF MATTER INTERMOLECULAR FORCES Intermolecular forces are the forces of attraction and repulsion between interacting particles (atoms and molecules). Attractive intermolecular forces are known as van der Waals forces. van der Waals forces include dispersion forces or London forces‚ dipole-dipole forces‚ and dipole-induced dipole forces. A particularly strong type of dipole-dipole interaction is hydrogen bonding. Dispersion Forces or London Forces Observed between non-polar molecules

Why will insulators affect how long a test tube of hot water stays hot? Background Information I know that there are many different ways of insulating this test tube‚ shiny foil can be used because it’s a poor emitter of radiation and it will reflect escaping heat by reflecting‚ because this method is used in flasks to keep hot drinks warm. Though it is a good conductor so will lose heat through to surfaces its touching but it shouldn’t matter because it will be touching air and glass which both
