** Atom and Introduction to Nuclear physics ** Introduction Alpha-particle scattering 2.1 Experimental set-up ➢ Alpha particle o is a high-energy helium nucleus with 2 protons and 2 neutrons. o has 2 positive charges. ➢ Gold foil was chosen since it has a high atomic mass. Thin gold foil‚ ~10-6m was bombarded by high-energy alpha particles. ➢ Angular deflections/ scattering of alpha particles were measured by observing

PHYSICS II ELECTRICITY‚ MAGNETISM‚ SOUND‚ AND LIGHT SERIES CIRCUIT In this unit you’ll begin learning how to analyze circuits. Circuit analysis means looking at a schematic diagram for a circuit and computing the voltage‚ current‚ or power for any component in that circuit. Closely related to the task of circuit analysis is the task of troubleshooting‚ which means figuring out what is wrong in a circuit that is not working correctly. Analyzing and troubleshooting go hand in hand; when a circuit

Experiment 9: THE TANGENT GALVANOMETER; PURPOSE: In this experiment we will measure the magnitude of the horizontal component of the Earth’s Magnetic field by the use of an instrument called a tangent galvanometer. INTRODUCTION: A tangent galvanometer consists of a number of turns of copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of

Motion NCERT Chapter Questions and Answers and other Q & A Q1: An object has moved through a distance. Can it have zero displacement? If yes‚ support your answer with an example. Answer: Yes an object can have zero displacement even though it has moved through a distance. It happens when the object moves back to its original position i.e. final position coincides with the starting position. Example: Suppose an object travels from O to C and then comes back to original position O. Total

Intent: The goal was to investigate the time taken for the pendulum to oscillate for a time period. Results: Table of Content Objectives i) Tie the end of a thread to a hole in the end of a metal plate so that the length l of the pendulum is about 0.5m. Record the value of l. ii) Clamp the metal plate to the frame so that the plate protrudes horizontally from the frame. The length d from the edge of the frame to the thread should be 0.24m. iii) Measure and record the value of d. iv) Determine
