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

Objective: To study the conservation of energy and momentum using projectile motion. Theory: The ballistic pendulum demonstrates both the constant horizontal velocity in projectile motion and the conservation of momentum. Because there is no acceleration in the horizontal direction‚ the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system‚ if no net external force acts on a system of particles‚ the total

Prediction I think that the speed of the cart will decrease as more weight is added on top of the cart. This is because the more weight that is placed on the moving vehicle/object‚ the more downward force is produced. This would increase the friction between the wheels of the cart and the ramp’s surface. The increase in friction would slow down the moving object (cart). Apparatus Trolley/cart- this is essentially a wooden block with wheels and a rubber end‚ to provide the collision with a

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
