Purpose : To learn how to use vernier caliper‚ micrometer and spherometer to measure internal and external diameters of a pipe‚the thickness of a copper rods‚ and the radius of curvature of spherical lenses. 1) Vernier caliper: As shown in Fig. 1 the main fixed scale in the vernier caliper has 1 mm gradations while th sliding scale (vernier scale) has 0.05 mm gradations. The smallest division of vernier scale is called the least count of vernier caliper. It may be different for different vernier calipers

Make a pendulum clock whose pendulum has a period of two seconds. Calculations shows that the length of a pendulum if this period with a fixed support would be about one meter. Make a pendulum with a yielding support. ix) Use the results from the experiment to calculate a value for d that would give a period of two seconds for the pendulum used. x) Use your answer to (ix) to suggest whether the use of a yielding support would save space.

spin‚ she will put her arms out away from her body to create a slow spin. As she tucks her arms in‚ she will spin much more rapidly. By moving her mass closer to the axis‚ she reduced her moment of inertia. Many practical applications for this experiment exist. Car manufacturers study it carefully to determine how quickly a car will spin out of control. Here‚ a higher moment is created such that the car is less likely to lose control in a spin. Many sports also use the concept‚ as in the example

Independent Assessment Physics Lab (SL): Cantilever Flexion Cherno Okafor Mr. Ebrahimi SPH4U7 October 21st‚ 2012 Introduction Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence‚ the objective is to establish a relationship between the length of a cantilever‚ which may give some insight into the physics of cantilevers. Hypothesis: If one increases the length of a cantilever‚ one would expect there to be an

Height of Ball Drop v/s The Depth of the Crater | By Tejas Shah‚ IBDP Year 1 | | | | | | | * Aim- To find the relationship between the depth of crater and the height from which it is dropped. * Research Question- Does the height from where the ball is released affect the depth of the crater. * Hypothesis- If we increase the height of the drop of the ball; the depth of the crater would increase. This is because as there is loss in potential energy subsequently there

specific heat of solids 1. Introduction Heat capacity of a body is the quantity of heat required to raise the temperature of the body by 1oC. The specific heat of a substance is the heat capacity per unit mass. Thus‚ heat capacity = mass x specific heat. The specific heat is essentially a measure of how thermally insensitive a substance is to the addition of energy. Heat and temperature are really different quantities. Heat is a quantity of thermal energy‚ while temperature determines the

Experiment 10 – Enzymes Enzymes are proteins that act as catalysts for biological reactions. Enzymes‚ like all catalysts‚ speed up reactions without being used up themselves. They do this by lowering the activation energy of a reaction. All biochemical reactions are catalyzed by enzymes. Since enzymes are proteins‚ they can be denatured in a variety of ways‚ so they are most active under mild conditions. Most enzymes have optimum activity at a neutral pH and at body temperature. Enzymes are
