The radius of curvature of a curved mirror is defined as the radius of the hollow glass sphere of which the spherical mirror was (previously) a part. Note that any line drawn from the center of curvature C to the mirror surface meets it at right angle and equals the radius of curvature. Principal Axis :The principal axis of a curved mirror is defined as the imaginary line passing through its pole P and center of curvature C. Focus :The principal focus is defined as the point on the principal

8.2 The World Communicates Contextual Outline Humans are social animals and have successfully communicated through the spoken word‚ and then‚ as the use of written codes developed‚ through increasingly sophisticated graphic symbols. The use of a hard copy medium to transfer information in coded form meant that communication was able to cross greater distances with improved accuracy of information transfer. A messenger was required to carry the information in hard copy form and this carrier could

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

COST-VOLUME PROFIT (CVP) ANALYSIS This is a technique used for planning short-term run profits by finding the relationship between profits and factors that influence profits. The following factors are taken to be influencing profits:- • Selling price • Variable cost of production • Fixed costs • Activity level (production and sales units) Profit planning is based on break-even analysis and can be worked out using either; a) Algebraic method b) Contribution method c) Break-even

being used in this particular experiment is symmetrical and is taking place in a wind tunnel with a speed of 18.5m/s‚ therefore the flow is assumed to be incompressible. The different pressures along the surface of the aerofoil will be measured at an angle of attack of 4.1 degrees and 6.2 degrees. These values of pressure will then be analysed and graphs and calculations will be produced‚ the lift being calculated using the trapezium method in excel and these values and graphs will then be compared to
