1. Motion in a Circle 1.1. Radians Radian: one radian is the angle subtended at the center of the circle by an arc of length equal to the radius of the circle Angular displacement: the angle through which an object moves through a circle Hence 1 revolution is 0.1sec Use angular velocity formula 2π ω = 0.1 = 62.8 Using relation between angular and linear velocity v = ωr = 62.8 × 0.2 = 12.6 ms-1 1.3. Circular Motion s = rθ

Absolute Zero - correct answer-The theoretical temperature at which the molecules of a substance have the lowest energy and hence the substance has minimum internal energy and no kinetic energy acoustic impedance - correct answer-product of density of medium and speed of sound in medium Activity - correct answer-The number of atoms of a radioactive substance that decay per unit time. amplitude modulation - correct answer-amplitude of carrier wave varies in synchrony with the displacement...

Physics 9702 A2 Level Definitions

State what may be deduced from the difference in the temperature of two objects. - The direction or rate of transfer of (thermal) energy. State what is meant by thermal equilibrium of two bodies. - Temperature of two objects is the same. Therefore there is no net transfer of energy between the two objects. State the basic principle by which temperature is measured. - It uses a property (of a substance) that changes with temperature. Explain why two different calibrated thermometers may rec...
