Description

Adding more masses to the hook hanging from the string increases the speed of the progressive wave along the string.

b Explain why there are no ‘lost volts’ across the internal resistance of the battery when the reading is 6. frequency Use your displacement–distance diagram to answer parts b-d: b Mark a point that is in phase with A. Exam-style questions allow students to thoroughly prepare for examinations and check answers which are provided on the CD-ROM at the back of the book. c Calculate the increase in electrical potential energy when the +20 C charge is pushed from C to D.Momentum calculations The following exercise provides practice in rearranging and using the equation for momentum. d State the distance in centimetres between a node and the nearest antinode and compare this distance with the wavelength λ of the progressive wave.

b Outline how to use the resistivity of the core to find the thickness t of a line of width w and length l drawn by the pencil on a piece of paper. Newton’s law of gravitation Isaac Newton discovered the law that describes the gravitational pull of one object on another. A radioactive nucleus decays with the emission of an α-particle and a γ -particle Describe the changes that occur in the proton number and the nucleon number of the nucleus. Cambridge International AS and A Level Business Coursebook with CD-ROM (Cambridge International Examinations) [3 ed.Using the correct terms to explain stationary waves It is important to be able to use terms such as amplitude and phase correctly and to make comparisons. g The coherent light is replaced by light of the same wavelength, but from two different sources that are not coherent. The definition of gravitational field strength g says that its value is the force acting per unit mass acting near a body of mass m. More about phase difference This exercise focuses on phase difference and how it can be shown in wave diagrams.
