Description

in terms of the energy transferred by a source in driving unit charge around a complete circuit distinguish between e. d The signal wave causes the frequency of the modulated wave to change from the maximum to the minimum and then back to the maximum frequency 20 times a second. Outline how you could use the absorption properties of nuclear radiation to show that a radioactive source emits only γ-radiation. Exam-style questions TIP Be careful not to confuse questions on the double-slit experiment and on the diffraction grating.

Diffraction and the diffraction grating This exercise helps you understand the role of diffraction and gives you practice in using the diffraction grating formula.These graphs show how the voltage across a capacitor and a rechargeable battery change with time when they are connected across a resistor. b Copy the sketch graph and add a second line to the graph representing the motion of a car moving with a higher constant velocity. The idea of resolving a force to find its component in a particular direction can be extended to any other vector quantity.

Add an arrow to your diagram to show the approximate direction of the resultant force on the particle. Density calculations are not complicated but, in these examples, you will have to calculate the volume of a sphere and work with numbers in standard form (scientific notation). radio waves ultrasound waves microwaves ultra-violet waves waves on a rope c Describe how to use a long spring to produce a longitudinal wave that travels along the spring. Exam-style questions are also accompanied by estimated timings to help students to manage their time effectively in the exams.

Force and momentum When a force acts on a body and there is a displacement, work is done by the force on the body. Sketch the graph you would expect to obtain and indicate how you would deduce the Young modulus from the graph. b Determine the number of amplifiers necessary along the cable for the final signal to be of the same power as the initial signal. d Explain how Kirchhoff ’s second law can be applied to the closed loop that contains just the three resistors. b The current direction is changed so that current enters the top face of the film and leaves by the lower face.

d Check that you get the same answer to c using the equation: TIP Because the four suvat equations are connected to each other, you can usually find a way of using an alternative equation to check an answer. frequency Use your displacement–distance diagram to answer parts b-d: b Mark a point that is in phase with A. a Explain how you can tell from the pattern of the field lines that this is a uniform electric field.A student used a stopwatch to measure the time taken by a trolley to travel a measured distance of 1.
