d., time State the quantity from the list that is conserved in: a Kirchhoff ’s first law b Kirchhoff ’s second law.

State whether the pressure of the air would be greater or less than the value you have calculated in part g. Answers to all exercises and exam-style questions are provided on the CD-ROM for students to use to monitor their own understanding and track their progress through the course. 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. d Draw the shape of another stationary wave that forms on the same length of string but which has a larger wavelength than shown in the diagram. By using the Web site, you confirm that you have read, understood, and agreed to be bound by the Terms and Conditions.

An atom of 238 U decays progressively into 206 82Pb by emitting eight α-particles and a number 92 − of β -particles. It is usually best to work in seconds and convert to minutes or hours as the last step in a calculation. This diagram shows the path of a projectile – in this case, an arrow – fired at 45° to the horizontal with an initial velocity of 24 m s −1. Gravitational potential energy and kinetic energy You can calculate the GPE and the KE of an object using these equations: Ep = mgh Ek = 21 mv2 In this exercise you will look at the derivations of these equations.

c In an attempt to determine g using projectile motion, a student fires a metal ball with an initial velocity of 12. Remember: a compression is where the coils are close together; it is half a wavelength from the nearest rarefaction, where the coils are far apart. This exercise helps you think about the relationship between resistance, length and area, and the difference between resistance and resistivity. a Draw a similar diagram to represent the electric field around a metal sphere with a negative electric charge. Calculating force and field strength We define electric field strength at a point in a field in terms of the force on a positive charge placed at that point.d State the number of times per second that the modulated wave goes from maximum to minimum amplitude.
