Figure 4 4 b i On Figure 4, mark and label the forces that act on the ball when in this position. The cylinder wouldbe released from rest as it opened S1. The ball carries a chargeof —0.
Calculate themagnitude of the electric field strength between the plates, assuming it is uniform. In one of his results, the initial pdwas BThursday 27 January 20 11 1.
Figure 1 shows how the force between the boot and the ball varieswith time while they are in contact. The distance between the plungers was 2. Show that the maximum force on the wire is about 40 mNwhen there is an alternating current of rms value 2. It travels around the Earth once every 97 minutes.
Calculate the magnitude of thecentripetal force that acts on it. Explain how he should use the measurementstaken to calculate the acceleration of the cylinder down the slope.
Explain whythe wire will vibrate vertically. Once opened, the switches would remain open.
The principle ofthis arrangement is shown in Figure 2. The quality of your written communication will be assessed in this question. Figure 1 2 b i What is the significance of the area enclosed by the line on a force —time graph and thetime axis when a force acts on a body for a short time?
Express your answer toan appropriate number of significant figures. Do not write outside the box 11 5 c The length of PQ is 0. Wiresconnected to a circuit at P and Q allow an electric current to be passed through the wire.
Figure 2 S1and S2are two switches that would be opened in turn by plungers as the cylinderpassed over them. Answers writtenin margins or on blank pages will not be marked. He suggested anarrangement that would make use of a capacitor-resistor discharge circuit to measure thetime taken for the cylinder to travel between two points on the slope.
For this paper you must have: Ashort section of the wire is positioned between the pole pieces of a permanent magnet,which applies a uniform horizontal magnetic field at right angles to the wire. Figure 5 5 a i State the direction of the force on the wire when there is a direct current fromP to Q, as shown in Figure 5.
The pd across the capacitator would be measuredby the voltmeter. Figure 3 4 a i A pd of V is applied between P1and P2when the switch is closed.Aqa-Scly1-W-Qp-Jun11 Essay General Certificate of Education Advanced Subsidiary Examination June Sociology Unit 1 Wednesday 18 May For this paper you must have: an AQA 8-page answer book.
