1. 1. JABATAN PELAJARAN TERENGGANU BIMBINGAN EMaS TAHUN 2007 PHYSICS Module 1 Panels: Ahmad bin Ismail Noormi bin Ramli Mohd Zamry bin Abdullah Mamat bin Sulong Zainal bin Yono
2. 2. 1. Complete Table 1 by filling the appropriate column. Prefix Symbol Value nano n 10 -9 μ 10 -6 milli 10 -3 deci d k giga 10 9 TABLE 12. 50 pieces of plumbum pebles of mass 0.5 g each with diameter 0.2 mm are dropped from a height of 28 m. The pebles fall with an acceleration of 10 m s -2 before hitting a block of thin plumbum of weight 30 N. When the pebles hit the plumbum block, the tempreture increased by 1.2 oC and produced 320 J of heat energy. Based on the above description, gather the physical quantities involved according to their characteristis.3. Figure 3.1 shows a milliammeter before it is connected to a circuit. mA mirror strip FIGURE 3.1 2
3. 3. (a) (i) Name an error shown by the miliammeter in Figure 3.1. ……………………………..………………………………………................………….. (ii) What is the sensitivity of the milliammeter? .......……………….........………………………………………………………................ (b) An electric current of 23 mA is passing through the milliammeter. (i) Write 23 mA in standard form. ………………..……………………………………………………………………………. (ii) On the Figure 3.2, draw the position of the pointer if the error is not corrected. mirror strip mA FIGURE 3.2 (iii) Explain how the mirror strip can increase the accuracy of the meter reading? ................................................................................................................................. .................................................................................................................................4. Figure 4.1 and Figure 4.2 show a measuring instrument. (a) Name (i) the instrument. …………………………………………………………………………….. (ii) the physical quantity measured by the instrument. ….……………………………………………………………………………………………. 3
4. 4. X papers Zero error FIGURE 4.1 FIGURE 4.2(b) (i) State the function of part X. ………................................................................................................................ ……… (ii) What is the value of the zero error of the instrument? ………............................................................................................................................(c) Figure 4.2 shows the instrument being used to measure 25 pieces of papers. (i) What is the actual reading of the instrument? ………............................................................................................................................ (ii) Calculate the thickness of a piece of the paper. 4

Velocity / cm s-1 60 50 40 30 20 10 Time / s 1 2 3 4 5 6 7 8 FIGURE 5 (a) (i) What is the initial velocity of the ball? . …………………………………………………………………………………………………….. (ii) State the characteristic of the motion of the ball. …………………….………………………………………………………………………………… (b) Calculate the acceleration of the ball. (c) Explain how the motion of the ball obtained. …………………………………………………………………………………………………………….6. A student measured the diameter of a wire using a metre rule as shown in Figure 6.1. 20 Complete curls FIGURE 6.1 5
6. 6. (a) Why is the measurement does not start from zero? …………………………………………………………………………………………..………………… (b) State a reason why the measurement is done by 20 turns and not one turn. ………………………………………………………………………………….………………………… (c) What is the diameter of the wire? …………………………………………………………………………………………………………… (d) Suggest a suitable instrument which can be used to measure the diameter of the wire . ……………………………………………………………………………………………………………7 A student carry out an experiment to investigate the relationship between the extension of a rubber strip, y and the load, m. The apparatus arranggement is shown as FIGURE 7.1.  the is length of the rubber strip when a load is hung on it. FIGURE 7.1 Initially there is no load hung to the rubber strip. The length of the rubber strip is  . The original 0 length  is shown as in Figure 7.2. 0 The experiment is repeated using load, m = 0.3 kg, 0.6 kg, 0.9 kg, 1.2 kg and 1.5 kg. The length of the rubber strip when different load is hung to it is shown in Figure 6.2. 6
7. 7. m = 0 kg m = 0.3 kg m = 0.6 kg m = 0.9 kg m = 1.2 kg m = 1.5 kg FIGURE 7.2(a) Based on the explaination above, state the (i) manipulated variable …………………………………….……………………………………………………………… 7
8. 8. (ii) responding variable. ………………………………………………………………………………………….………… (iii) fixed variable. ………………………………………………………………………………………..…………(b) Based on Figure 7.2, determine the length of the rubber strip  and  0 when different load is used. In each measurement, calculate the extension, y of the rubber strip. Tabulate your result for m, and, y.(c) On the graph paper provided, plot a graph of y against m.(d) Using your graph, state the relationship between y and m. .....................………………………………………………………………………………………. 8
