Soalan 1 Question 1 Ali ingin mengukur suhu badannya menggunakan suatu transduser. Beliau mendapat bacaan rintangan seperti yang disenaraikan dalam Jadual 1. Beliau mengandaikan transduser tersebut bertindak secara linear dalam ketiga-tiga keadaan seperti yang digambarkan dalam Jadual 1. Ali wants to measure his temperature using a transducer. He obtained the resistance readings as listed in Table 1. He assumed that the transducer acting linearly in the three conditions as tabulated in Table 1. Keadaan/Condition Air berais Ice water (E) Mulut Ali Ali's mouth (EA) Air Mendidih Boiling water (E) Jadual 1/ Table 1 Rintangan/Resistance (k(2) 71.7 9.3 1.0 (a) Senaraikan transduser yang mungkin boleh digunakan oleh Ali untuk mendapatkan bacaan seperti dalam Jadual 1. Berikan justifikasi jawapan anda State the possible transducer that Ali could use to attain the reading as in Table 1. Justify your answer. (3 markah/marks) (b) Dengan mengandaikan suhu sekeliling, To= 293 K, tentukan nilai yang terhasil untuk suhu di mulut Ali. Assuming that the ambient temperature T = 293K, determine the resulting value for the temperature in Ali's mouth. (7 markah/marks) (c) Jika keadaan di atas ditukar di mana suhu berubah dari 300 K ke 320 K, ramalkan perubahan-perubahan kepada nilai rintangan. Plotkan graf untuk menyokong jawapan anda. If the above condition is changed where the temperature is varied from 300 K to 320 K predict the changes in the resistance value. Plot a graph to support your answer. (5 markah/marks)
