The data set is 90 s, 91 s, 95 s and 92 s. If the minimum division in the measuring clock is 1 s, then the reported mean time should be : (1) 92±2 s (2) 92±5.0 s (3) 92±1.8 s (4) 92±3 s A person trying to lose weight by burning fat lifts a mass of 10 kg upto a height of 1 m 1000 times. Assume that the potential energy lost each time he lowers the mass is dissipated. How much fat will he use up considering the work done only when the weight is lifted up ? Fat supplies 3.8×107 J of energy per kg which is converted to mechanical energy with a 20% efficiency rate. Take g=9.8 ms−2 : (1) 2.45×10−3 kg (2) 6.45×10−3kg (3) 9.89×10−3 kg (4) 12.89×10−3 kg The temperature dependence of resistances of Cu and undoped Si in the temperature range 300-400 K, is best described by : (1) Linear increase for Cu, linear increase for Si. (2) Linear increase for Cu, exponential increase for Si. (3) Linear increase for Cu, exponential decrease for Si. (4) Linear decrease for Cu, linear decrease for Si. An arc lamp requires a direct current of 10 A at 80 V to function. If it is connected to a 220 V (rms), 50 Hz AC supply, the series inductor needed for it to work is close to : (1) 80 H (2) 0.08 H (3) 0.044 H (4) 0.065 H Arrange the following electromagnetic radiations per quantum in the order of increasing energy : A : Blue light B : Yellow light C : X-ray D : Radiowave. (1) D, B, A, C (2) A, B, D, C (3) C, A, B, D (4) B, A, D, C   |
