Question 2.1: (i) Calculate the number of electrons which will together weigh one gram. (ii) Calculate the mass and charge of one mole of electrons. * ------------------------------------------------- Answer (i) Mass of one electron = 9.10939 × 10–31 kg Number of electrons that weigh 9.10939 × 10–31 kg = 1 Number of electrons that will weigh 1 g = (1 × 10–3 kg) = 0.1098 × 10–3 + 31 = 0.1098 × 1028 = 1.098 × 1027 (ii) Mass of one electron = 9.10939 × 10–31 kg Mass of one mole of

a muscle is determined by the major type of motor unit being recruited‚ as well as the rate in which action potentials are being fired. A subject performed two tests‚ one to display the correlation between tension and electrical activity in the muscle‚ in which a sequence of four increasing-strength grips were performed‚ and the second test studied the effects of fatigue in which a continuous

CHAPTER 4 Objectives: 1. Define consciousness.--------- 2. Appreciate the role of the circadian rhythm. 3. Describe the stages (5) of sleep including the sequence of the stages. The development of the electroencephalograph led to dramatic increases in what is known about sleep. When electrodes are attached to the face and scalp of sleepers‚ different patterns are produced on the graphic record called the electroencephalogram or EEG. The patterns vary in frequency and amplitude of the waves

❶ A quality control engineer is in charge of testing whether or not 95% of the Blu-ray disc players produced by his company conform to specifications. To do this‚ the engineer randomly selects a batch of 13 Blu-ray players from each day’s production. The day’s production is acceptable provided no more than 1 Blu-ray player fails to meet specifications. Otherwise‚ the entire day’s production has to be tested. (a) What is the probability that the engineer incorrectly passes a day’s production
