This historic book may have numerous typos, missing text or index. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. 1900. Not illustrated. Excerpt: ... HARVARD COLLEGE ADMISSION EXAMINATIONS IN PHYSICS i8 90 -- 1900 PHYSICAL SCIENCE ALTERNATIVE H Omit any three questions. If the candidate answers more than five questions he should designate those which he wishes to have regarded as extra ones, otherwise his mark will be five times the average of the marks on the questions answered. Show the processes by which numerical answers are obtained.] 1. A certain body appears by the indications of a spring balance to weigh 15 g. in air and 10 g. in water. (a) If the balance is correct, what is the specific gravity of the body? (b) If each reading of the balance is only T DEGREES as large as it should be, what is the specific gravity of the body? 2. If the weight of a c.c. of air is .0012 g. at atmospheric pressure, how many times the ordinary atmospheric pressure would be required to compress air to the density of water, provided the law of compression should hold which your experiments have taught you? 3. Three forces, all applied to the same point, are in equilibrium with each other. If one of these is a force pulling north and another is a force pulling east, show how to find by means of a diagram the direction and magnitude of the third force. Mark the direction of each of the three forces. in your figure by means of an arrowhead. 4. A uniform bar 6 ft. long and weighing 8 lbs. is loaded at one end with an 8-lb. weight. (a) At what distance from this end must a supporting point be placed in order that the whole may balance with the bar in a horizontal position? (b) If the bar is hinged at the unloaded end, how much work must be done in order to raise the loaded end 2 ft.' 5. Describe, with a drawing, the apparatus which you have used in measuring the expansion of a metal bar. 6. Describe any experiment in sound upon w
