Express each approximation of 蟺 to six significant figures: (a) 22/7 and (b) 355/113. (c) Are these approximations accurate to that precision?
(a)The six significant figures of 22/7 is 3.14285
(b)The six significant figures of 22/7 is 3.14159.
(c) The approximation 355/113 is more accurate than 22/7.

How many nanoseconds does it take light to travel 1.00 ft in vacuum? (This result is a useful quantity to remember.)?
Question: The purity of gold can be tested by weighing it in air and in water. How? Do you think you could get away with making a fake gold brick by gold-plating some cheaper material?
Question- Neptunium. In the fall of 2002, scientists at Los Alamos National Laboratory determined that the critical mass of neptunium-237 is about 60 kg. The critical mass of a fissionable material is the minimum amount that must be brought together to start a nuclear chain reaction. Neptunium-237 has a density of 19.5 g/cm3. What would be the radius of a sphere of this material that has a critical mass?
Consider a spacecraft in an elliptical orbit around the earth. At the low point, or perigee, of its orbit, it is 400 km above the earth鈥檚 surface; at the high point, or apogee, it is 4000 km above the earth鈥檚 surface. (a) What is the period of the spacecraft鈥檚 orbit? (b) Using conservation of angular momentum, find the ratio of the spacecraft鈥檚 speed at perigee to its speed at apogee. (c) Using conservation of energy, find the speed at perigee and the speed at apogee. (d) It is necessary to have the spacecraft escape from the earth completely. If the spacecraft鈥檚 rockets are fired at perigee, by how much would the speed have to be increased to achieve this? What if the rockets were fired at apogee? Which point in the orbit is more efficient to use?.
Water flows steadily from an open tank as in Fig. P12.81. The elevation of point 1 is 10.0 m, and the elevation of points 2 and 3 is 2.00 m. The cross-sectional area at point 2 is 0.0480 m2; at point 3 it is 0.0160 m2. The area of the tank is very large compared with the cross-sectional area of the pipe. Assuming that Bernoulli鈥檚 equation applies, compute (a) the discharge rate in cubic meters per second and (b) the gauge pressure at point 2.
