Q4/ A- The light bulb is made from tungsten metal (d 19.3 g/cm3) that has been drawn into a very thin wire. The diameter of the wire is difficult to measure directly, so it is sometimes estimated by measuring the mass of a fixed length of wire. If a 0.200 m length of tungsten wire weighs 5 mg, then what is the diameter of the wire? Express your answer in millimeters. B- The total volume of ice in the Antarctic is about 3.01x10° km. If all the ice in the Antarctic were to melt completely, estimate the rise, h, in sea level that would result from the additional liquid water entering the oceans. The densities of ice and fresh water are 0.92 g/cm3 and 1.0 g/cm3, respectively. Assume that the oceans of the world cover an area, A, of about 3.62 x10° km? and that the increase in volume of the oceans can be calculated as A xh?

As a first approximation. Earth's continents may be thought of as granitr blocks floating in a denser rock (called peridotitc) in the same way that ice floats in water. (a) Show that a formula describing this phenomenon is gt = pd where g is the density of granite (2.8 103 kg/m3), p is the density of peridotite (3.3 103 kg/m3), t is the thickness of a continent, and d is the depth to which a continent floats in the peridotite. (b) If a continent sinks 5.0 km into the peridotite layer (this surface may be thought of as the ocean floor), what is the thickness of the continent?
You are part of a team in an engineering class that is working on a scale model of a new design for a life vest. You have been asked to find the mass of a piece of foam that will be used for flotation. Because the piece is too bulky to fit on your balance, you break it into two parts. You measure the mass of the first part as 128.3 0.3 g and the second part as 77.0 0.3 g. a. What are the maximum and minimum values for the total mass you might reasonably report? b. What is the best estimate for the total mass of the foam? Hint: Propagation of uncertainty is described in Appendix A.
