Suppose now that the ice is tranparent enough so that some sunlight makes it rhough. Let's see how that would change the ice thickness. a) calculate the globally averageed solar flux incident on Earth's surface during the Neoproterozoic glaciation (0.6 Ga) S=1302.066 W/m^2 b)the solar flux at the equator is about 20% higher than the global average value. suppose that 10% of this incident sunlight makes it through the ice. How thin must the ice layer be in order to conduct this heat back out so that the water temperature remains constant? F=lambda x change in temperature/change in thickness of the ice layer. F is the geothermal heat flux. Current geothermal heat flux is about 0.09 W/m^2 c) is the ice thickness calculated in part b consistent with the assumption that it would transmit 10% of the sunlight through it?

Let's look at a super conductor: so resistivity really is zero exactly, and some of our electrostatics assumptions about E=0 in a conductor and the charge is all on the surface really are true a) Show the magnetic field must be constant inside b) If you built a loop out of superconducting material, show that the magnetic flux through that loop must be constant c) Turns out B is not only constant in a super conductor, but zero. Why? Eddy...

Southern Star Cold Storage (SSCS) produces ice machines. Some of the ice machines SSCS makes require a component called a type AF condenser. Accordingly, SSCS produces 20,000 type AF condensers each year. Halifax Electric has offered to supply SSCS with the condensers for $101 each. The facilities SSCS uses to make the condensers can be rented to another company for $24,000 per year. SSCS’s annual production cost for the type AF condensers is as follows: Direct material $ 940,000 Direct...

Is it worth going to college? Let's suppose that a typical college educated professional makes 85,000 dollars per year and a high school graduate makes 45,000 dollars per year. The direct costs of college (tuition, books, and so on) are 16,000 dollars a year (and a college degree takes 4 years). For the purpose of this exercise, consider that the earnings are constant until the age of 64; and thereafter, the earnings are zero. (a) Suppose that John is now...

In some states, the use of marijuana is now legal, so a majority of the citizens evidently regard it as morally acceptable. In other states, however, the use of marijuana is illegal, so a majority of the citizens in those states evidently regard it as morally unacceptable. Furthermore, given that most states at this time disapprove marijuana use, a majority of citizens in the country as a whole likely regard it as morally unacceptable. The dilemma for those who say...
