The next generation of ground based telescopes will have pri- mary mirrors tens of meters wide. the thirty meter telescope (tmt), with a primary site choice of manua kea, is an example of such a telescope. (a) how much more light will tmt collect compared to the keck 10-m tele- scope currently in operation? (b) the tmt will have a naysmyth focus with a total focal length of 450-m. what is its plate scale (in arcseconds/mm)? (c) imagine that a particular instrument employs a 2048 x 2048 ccd detector that is 2.66 cm across (this is similar to a camera called megacam on the cfht). what is the field of view of the camera in arcseconds? can it fit jupiter? what about neptune? (feel free to looks these up! ) (d) your professor studies weather patterns on unresolved brown dwarfs (r~rjupiter) by obtaining light curves that measure how a brown dwarf's brightness changes as it rotates and cloud features come in and out of view. will tmt finally be able to resolve surface features on the nearest brown dwarf (at a distance of -6.5ly)?

Consider motion in one dimension. (the sign of the vector quantities is their direction indicator.) an object moves in the positive x-direction with speed 2.9 m/s for 4.5 s. it stops for 3.8 s and then moves in the negative x direction with speed 2.8 m/s for 4 s. what is the total distance traveled by the object in units of meter? enter a number with two digits behind the decimal point.

Lake happy times contains 100 km3 of pure water. it is fed by a river at a rate of 50 km3/yr. at time zero, there is a factory on one shore of lake happy times that begins introducing a pollutant to the lake at a rate of 2km3/yr. there is another river that is fed by lake happy times at a rate that keeps the volume of lake happy times constant. this means that the rate of flow from lake happy times into the outlet river is 52km3/yr. in turn, the flow from this outlet river goes into another lake, lake sad times, at an equal rate. finally, there is an outlet river from lake sad times flowing at a rate that keeps the volume of lake sad times at a constant 100 km3 . (a) find the amount of pollutant in lake sad times at the end of 3 months. (b) at the end of 3 months, observers close the factory due to environmental concerns and no further pollu- tant enters lake happy times. how long will it take for the pollutant in lake sad times (found in part (a)) to be cut in half?
