Consider two future observatories in space. Observatory X consists of a single 50-meter telescope. Observatory Y is an interferometer consisting of five 10-meter telescopes, spread out over a region 100 meters across. Which observatory can detect dimmer stars, and which one can see more detail in its images? (Assume all else is equal, such as quality of optics, types of instruments, and so on.)
a. Observatory X can detect dimmer stars and Observatory Y reveals more detail in images.
b. Observatory Y both detects dimmer stars and reveals more detail in images.
c. Both observatories have the same capabilities, but Observatory Y would be cheaper to build.
d. Observatory X both detects dimmer stars and reveals more detail in images.
e. Observatory Y can detect dimmer stars and Observatory X reveals more detail in images.

Aleaky 10-kg bucket is lifted from the ground to a height of 15 m at a constant speed with a rope that weighs 0.7 kg/m. initially the bucket contains 45 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 15-m level. find the work done. (use 9.8 m/s2 for g.) show how to approximate the required work by a riemann sum. (let x be the height in meters above the ground. enter xi* as xi.) lim n β β n (9.8)(45β3 xi) i = 1 Ξ΄x express the work as an integral. 0 dx evaluate the integral.
