1) sections 1, 2, and 10 are significant primarily because they suggest the likelihood that a) widow wycherly is actually the woman in the full-length portrait. b) dr. heidegger wants to include his guests in an experiment with the water. c) dr. heidegger plans to drink some of the water from the vase and needs witnesses. d) the guests will be asked to witness dr. heidegger's transformation when he drinks the water.

Comedians like to joke that the reason we havenΓ’β¬β’t been visited by intelligent life from elsewhere in the universe is that aliens have been monitoring earthΓ’β¬β’s broadcasts of intellectually embarrassing tv programs, like gilliganΓ’β¬β’s island, fear factor, the jersey shore, and the jerry springer showand so consider us far too primitive to merit a visit. letΓ’β¬β’s check the assertion that aliens could have been receiving them. tv programs are broadcast at a frequency of about 100mhz with about 100kw of total power in 30frames per second, which emanatesroughly uniformly in all directions. assume that interstellar space transmits these broadcasts without attenuation. no matter how smart they are, aliens would require at least one photon per frame to interpret our signals. findthe number of photons per unit time per unit area reaching a receiver on a possible planet in the nearest star system, which is about 4 light-years away (a light-year is the distance light travels in a year). if aliens aimed a receiver or detector directly at earth, how big (in diameter) would it have to be to receive a photon per frame

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^β2m on an edge at the ocean's surface, decrease by 7.5 x 10β10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^β2, delta v=7.5x10^β10. at some point l needs to be cubed. why p is divided by delta v?
