Use these measurements to complete the entry for tin in the Periodic Table that would be used on 98765 ALEKS. Be sure your answers have the correct number
of significant digits.
Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for tin in the Periodic Table we use here on Earth.

- At a neutrino detection facility deep underground in an abandoned salt mine, a research team is making calculationson how muchof two materials they will need in order to line the inside of adetection tank. The detection tank is a large sphere with an interior radius of 45.55 ft±0.500in. The two materials needed are gold with a density of 19.33 g/cm3and titanium with a density of 0.1630 lbs/in3. On the interior, the titanium layer will be applied first and the gold on top of that. The researchers look to purchaseenough titaniumto apply a layer that covers the entire interior of the sphere and has a thickness of 1.335 cm±0.500cm. Theprice of titaniumis $29.00per kg. On top of the titanium, the researches need to apply a layer of gold that is 700.0 microns thick and coversthe entire interior of the tank. The price of gold is $2,035per oz.

Other nuclear reactions in the Sun supplement this neutrino flux with a small additional flux of higher-energy neutrinos. A neutrino detector in Japan, named Super Kamiokande, consists of a tank of 50kton of water, surrounded by photomultiplier tubes. The tubes detect the flash of Cerenkov radiation emitted by a recoiling electron when a high-energy neutrino scatters on it. Calculate the detection rate for neutrino scattering in events per day, if 10-6 of the solar neutrinos have a high enough energy to be detected by this experiment, and each electron poses a scattering cross section=10-43 cm. Hint: Consider the density of neutrino targets "seen" by an individual electron, with a relative velocity of c between the neutrinos and the electron, to obtain the rate at which one electron interacts with the incoming neutrinos, and multiply by the total number of electrons (I've already done this:…arrow_forward
