- We need clear solution step by stepDescribe about the thermal hazard and shock hazard.A dead body was found within a closed room of a house where the temperature was a constant 70° F. At the time of discovery the core temperature of the body was determined to be 80° F. One hour later a second measurement showed that the core temperature of the body was 75° F. Assume that the time of death corresponds to t = 0 and that the core temperature at that time was 98.6° F. Determine how many hours elapsed before the body was found. [Hint: Let t1 > 0 denote the time that the body was discovered.] (Round your answer to one decimal place.)

- A dead body was found within a closed room of a house where the temperature was a constant 71° F. At the time of discovery the core temperature of the body was determined to be 81° F. One hour later a second measurement showed that the core temperature of the body was 76° F. Assume that the time of death corresponds to t = 0 and that the core temperature at that time was 98.6° F. Determine how many hours elapsed before the body was found. [Hint: Let t > 0 denote the time that the body was discovered.]The radioactive gas krypton-85, produced by nuclear power plants as well as volcanoes, is present in trace amounts in earth’s atmosphere. Its half-life is 10.8 years. Suppose a volcano released 250 g of krypton-85 in an eruption. How much would remain after (a) 10.8 years, (b) 15 years, and (c) 50 years?

- A 1.00-MT bomb exploded a few kilometers above the ground deposits 25.0% of its energy into radiant heat. Find the calories per cm2 at a distance of 10.0 km by assuming a uniform distribution over a spherical surface of that radius.can i get an explantion how the process happened? please? thank you!!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. What is the percent error in your calculation of gold needed if you ignored the change in volume to the tank created by applying the titanium layer…
