Adead body was found within a closed room of a house where the temperature was a constant 65° f. at the time of discovery the core temperature of the body was determined to be 90° f. one hour later a second measurement showed that the core temperature of the body was 85° 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.)

Ogle–2013–blg–0723 is an exoplanet that is similar to earth in size and proximity to its star. this exoplanet has mass m=4.18×1024kg and radius r=5.66×106m. an astronaut whose weight on earth is w=735n lands on the planet. a. calculate m, the mass of the astronaut. b. calculate gp? , the acceleration due to gravity on the surface of ogle–2013–blg–0723. c. calculate wp? , the weight of the astronaut on the surface of ogle–2013–blg–0723. d. calculate v, the minimum velocity required to put an object into orbit above ogle–2013–blg–0723. e. calculate t, the time required to complete an orbit around ogle–2013–blg–0723.
