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.)

Which object is most likely represented by a dot?

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
