Animals in cold climates often depend on two layers of insulation: a layer of body fat [of thermal conductivity 0.200W/(m⋅K) ] surrounded by a layer of air trapped inside fur or down. We can model a black bear (Ursus americanus) as a sphere 1.60m in diameter having a layer of fat 3.90cm thick. (Actually, the thickness varies with the season, but we are interested in hibernation, when the fat layer is thickest.) In studies of bear hibernation, it was found that the outer surface layer of the fur is at 2.80∘C during hibernation, while the inner surface of the fat layer is at 30.9∘C a) What should the temperature at the fat-inner fur boundary be so that the bear loses heat at a rate of 51.4W ? b) How thick should the air layer (contained within the fur) be so that the bear loses heat at a rate of 51.4W ?

Which of the following is a type of antimatter created in some nuclear fusion reactions within stars?A. photon
B. positron
C. neutrino
D. helium-4

Answers

A type of antimatter created in some nuclear fusion reactions within stars is B. Positron. Antimatter is composed of antiparticles, and is considered to be the opposite of matter. Its antiparticles have the same mass as ordinary particles, but they have the opposite charge. When matter and antimatter come into contact, annihilation or destruction occurs.

Answer:

The answer is B i just took the test and got it correct:)

Explanation:

Find the percentage of the total work lost to friction if 28.7 J of work is put into pushing a block up a ramp resulting in 14.2 J of stored potential energy at the top.

Answers

Answer:

14.5 joules

50.5 %

Explanation:

Energy initial +work= energy final

28.7 + work = 14.2

friction did - 14.5 joules of work so percantage of work lost is just 14.5/28.7 *100 or 50.5 %
