I Volunteer I Medical Resources I PIRG Program I PHV2130 Reading list Diffusion of molecules through a surrounding medium is characterized by a diffusion constant, lambda. This diffusion constant has dimensions of L"2/T. When we study diffusion later this semester, we will see that the diffusion constant is related to the average distance the molecules travel, lambda, and their average speed v. Since lambda is a distance, it has dimensions of L, and v has dimensions of UT. Using this information, which expression below could be valid (correct dimension) for the diffusion constant in terms of lambda and v? A) lambda / v B) v / lambda C) lambda x v D) 1 / (lambda x v) E) v"2 / lambda OA W Quiz: HW 2 X - C canvas.wayne.edu/courses/163450/quizzes/406715/take G PAUSI Apps M Gmail YouTube Wayne State Univer..

The masses of the comet and the Sun, m1 and m2, are fixed and G is a constant number. When the comet is some distance r from the tion Sun, the force of the Sun's gravity on the comet is F. When the comet's distance from the Sun increases to 2r, what is the force of the Sun's gravity on the comet?

Volunteer Medical Resources PIRG Program PHY 2130 Reading list Medical researchers have found a way to grow new skin from stem cells created from a patient's own skin. If a patient has been burned and needs a skin transplant for 50 cm of skin, using your general knowledge of the average size of a mammalian cell, estimate the number of cells that would need to be grown to cover the transplant area. dings es O 2 x 10 13 tion O 3 x 10^11 O 3 x 1019 0 5 x 10^5 O 2 x 10^7 se Not saved Submit Quiz
