Glycerine in water diffuses along a horizontal column that has a cross-sectional area of 2.0 cm2. The concentration gradient is 0.03 kg/m4, and the diffusion rate is found to be 5.7e^-15kg/s. Determine the diffusion coefficient. m2/sc
a. 1.9e-13 m2/s
b. 1.7e-16 m2/s
c. 9.5e-10 m/s
d. 3.4e-20 m2/s
e. 3.8e-17 m2/s

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem

Arope has one end tied to a vertical support. you hold the other end so that the rope is horizontal. if you move the end of the rope back and forth with a frequency of 4 hz, the transverse wave you produce has a wavelength of 0.5 m. what is the speed of the wave in the rope?
