Answer: 2.5 feet is already in 2 sig figs, in inches it would be 30. (30 including the deciaml) and in cm it would be 76
Explanation:
Explanation:
Using Beer-Lambert's law :
Formula used :
where,
A = absorbance of solution
c = concentration of solution
l = length of the cell
= molar absorptivity of this solution
According to question:
A = (C) : absorbance measured by the spectrometer
c = (B) : concentration, in mol/L, of the stock solution from which the sample was made
l = (A): pathlength of light through the cell
ε = (D) : molar absorptivity, a constant unique to that substance at that wavelength
Answer:
Option (A)
Explanation:
The temperate forest usually covers the tropical and the taiga region. The trees in this forest region experience all the four seasons namely summer, autumn, winter and spring. It comprises approximately 25% of the total forest-covered region on earth. The leaves of these trees change color during the autumn season, which eventually falls off during the winter season, and again, new leaves grow back during the spring season. This enables the plants to survive and go through the cold temperature in the winter.
Thus, the correct answer is option (A).
