Answer #1

ANSWER: No wecannot use a constant value for the effective plume rise, we need to adjust because germination will not be proper as a) there is no proper supply of oxygen for respiration

                            b) there is an insufficient pushing force in the embryonic part i,e hypocotyl or epicotyl, to break through the upper layer of the soil.

Explore the dependence of sunlight on earth-sun distance. The solar constant, S_0 is the solar radiation at zero zenith angle at the mean earth-sun distance, R_m. As we learned in class the intensity of solar radiation decreases with the square of the distance. Use matlab to devise a function that calculates the daily averaged solar radiation as it depends on earth-sun distance (ignore seasonal changes in the sun's angle) through the course of one year. Use for the eccentricity the...

One way to roughly measure the focal distance of an unknown converging lens is to use it to focus a far-away object. for example, you can focus an image of the overhead light fixture onto the floor. then the distance from the lens to the floor is approximately the focal length. a. draw a ray diagram for this situation and discuss why it is a reasonable way to approximate the focal length.    b. Do you expect this method to...
