Recall that the action spectrum from engelmann’s experiment plotted the rate of photosynthesis (as measured by oxygen production) versus wavelength. in each of the following graphs, the black line shows engelmann’s original action spectrum deduced from the distribution of aerotactic bacteria around the alga. which red line shows the same action spectrum corrected for the unequal number of photons emitted across the visible spectrum?

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.
