Answer:
Solar flux that incident on it is given as
S = 160 W/m/m
Now we know that the area of solar panels is given as
A = 10 m^2
So total solar power received by solar panels is given as
Power Received = (Solar flux) \times (Area)PowerReceived=(Solarflux)×(Area)
P = S\times AP=S×A
now here we have
P = 160 \times 10P=160×10
P = 1600 WP=1600W
now we know that efficiency of the solar panels is 20%
so total output power will be
efficiency = \frac{P_{out}}{P_{in}}efficiency=
P

0.20 = \frac{P_{out}}{1600}0.20=

=320W
Answer: The last option.
Explanation: The precautionary principle would be considered to be most strictly applied where the precautionary measure is most disproportionate to the given risk. In all but the last option, there are either measures taken in response to concrete problems, or the precautionary measures are actually relaxed. In the last option, though, there are merely “fears” that antibiotics and growth hormones could cause harm (no experimental evidence), but the school board still takes the strict precautionary measure of mandating that schools only serve organic milk.
