Solar energy is free and renewable.  

Its efficiency is determined by the photovoltaic or heat-exchanging equipment used, and the efficiency of the infrastructure built to interconnect them.  None of that depends on the time of the year.  For a given amount of solar energy absorbed by the collector, the amount of useful output energy doesn't change with the season.

if a torque of 55.0 N/m is required and the largest force that can be exerted by you is 135 N what is th e length of the lever a
Whitepunk [10]

Answer:

r=0.41m

Explanation:

Torque is defined as the cross product between the position vector ( the lever arm vector connecting the origin to the point of force application) and the force vector.

\tau=r\times F

Due to the definition of cross product, the magnitude of the torque is given by:

\tau=rFsin\theta

Where \theta is the angle between the force and lever arm vectors. So, the length of the lever arm (r) is minimun when sin\theta is equal to one, solving for r:

r=\frac{\tau}{F}\\r=\frac{55\frac{N}{m}}{135N}\\r=0.41m

Suppose you have made the following hypothesis:
Blizzard [7]

Answer:

Explanation:

You could look up the shark population near specific coral reefs. You could also go the simple route and say something like, "sharks eat fish so, sharks will go where the fish are and if there are fish in the coral reefs, (which there are) they would be most likely to go there".  I know this may not be the answer you were looking for but its the best I've got.
