The work done by the electric field in moving a charge is the negative of the potential energy difference between the two locations, which is the product between the magnitude of the charge q and the potential difference
:
The proton charge is
, and the two locations have potential of
and
, therefore the work is
Large amounts of water do have a big impact on the weather: indeed, it takes less energy to warm/cool land than water.
Therefore, places near large amounts of water tend to have smaller differences in temperature between summer and winter than places far from waters.
Hence, during winter in Puerto Rico, alongside the coast, the temperature will be higher than in the innermost parts of the island.
Answer:
For two polarizing filters to block out all light passing through them, one filter should be rotated 90 degrees from the other.
hope this helps!
Explanation:
100 meters in 9.92 seconds,
=distance/time
=100m/9.92s
=10.0806 m/s
315g/95gmol-1
3.315 moles of MgCl2
