A). The sun is highest in London, but will not pass the ship
for another 5 hours.
Since the sun moves from east to west, the ship must be
5 hours west of Greenwich.
Each hour of sun motion is 15° of longitude.
The ship's longitude is (5 x 15°) = 75° West.
The ship may be sailing down Columbia Boulevard
in Maple Shade, New Jersey.
B). The latitude at Buffalo's City Hall is 42.887° North.
Polaris is always within about 2/3 of a degree of that angle
above the northern horizon, when viewed from City Hall.
Choice 2) is the most appropriate.

The internal energy of an ideal gas is given by:
where
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas
k=3 for monoatomic gases, k=5 for diatomic gases
In this problem, we have n=3.0 mol of a diatomic gas (k=5) at T=288 K. Substituting these numbers into the equation, we find the internal energy of the gas:
