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.
Answer:
80%
Explanation:
Thermal efficiency is a measure of the extent to which a heat engine is able to convert to other form. It is measure in percentage.
Thermal efficiency = 
× 100%
Where 
is the input energy and 
is the output energy.
Given that: = 2400 J and = 3000 J, therefore:
Thermal efficiency = 
× 100%
= 80%
The thermal efficiency of the engine is 80%.
