Answer:
b Wind blowing West to East away from horse latitudes
Explanation: prevailing Westerlies are winds which blows away from the horse latitudes, this type of wind blow towards the poles between latitude 30 degrees to latitude 60degrees.
Prevailing Westerlies are known to be strongest in the winter months in the and weakest in the summer months
They are also very strong when the pressures are low over the poles and also very weak when the pressures are high over the poles.
Gravitational potential energy above a reference level is M G H .
In this story,
-- M = 25kg
-- H = 15m
and if the story takes place on Earth, then
-- G = about 9.8m/s².
PE = (M) (G) (H) = (25) (15) (9.8) = <em>3,675 joules</em> .
That's the gravitational potential energy acquired by the suitcase
in the process of being lifted 15 meters straight up.
Sadly, human physical effort is far from 100% efficient, and the woman in
the story has to expend a lot more energy than that just to lift the suitcase
up the stairs. AND PLUS don't forget that she also has to come up with
enough additional energy to increase the potential energy of <em>her own</em> mass,
no matter how dainty it may be, by 15 vertical meters' worth.
Now 25 kg = about 55 pounds,
and 15 meters = about 50 feet, or something like 4 to 5 stories
You can be sure that some beads of glow highlight her forehead
by the time she's done with this job.
