1 answer:
It can be expected in this city that the hours of sunshine will significantly increase after the month of July
<h3>What is the trend in the hours of monthly sunshine in Addis Ababa?</h3>The monthly hours of sunshine in the city is the average of daily sunshine in a month.
The trend as seen on th graph shows that monthly hours of sunshine is maximum between the months of December and January. Afterwards the monthly sunshine hours decreases.
Therefore, it can be expected in this city that the hours of sunshine will significantly increase after the month of July.

Answer:
A
Explanation:
The figure shows the electric field produced by a spherical charge distribution - this is a radial field, whose strength decreases as the inverse of the square of the distance from the centre of the charge:
More precisely, the strength of the field at a distance r from the centre of the sphere is
where k is the Coulomb's constant and Q is the charge on the sphere.
From the equation, we see that the field strength decreases as we move away from the sphere: therefore, the strength is maximum for the point closest to the sphere, which is point A.
This can also be seen from the density of field lines: in fact, the closer the field lines, the stronger the field. Point A is the point where the lines have highest density, therefore it is also the point where the field is strongest.
