Answer:
City A residents
Explanation:
First we need to calculate the population density of each city. This is calculated by dividing the total population by the total area of the city.
City A has 29455 people and 19.42mi2 of area, so the density is 1516.7 people per mile squared.
City B has 34890 people and 25.4 mi2 of area, so the density is 1373.6 people per mile squared.
If the city with bigger people density is more likely to use bus lines, the city A is the one whose people are more likely to use bus lines, as it has a bigger people density.
Answer:Increase by a factor of 25
Explanation:
We know that magnetic force is proportional to 
where r is the distance between them
Thus 
Where 
=magnetic field
If distance is reduced by a factor of 
then force must increase by a factor of 
because
so 
Answer:
'Incident rays that are parallel to the central axis are sent through a point on the near side of the mirror'.
Explanation:
The question is incomplete, find the complete question in the comment section.
Concave mirrors is an example of a curved mirror. The outer surface of a concave mirror is always coated. On the concave mirror, we have what is called the central axis or principal axis which is a line cutting through the center of the mirror. The points located on this axis are the Pole, the principal focus and the centre of curvature. <em>The focus point is close to the curved mirror than the centre of curvature.</em>
<em></em>
During the formation of images, one of the incident rays (rays striking the plane surface) coming from the object and parallel to the principal axis, converges at the focus point after reflection because all incident rays striking the surface are meant to reflect out. <em>All incident light striking the surface all converges at a point on the central axis known as the focus.</em>
Based on the explanation above, it can be concluded that 'Incident rays that are parallel to the central axis are sent through a point on the near side of the mirror'.
