Answer:
one sister, one half-brother, and three cousins.
Explanation:
Kin selection theory also called inclusive fitness theory describes the self-sacrificial behaviour of organism, animal or individual to ensure survival of closely related family at the detriment of the individual's survival in order to preserve genetic fitness or survival and reproductive success of such individual. Therefore saving one sister, one half-brother, and three cousins will preserve the genetic lineage and reproductive success of the genome of interest
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'.
Answer:
Below
Explanation:
First, we need to convert the dimension from cm to m before plugging it into the equation:
32 / 100 = 0.32 m
10 / 100 = 0.1 m
You can use this equation to find the pressure exerted on the ground
Pressure = Force / Area
Plugging our values in.....
Pressure = 16 Newtons / (0.1)(0.32)
= 16 Newtons / 0.032
= 500 N/m^2
Hope this helps! Best of luck <3
The frequency is the number of complete oscillations per second. One complete oscillation corresponds to 1 push. Converting the time into seconds:
we can find the frequency of the swing:
