As more resistors are added in series across a constant voltage source, the power supplied by the source: A) does not change. B)
1 answer:
As series resistors are added, the resistance is added directly so the total resistance will be equal to
Since the power is determined as
We have there that
The power is inversely proportional to the increase in resistance, so it will tend to decrease as more resistors are added in series.
The correct answer is: C.

To develop this problem it is necessary to apply the Rayleigh Criterion (Angular resolution)criterion. This conceptos describes the ability of any image-forming device such as an optical or radio telescope, a microscope, a camera, or an eye, to distinguish small details of an object, thereby making it a major determinant of image resolution. By definition is defined as:
Where,
= Wavelength
d = Width of the slit
= Angular resolution
Through the arc length we can find the radius, which would be given according to the length and angle previously described.
The radius of the beam on the moon is
Relacing
Replacing with our values we have that,
Therefore the diameter of the beam on the moon is
Hence, the diameter of the beam when it reaches the moon is 7361.82m
