Answer: find the attached figure for a and b
Explanation:
A) The second figure depict electric field lines and equipotential lines for two equal but opposite charges. The equipotential lines can be drawn by making them perpendicular to the electric field lines. The potential is greatest (most positive) near the positive charge and least (most negative) near the negative charge.
B) The figure attached depicts an isolated point charge Q with its electric field lines in blue and equipotential lines in green. The potential is the same along each equipotential line, meaning that no work is required to move a charge anywhere along one of those lines. Work is needed to move a charge from one equipotential line to another. Equipotential lines are perpendicular to electric field lines in every case.
Please find the attached file for the figure
Answer:
Large binocular telescope, Keck 1 telescope, Hobby-Ebberly telescope, Subaru telescope, Gemini North telescope, Magellan 2 telescope
Explanation:
How much light a telescope can collect depends on its diameter, since in a bigger area more photons will be collected.
Remember that in a circle the area is defined as:
(1)
Where A is the area and r is its radius.
However, the radius can be determined by means of its diameter.
(1)
Where d is its diameter.
An example of this is when a person is collecting raindrops with a bucket and with a cup. Since the bucket has a bigger area than the cup, it will collect more raindrops by unit of time. In this scenario the raindrops represent the photons.
To determine the light collecting area of each telescope, equation 2 will be replaced in equation 1.
(3)
Case for Large binocular telescope:
For the second mirror will be the same value
Case for Keck 1 telescope:
Case for Hobby-Ebberly telescope:
Case for Subaru telescope:
Case for Gemini North telescope:
Case for Magellan 2 telescope:
Hence, they may be rank in the following way:
Large binocular telescope, Keck 1 telescope, Hobby-Ebberly telescope, Subaru telescope, Gemini North telescope, Magellan 2 telescope.
