Explanation:
Below is an attachment containing the solution.
Answer:
800
Explanation:
Focal length of telescope, F = 200cm
Focal length of eyepiece, f = 0.25
The magnifying power of a telescope is given as the ratio of the focal length of the objective of the telescope to the focal length of the lens. Mathematically:
M = F/f
Therefore, when F = 200cm and f = 0.25cm:
M = 200/0.25
M = 800
As speed changes, wavelength changes, and frequency remains the same
Answer;
The above statement is true
Human impact on one system leads to changes in more of Earth’s systems.
Explanation;
Events can occur naturally, such as an earthquake or a hurricane, or they can be caused by humans, such as an oil spill or air pollution. An event can cause changes to occur in one or more of the spheres, and/or an event can be the effect of changes in one or more of Earth's four spheres.
Human impact on one system leads to changes in more of Earth’s systems because things like carbon and methane emissions affect the environment, which affects all plant and animal life.
