Explanation:
As an object falls toward earth, the potential energy of the object: Decreases
<h3>What is the gravitational potential energy towards the earth?</h3>
In this case, the formula for the Potential energy is:
E = Em + Ek + Eg
Where;
Em is energy due to mass
Ek is kinetic energy
Eg is energy due to gravity
Thus, as the potential energy falls toward earth, Eg will approach 0, which will decrease its amount.

Considering the data in the question, the focal length of the objective lens that will give a total magnification of 200x is <u>0.8cm focal length.</u>
The whole question is:
You are using a microscope with a 10x eyepiece. What focal length of the objective lens will give a total magnification of 200x? Assume a length L = 160mm.
<h3>How was the answer derived?</h3>
Given that total magnification is 200
And the Assume length is 160
Since we used a microscope with a 10x eyepiece, the magnification would be divided by 10.
=> 200 ÷ 10 = 20.
Also, the focal length is measured in centimeters or meters; we would change the millimeters of focal length to centimeters. Therefore, we have 160 ÷ 10 = 16
The formula for the focal length of the objective lens = assumed length ÷ total magnification.
=> 16 ÷ 20 = 0.8cm.
Hence, in this case, it is concluded that the correct answer is "0.8cm."

Answer:
Starting in 2014, Penn Foster began introducing online proctoring as an additional option to a face-to-face proctor. Since then, thousands of remote proctored exams have been taken on Penn Foster’s systems, with less than 1% of proctored events flagged for infractions. What does this mean? It means that within this exam environment, students are unlikely to cheat. To simulate a traditional test-taking environment, the student is given strict guidelines regarding what they can and cannot do, including rules for what they are allowed to bring into the room with them, and when they are allowed to leave. The student is recorded via webcam while the testing system controls what the student sees on their screen. For additional identity verification, students are asked to present their license or ID to the webcam. The remote proctoring platform audits the recordings after the fact, and contacts Penn Foster with any reports of infractions.
For students who are unable to take remote proctoring, they must use paper proctored exams. In this case, the student finds someone who meets the requirements to proctor the exam, and Penn Foster verifies the individual. Penn Foster continues to work to switch over all exams to the remote proctor option, via an ongoing programmatic roll-out
