Good because I know I am giving them good pointers, or feedback on whatever the situation may be.
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:
Velocity
Explanation:
Speed is how fast something moves.
Velocity is how fast it moves and in what direction it moves in.
Acceleration is the change in how fast it moves. I.e. if it speed up or slows down.
Here we are given the speed of the train (75mph) and the direction (north), therefore it is velocity.
Hope this helped!
I'm a pastor's kid and I ask myself that question all the time, and what helps me the best is to go to church and listen to the pastors, listen to praise and worship music, and what I would recomend the most is downloading the bible app on your phone, because most often we are on our phones than reading paper, and personally I've read more of the bible on my phone than the actual book.
