What is the simplest way to solve this question.
Hi, can you elaborate in more detail step # 6 and 7 above? I don't get where you got the numbers 25 and 22 in the following equestions:
Step 6
I1 = 25m1 r2 + m1l22I1 = 25m1d22+ m1l22
I2 = 25m2r2 + m2l22= 25m2d22 + m2l22
Thanks!

- That did answer a lot of questions. Thank you. But where do you derive the equation E=(K|q|)/r? My book says E=(K|q|)/r^2. I tried re-arranging some equations to get your equation, but I can't figure it out. Thanks.arrow_forwardPlease answer within 90 minutes.arrow_forwardAnswer question 21, 22 showing fully all the steps. Solution should be simplified and easy to understand as much as possible!arrow_forward
- That still doesn't answer my question. How did you take (m1 + m2)2 + (m1 + m2)2 and get (m1 + m2)2. Where did the extra (m1 + m2)2 go? There were two of them. Now there's suddenly one. That's the step I've been confused about since the beginning. I understand the physics. I'm having a problem with the algebra.arrow_forwardA star, which is 2.3 x 1020 m from the center of a galaxy, revolves around that center once every 2.3 x 10% years. Assuming each star in the galaxy has a mass equal to the Sun's mass of 2.0 x 1030 kg, the stars are distributed uniformly in a sphere about the galactic center, and the star of interest is at the edge of that sphere, éstimate the number of stars in the galaxy. Number i Unitsarrow_forwardIdeally I would like help with all questions if someone is able and willing to help ( I had to post them all together since they are related and so the expert could better understand). If not, I specifically would like help with the last question (question 33). Thank you very much in advance!arrow_forward
- Kindly give me a detailed answer in a clear handwriting of all the subparts by mentioning the subpart's name. It is one whole question. All the subparts are related. Take your time solving this. I am attaching the full question. All the questions are related. This is my second time uploading these questions as I got wrong answers previously. So kindly answer this one by following the given instructions. I will upvote if the answer is correct.

- The farthest objects in our Universe discovered by modern astronomers are so distant that light emitted by them takes billions of years to reach the Earth. These objects (known as quasars) have many puzzling features, which have not yet been satisfactorily explained. What is the distance in km of a quasar from which light takes 3.0 billion years to reach us ?arrow_forwardI am a bit confused by how you did the first one, and what the answer is.arrow_forwardthis is very confusing.arrow_forward
