1. ### Programs Changing my major, not sure which physics to take?

Hello everyone, After long deliberation I decided that my major isn't for me, I would rather do Chemical Engineering. I have taken Algebra Physics I and II and gotten A's in both. I have the option of taking General Physics I or Honors Physics I. General Physics I is a calculus-based...
2. ### Conceptual Question Dealing with Confidence Intervals

Homework Statement 1.) When we collect more data for our confidence interval (A) Confidence Increases (B) Confidence Decreases (C) n decreases (D) The length of the interval decreases (E) The length of the interval increases 2.) We wish to determine a confidence interval for the population...
3. ### Analytical Problem with Coulomb's Law

Sorry, I did have the units on my scratch work. I tried it on my TI-83+ and I got 2.14 x 108, so it must have been me using the google calculator! Thank you everyone!
4. ### Analytical Problem with Coulomb's Law

Homework Statement Consider a parallel universe where the laws of nature as we know them are different, and aqueous solutions can have an excess charge. Two beakers are separated 1.20 meters and each contains 0.300 L of an aqueous solution of 6.40 × 10-6 M excess charge. One beaker has a net...
5. ### Stumped on a Molarity problem

Yes, thank you. I caught my mistake. Just some careless thinking on my part. Thank you for the response.
6. ### Stumped on a Molarity problem

Homework Statement Calculate the molarity of a solution made by adding 35.5 mL of concentrated ammonia (28.0 % by mass, density 0.880 g/mL) to some water in a volumetric flask, then adding water to the mark to make exactly 250 mL of solution. (It is important to add concentrated acid or base...
7. ### Deeper learning in Physiology?

It was not required and I took it over the summer at community college. To be honest we learned the same as calculus based. The professor made us use calculus to derive if we wanted to use a formula instead of memorization. I don't feel like retaking it also.
8. ### Deeper learning in Physiology?

T Thank you. But I have already taken calculus I, II, and III
9. ### Deeper learning in Physiology?

Ohh, that seems to be what I'm looking for! Do you have any recommendations? And are there any requisites for reading those?
10. ### Deeper learning in Physiology?

I'm able to understand about 60% of it. I never learned about Bernoulli's principle specifically, but I inference the concept of pressure.
11. ### Deeper learning in Physiology?

I have no idea where to post this, but I figured this is the most relevant place. I'm sorry if it's in the wrong section. I am a Pharmacology and Toxicology major at a large state school. I was only required to take physics I and II. (algebra based) At first I thought that was fine, but I...
12. ### Atwood Machine Problem

Thank you so much for the help!
13. ### Atwood Machine Problem

It would have to be 0 Newton's. If I'm correct about that, then I already assumed that, however I rethought my approach on part a and b. I redid the FBD's for (a) and (b) and added the two equations for Newton's second law, and the tensions canceled each other out, leaving me with w1 - w2 =...
14. ### Atwood Machine Problem

The system would change where object 1 would be "in the air" correct?
15. ### Atwood Machine Problem

1. A 77.00 Nt object (denoted as object 1) rests on the ground. A light cord is connected to this object which runs vertically upward over a light frictionless pulley and is attached to another object denoted as object 2. a) Calculate the force that the ground exerts on object 1 if object 2 is...
16. ### Two vehicles moving in opposite directions bonus problem

I could see my professor giving us a bonus question like that to be honest. His name is Doc Al as well...what a coincidence! Thank you for your confirmation, I needed those 6 points!
17. ### Two vehicles moving in opposite directions bonus problem

Thank you again, I hope I didn't make you feel like you have too lol. To be honest its probably something like a math error.
18. ### Two vehicles moving in opposite directions bonus problem

I must have messed up somewhere. Thanks anyway.
19. ### Two vehicles moving in opposite directions bonus problem

280 = vib(4) + 1/2 (ab)(4)2 160 = vib(3) + 1/2 (ab)(3)2 So I solved for ab and I got 11.85 / vib = ab I plugged that into the 280 = vib(4) + 1/2 (ab)(4)2 equation and I got an answer of 0.34 m/s. Which still doesn't seem right. But continuing on I plugged 0.34 m/s into 280 = vib(4) +...
20. ### Two vehicles moving in opposite directions bonus problem

Sorry that was a typo on my part. What I had on paper was 160 = vib(3) + 1/2 (ab)(3)2
21. ### Two vehicles moving in opposite directions bonus problem

I believe so, since the problem says that both are a constant.
22. ### Two vehicles moving in opposite directions bonus problem

I copy and pasted the file that the professor gave us. I can upload the pdf if you would like.
23. ### Two vehicles moving in opposite directions bonus problem

Homework Statement Vehicle A and Vehicle B are moving in opposite directions on the NJTP. Vehicle A is heading south toward atlantic city while vehicle B is heading north towards Hoboken. In situation 1 and 2 described below, at t = 0s both vehicles are at a distance of separation of 400m...
24. ### Extra Credit Question for my class, I don't think I did it correctly.

Sorry, the pictures should read 1, 2, 5, 4, 3

26. ### I'm not sure how they got this answer

Oh, thanks. It must have been a calculator error on my part because I had the same equation set up, only I got 0.0155!! Note to self, don't use dollar store calculators :rofl:
27. ### I'm not sure how they got this answer

Homework Statement I'm not sure how they arrived at that number, or how they "scaled it." Thanks!
