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...
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...
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!
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...
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...
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.
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...
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 =...
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...
