Homework Statement One or more external forces are exerted on each object enclosed in a dashed box shown in the figure below. Identify the reaction to each of these forces. (Assume that (a), (b) and (c) occur on Earth while (c), (d) and (e) occur far from any outside gravitational influences...

Homework Statement 2/(x lnx^2) = 1 / (x ln x) That is the answer in the back of my textbook. I have reached 2 ( x ln x^2) , but I do not know why it is = to 1 / ( x ln x ) Homework Equations The Attempt at a Solution I tried to look into precal book to see if I could find...

Homework Statement If the area under y = sin x is equal to the area under y = x^2 between x = 0 and x = k, then k = : Homework Equations The Attempt at a Solution I do not have any idea how to do this problem. So I asked my friends for help, but their methods are different. One of...

To sutupidmath, Thank you! So it should be 2g(x)g'(x), thus the final answer for that question would be P'(3) = 2g(3)g'(3). To Mark44 I got confused a little there because I thought the final answer was different from 2g(x) (which was the wrong answer anyways). Now I redid the problem using...

Homework Statement If P(x) = g^2(x), then P'(3) = Homework Equations The Attempt at a Solution I am not quite sure what g^2(x) means... But my assumption is do the derivative of g^2(x), so it becomes 2g(x), then put the 3 in for x? so the final answer will be 2g(3) ? It looks...

Homework Statement Assume that at 25 C, with AlCl3 as a catalyst, the following equilibrium can be established between the liquids cyclohexane and methylcyclopentane. C6H12 <=> C5H9CH3HCH3 Kc = 0.143 If initially 1.00 x 10^2 g cyclohexane is present, what mass of methylcyclopentane will...

Thank you. I apologize for my careless. I got confused with the book example >.<.

Homework Statement Homework Equations Kc = (Kp)/ (RT)delta n K_c = (K_a)(K_b) (Where a and b are the individual reactions while c is the overall reaction where the coefficients are the same) The Attempt at a Solution The question prior to this one has individual reactions as...

Homework Statement Evaluate the indefinite integral by the method shown in Example 5. (the example in the book is just using the u and du substitution) Homework Equations None. The Attempt at a Solution The question is right below the instruction and after that question is my...

Understood. Thank you! :D

Homework Statement Find the point on the curve y = cos (x) closest to the point (1,1) Homework Equations Tangent line equation y = f'(c)(x-c)+f(c) Distance formula d = SQRT( (x1-x2)^2 + (y1-y2)^2 ) The Attempt at a Solution I have problem doing the f'(c) part. I get stuck when I...

Homework Statement Calculate the wavelength, in picometers, associated with an electron traveling 60.0% of the speed of light. Homework Equations Wavelength = h / (mv) The Attempt at a Solution I know the h value. The v value I believe it is 60.0% of 3.00 x 10^8 But what is the m value...

Thank you! :D

Homework Statement Is it possible to convert ml to grams for a Heat Capacity and Specific Heat type of problem? The problems that I have done so far did not use ml at all. I am stuck with the following problem: A piece of stainless steel (specific heat = 0.50 J g-1 oC-1 ) is taken from an...

What do you mean by physiological differences? Is it body changes? I am not good with biology... :/ My textbook emphasizes on the circulatory system, but they are both open circulatory system. The sites that I look up they have very general information and they aren't helping much. I guess...
