Homework Statement The question gives me a diagram and is asking me to find the direction of the current through a resistor. I understand that current always flows from positive to negative terminal of the power source but the thing is, I'm given 3 batteries and a resistor (which I don't...

Nevermind. I figured it out :D The answer is 863/3... just fyi.

Homework Statement I am given the following two functions: y=x3-13x2+40x and y=-x3+13x2-40x I need to find the area bound between the above two functions. Homework Equations Integrals! The Attempt at a Solution I don't know how to do this as there is 3 points of intersection...

Homework Statement Containers A and B in the figure hold the same gas. The volume of B is four times the volume of A. The two containers are connected by a thin tube (negligible volume) and a valve that is closed. The gas in A is at 300 K and pressure of 1.0*105Pa. The gas in B is at 400 K and...

...Nevermind. I realized that it doesn't matter what the values for specific heat capacity and thermal conductivity... if the oven is maintained at the given temperature, all objects will be the same upon removal if they are allowed to reach thermal equilibrium.

Homework Statement To summarize, I am given 6 objects and their corresponding specific heat capacity and thermal conductivity values. All objects have the same mass. The question is asking me to rank the objects based on temperature if they are put in a hot oven until they reach thermal...

Awesome! Thanks so much :)

Hey, thanks for your reply. Once I got a=xx, I differentiated implicitly... ln(a) = x ln(x) da/dx 1/a = [ ln(x)+1 ] da/dx = xx (ln(x)+1) And then in the original function f(x)= a ln (3x-6), once I had to differentiate a, I just substituted in da/dx. I'm just curious, when you said that...

Homework Statement Differentiate f(x) if f(x)=xxln(3x-6) Homework Equations None The Attempt at a Solution The problem in f(x) is the xx so what I did was let a=xx and differentiated a with respect to x. I ended up with da/dx= (ln(x)+1)xx. Afterwards, I modified f(x) by...

Homework Statement A 58 kg person is in a head-on collision. The car's speed at impact is 13 m/s. Estimate the net force on the person if he or she is wearing a seat belt and if the air bag deploys. For some reason, I can't seem to get the correct answer to this question... I have no idea...
