ok I've resolved the problem. Both the book, and their online website have two distinct wrong equations to use.. The correct one would involve flipping the Tenv^4 with the T^4.. so it would read (T^4 - Tenv^4). So, I dub this problem as resolved in case anyone was interested.
Step1: what does Newton's third law state?
Step2: Draw the field lines radiating outward as if you could visually see the field itself. Start at one end and to the other using your right hand rule. Do this for both wires as they are described in the problem. Do the field lines touch...
Additionally you might want to get into the habit of writing down the x (cross)-format. All that X (cross) means is that one part is crossing over to another part, like a swinging door that crosses from one room to another each time it is pushed open or closed.
I know I'm not a mentor or anything but.. Write down Newtons third law.. what does it say aka what does it really mean? Now write down your wire equation again.. what does it say? Are they the same or are they different? What does your intuition say regarding the difference between the two?
Ok I just did it in mathmatica .. and it gave the same answer .. If
my intuition is incorrect then the only possible solution would be
that P1 is somehow =(\sigma) (\epsilon) A1((24+273)4) ... but that's not how the question reads
1. A solid cylinder of radius r1 = 2.3 cm, length h1 = 4.2 cm, emissivity 0.88, and temperature 24°C is suspended in an environment of temperature 55°C. (a) What is the cylinder's net thermal radiation transfer rate P1? (b) If the cylinder is stretched until its radius is r2 = 0.52 cm, its net...
A while back I recall reading an article regarding artificially forcing electron particle waves into the surrounding nucleus of an Atom and that the result would shrink the size of the atom. Can an Atom hold more than the normal amount of electrons, if so is there a maximum?
I Have a question. I have this project presentation that requires the use of a Tri-Poster. The theme of the project is outer space. For maintaining professionalism would it be considered ok to design the background with stars and planets to help keep that space feel, or should I leave it with...
1.
here is what I've obtained
Data:
3.
Increasing (με) (μin/in) and decreaseing (με) (μin/in) are both STRAIN
[Increasing σ (psi)] and decreaseing σ (psi) are both STRESS]
My question is. From the directions above, is it asking for a plot of Stress vs...
not integrated, just broken down is all as Berkeman has said. for instance if the resistance was 8 and the length was 4 times the original length. One method of solving out what the resistance would be is to take the length 4 and divide by 1/4 = 16 and then multiply 16 time 8 which = 128 ...
I have no doubt that the second method was faster for most, but we did a quiz similar to this problem and I regurgitated the first method in less than 30 seconds and was beat only by one other person in time. (thats only because he was sitting in front of the professors desk). I didn't even...
