A coulomb is a very large unit of charge and is therefore very hard to obtain. However, fairly large currents of several amperes (coulombs/second) are very common. How is this possible?

switching action at time t=0.
In each case, how to I write the differential equation that must be solved to find the transient or natural circuit response?

dI(t)/dt + 6I(t) = 10

d^2I(t)/dt^2 + 5I(t) = 24

Many Thanks for your help :)

We are essentially complex molecular machines. That's the hardware. What exacly is the software?

Let me explain the question a little more. Jack is alive at 10:24. By 10:30, he dies in his sleep. All the molecular machines are sill there. The energy is also there. What is different immediately after he dies? Yes, I know he's now dead. So, what happened?

1 2 4 8 16 32 64 128 . imagine it is numbers in a rule. the question is estimate the positions of 5,25,10,20,40,50,80 n 3. i think the positions can be find by diving the place.eg. 2,3,4 then 8-4=4 n then divide by 2 u get 6 so you can estimate where is 5,6, or 7. my question is what there is got to do with exponential or logarithm. basically, you can find the number positions by dividing them. if the area is big, you have divide many times n then you can find the position. if anyone understand the link between exponential or logarithm with the position estimation question pls help me

I can not prove the followng:

sign of integration(-infinite,infinite)
{[cos(x)/(x-w)]dx};
w----a constant;

the answer is
pi*i*e^(i*w) when Im*w>0
-pi*i*e^(-i*w) when Im*w<0

can anybody help,show me the detailed all the proof steps?
my email is:chrisyouger0@yahoo.com

When we calculate standard deviation, we'll square the differences first in order to get variance and then take the square root of it. But why don't we cube differences first (or differences to the power of 1.2 or whatever) and take cube root(or whatever root)?

Ok, my average speed driving to my cabin is 55 miles per hour. Doing so, it takes me four hours to get there. My boyfriend Eric says that I could save at least half an hour if I drove 65 miles per hour. Is that correct? How long will it take me to get there going 65 miles per hour and how much time will I really save. Thanks so much.

A more accurate phrasing of the question is: "Are you open to believing in the paranormal, or do you immediately deny everything that can't be explained scientifically?"

I have an upcoming exam, and I am fairly sure this question will crop up in it;

'Solve sinx = 0.5'

Now I know what the answer is. x = 30. But I need to be able to prove it, and I have no idea how!

Compare and contrast the value of humans with non-humans entities (an endangered species, or endangered habitat).

1)What is the ethical basis for your reasoning?
2)How do you see humans in its relationship to nature?
3) Does humanity have a special moral status because of its higher intellect? Rights? Responsibilities?
