I'm in my second year in college and I've taken an Operating Systems course that has a project component. I've been assigned Memory Forensics as my project topic. On approaching the professor I was told that I need to attempt to attack the Linux Kernel ( I'm guessing that means I need to write...

The depletion layer is formed by the movement of electrons from the n to p side and holes from p to n side of the diode. The layer consists of positively charged donor ions close to the n side and negatively charged acceptor ions close to the p side. When in equilibrium,the barrier potential...

So what I've done is wrong. Where exactly should the change be?

Homework Statement Two capacitors of capacitances 3μf and 6μf are charged to potentials of 2V and 5V respectively. These 2 charged capacitors are now connected in series.Find the charge and potential difference across each of the capacitors now. Homework EquationsThe Attempt at a Solution...

Oh ok. I'll stick to the browser then. Sad.

Introductory physics homework was what I tried first . But none of the others work either.

I just got the physics forums app. I am logged in and am inside the desired forum but I cannot find any create thread button anywhere. I found a create new topic button, but it says I don't have the permission to create a topic inside this forum. I don't understand why as I am most definitely...

Thank you, @SammyS and @Delta² for the legal and illegal solutions respectively. Alas, we don't learn lots of beautiful things in school. and @conscience for highlighting the daily horrors of the OP. We sometimes get petrified when we hear completely fresh concepts that we have never encountered...

Yes, that is within my school level jurisdiction. It works and I got option c) which is right.

No, we were not taught anything like that. Is that the only way, whatever it is?

Homework Statement Let ρ(r)= Qr/πR4 be the charge density distribution for a solid sphere of radius R and total charge Q.For a point 'P' inside the sphere at distance r1 from the centre of the sphere, the magnitude of electric field is ? A) 0 B) Q/4πε°(r1)2 C) Q(r1)2/4πε°R4 D)...

Homework Statement Solution set of the inequality (cot-1(x))2 -(5 cot-1(x)) +6 >0 is? Homework EquationsThe Attempt at a Solution Subs cot-1(x)=y We get a quadratic inequality in y. y2-5y+6>0 (y-2)(y-3)>0 Using the wavy curve method, the solution set is...

Right.Got it. Nothing disturbs me anymore. Thank you for the help. Peace.

Finally... I shall summarize it again, please check if it's right. √(1-cos2θ) = +sin(θ) , as (π/3)≤θ≤0. This part is wrong, as the range of arccos is [0,π] and since (π/3)≤θ≤0, θ-(π/3) is -ve and I can write only the +ve (π/3)-θ. Just one more question. Why are the inequality signs being reversed?

Yes, I get that, but even if sin θ is negative , it results in the final answer to be 2θ + (π/3). Which is 2cos-1(x) + (π/3). So considering both cases of sin(θ) being positive or negative doesn't give me the final answer as π/3. It seems as though the only way is to write this bit as, cos (...
