This is related to a homework problem but I want to understand it as well. How can a proton break up into a positron and neutron when a neutron clearly has a greater mass than a proton?
We're doing electrochemistry this week and this concept confuses greatly. I know that voltage is the work per unit charge. And electrons move from high potential(is this voltage as well?) to low potential- what is meant by this by the way? How is this related to standard reduction potential? If...
Does anyone know what L is? I'm trying to see if I could find videos on it on YouTube.
On the first question this is what I think- [a;b] is a vector by the way:
1) [2;1]c1+[7;4]c2=[1;0]
[2;1]c1+[7;4]c2=[0;1]
I could have also combined those two by having the linear combination equal to a size...
Thank you for replying. I understand that part, but what I'm having a hard time with is how to determine from different constants which movement(forward or backward) will be favorable(or not so).
I'm currently studying for a test and I'm having problem with this concept:
If I have 3 different Equilibrium constants for different reactions like Kc=103, Kc=1 and KC=10-4, which one's forward reaction is most favorable, and which one's reverse reaction is most favorable?
Maybe it's the...
I'm doing my homework but I'm lost on one thing. Let's say that we have a systems of equations like so:
2x1+3x2=y1
4x1+2x2=y2
Instead of setting it to a constant our teacher sets it to a variable, he says that to be able to compute this, the augmented matrix should look like:
2 3|1 0
4 1|0 1...
Oh sorry about the unit thing. So I have it backwards? It should be the sum of the potential energy of the two parts minus the kinetic energy of the shell. Could I think of it as the absolute value of the change in kinetic energy, although there's no such convention? Thank you again.
O-oh.. ohhh. Wow I feel slow. Thank you very. So it's 410m1+215m2=1440 and m1+m2=5. I understand this part now(although I'm 85% sure on the former's signage, I'm still loose on signage in physics).
After this to find kinetic energy, I'm thinking of subtracting the kinetic energy of the full...

I tried doing MV=m1v1f+m2v2f
I know that the sum of the momentum of the two parts is equal to the the momentum of the the full shell. Since I have two unknowns, I used the conservation of energy. I set used...

Water falls without splashing at a rate of 0.230 L/s from a height of 2.40 m into a 0.630-kg bucket on a scale. If the bucket is originally empty, what does the scale read 2.90 s after water starts to accumulate in it?
