no not what I mean, on the B side, i have all the other sign matching up except the 20v so multiply by -1 won't make it correct, but that's not my question I just want to know how they got their currents for each of the meshes
What do you mean? That is a pratice example so I'm assuming their answers and equations are correct and if mine doesn't match up then I'm doing something wrong

So I'm trying to get a better understanding of KVL by looking up practice problem and I'm having some difficulties. I'm attempting to do this problem
my first step is to get an equation for Ia (32v-10ia+8ib = 0) an Ib (12ib+20v-8ia =...
I have a 8mm diameter glass tube willed with water that have a bulge outward above the top.
I know that the preasure inside the bulge is higher than the outside (not postive as to why, probably due to it being in a liquid compare to the atmophere)
the question is:
1. how do I calculate the...
oh, so it would be pushed up since gravity accel is negative, right?
2. I just think about it, since all the variable in the equation is positive, and the negative mass is the only negative, so the force would end up being negative, right?
I'm in Physics 1 and this is an extra credit I need
1. Homework Statement
From time to time, it is amusing to consider extending physics to unusual circumstances or values of parameters. Consider an object with a negative mass. How would it behave? How would we be able to detect it if it...
Linear work is F*D and rotation is 1/2Iω2, but if a problem as me rotational energy (Rotation worl = KE?) of a wheel and I have the linear work, can I just set Wrotation=Wlinear?
