If the current density in a conducting medium is given by determine the corresponding charge distribution pv(x, y, z; t).
Continuity equation for electric charge. Suppose there is a volume current density given by 7-(i)-(sinx,cosx,) a. Calculate dp(x.y.z) b. Is total electric charge conserved? (Hint: Trick question.) ote: p(x,y,z) is the charge density dt
Help please Current Density and Drift Speed A group of charges, each with charge q, moves with velocity v^vector. The number of particles per unit volume is n. What is the current density J^vector of these charges, in magnitude and direction? Make sure that your answer has units of A/m^2. We want to calculate how long it takes an electron to get from a car battery to the starter motor after the ignition switch is turned. Assume that the current...
I need help with this please. 1. Calculate the volume of a 0.1M NaOH that 40.0 ml of the buffer could neutralize ( the pH of the buffer is 4.9) 2. Calculate the volume of a 0.1M HCl that 40.0 ml of the buffer could neutralize ( the pH of the buffer is 4.9) 3. How would your answers to 1 and 2 change if the system was made starting with 100.00ml of 0.010 M sodium acetate. The buffer is...
The density of water is given as 1 g/cm3. Determine the specific volume in ft3/lbm. I got 0.077 ft^3/lbm, and it's wrong, I can tell. I'm using the specific volume equation, sv = 1/rho, by the way. Can someone provide insight into this?
I'm given the density of cyclohexane as 0.799 g/Ml and I need help finding the volume from just that
