yes, you need oxygen but that should not be a problem according to articles. The reactions you listed are correct.

Well, hopefully we should have glucose oxidase getting reduced (glucose oxidised). The point of the voltammetry is switching between ferri/ferrocyanide redox couples. Ferricyanide should hopefully work as a mediator (getting reduced to ferrocyanide) transport electrons to electrode and get...

Hey, this is not a homework question really but more a research issue my fellow students and I have run into. So basically, we have a project where we have cross-linked glucose oxidase to a polypyrrole surface on a gold electrode. The solution additionally contain PBS as well as ferricyanide...

ah, sry, stupid me, i can use the formulas for x and y and use substituion and find the initial velocity and angle and then use the formulas for vx and vy to find the velocity when it hits the ground, I am going to calculate.

are you sure that would work when the initial velocity and the angle are unknown. won't that give two variables?

I have the x and y coordinates for when the ball is at its top height after each bounce also the coordinates at the point it is throw also the coordinates when it hits the ground. At the beginning of the video when the ball is thrown at an angle I guess is about -30 degrees. Also there is a...

the problem is that its not thrown from a 0 degree angle. I don't know the initial speed it is thrown with, almost nothing.

ok, does anybody have any other suggestions to solve this. I do not think I have the possibility of calculating the velocity of the ball when it hits the ground.

this was what I feared, all of my classmates are having problems with this assignment, oour teacher is away and no other physics teacher at my school can tell us how to do this. I am going to calculate this and post my results if I am uncertain.

Hello, I am having a problem calculating the angular velocity of a bouncing ball. At first this ball is thrown a distance and then hits the ground. Before it hits the ground it has no angular velocity. After it hits the ground it gets an angular velocity. I have the inertia of the ball...

Homework Statement ok, I am doing an assignment on torricellis law but I have run into a big problem. I have a bowl which can be described by the function: squareroot(1/0.11*h). This bowl has a hole in the bottom of a radius of 0.004m. But when I use the relavant formula and integrate it...

Homework Statement Hey, I am doing some work with torricellis equation and I have some questions. I am using the equation: dH/dt*A(h)=-B*squareroot(2*g*h) My question is, in my textbook it says the general formula is: dH/dt*A(h)=-0.6*B*squareroot(2*g*h) I want to know where the...
