Thx for your reply. I have figured out the answer as I realized that zinc was the limiting reagant.

Experiment equation: Zn(s) + 2HCL(aq) -> 2ZnCl(aq) + H2(g) a) If the the mass of zinc solid used was doubled, what effect would this have on temperature change? Answer: if mass of zinc increases, there will be an increase in zinc particles which increases the collisions between particles and...

I learned about Lenz's Law if that's what you mean. But I don't know about the vector Lorentz Force.

Here is the question. I just wanted to confirm and see if I'm understanding the question clearly. For 3a) I said the first wire would have the magnetic field going in a counter clock wise direction and the second wire would have a magnetic field going in a clockwise direction using the right...

Yes I see that. Thank you.

The ramp looks like this. (but the height isn't 2.5 m. It's 4m)

The wheels are attached to the cart and the mass is 5 kg. Sorry for the typo.

(mentor note: moved from Classical Physics forum hence no template) Hello, I am having trouble with this question: Imagine in real life there was a coefficient of kinetic friction of 0.4 between the plastic wheels of the cart and the wooden ramp. If there is only friction on the flat part of...
