Assume that the tap water to be analyzed contains a certain amount of an unknown cation which forms a complex with EDTA at pH 10 but not at pH 12. The formation constant for the EDTA complex of this unknown cation at pH 10 is 1×10^13. Neither the EBT nor Calcon indicators are affected by the...
In an inertia experiment using equipment very similar to the link below, I determined the following:
Trial with two 100 g masses near the ends of the rotating apparatus (larger moment arm):
- Final translational kinetic energy: 5.73 * 10^(-4) J
- Final rotational kinetic energy: 0.638 J...
This is what I've got so far in regards to the ballistic pendulum. I'm not sure if the last one is correct since the question specifically asks if the velocity will be larger or smaller. Also, if anyone can think of a better way to word anything or has any supporting evidence to add, I'd...
Law of Conservation of Energy:
1/2 m(v_1)^2 + mgh_1 + W_other = 1/2 m(v_2)^2 + mgh_2
So W_other would be the work done by the drag force. But how can I get any supporting evidence for my answers from that?
Well honestly, we've been taught nothing about the effects of air resistance. Up until now, we were told to assume that air resistance is negligible. Our currently teacher has been out sick for almost 2 weeks and the substitute barely teaches.
The best I can do is guess the answer from common...
The following link is a diagram of the motion of a pendulum I used in an experiment, where L represents the length of the pendulum arm:

Does drag cause the angle θ to be smaller or larger than it would be with no drag...
