Answer:
Explanation:
The difference between the water level in the eudiometer tube and the water level in the beaker must be measured because we have to put into consideration, the pressure of the gases in the eudiometer tube. This said pressure of gas in the eudiometer must equal the atmospheric pressure. If or by chance, the water levels happens not to be at the same height, then this is not the case. And then, as a result, in order to account for the difference between both, while also being able to get accurate results, you have to find the difference or subtract the water levels and then go ahead in converting them to mmHg.
Answer:
The speed of the object at the lowest point in its trajectory is:
Explanation:
We can use the conservation of energy between the maximum point of swing and the lowest point of the pendulum.
(1)
Where:
- h is the height of the object at 30° with the vertical.
- v is the speed at the lowest point.
We can find h using trigonometry.
Now, using equation (1) we can find v.
