The wire vibrates back and forth between the poles of the magnet.
The frequency of the vibration is the frequency of the AC supply.
“a point representing the mean position of the matter in a body or system.”
We will first record its mass and then its volume by measuring its dimensions
then divide mass by volume and will get density of regular solid
Explanation:
This problem seeks to ensure that the student comprehends the meaning of precision and accuracy.
These two key terms are used to express how reliable experimental values obtained are.
- Precision is the ability to consistently reproduce a result.
- Accuracy is the nearness of the measure value to the true value.
- The different between the measured and true values gives the error in the result.
In the problem given, the most accurate reading would be one that has value close to the standard mass of 150g. Any student that reports this value would be reported as accurate.
The precise reading would be for the student that is able to repeatedly produce the same kind of values. This is irrespective of whether the values are close to the true value or not.

Since there is constant pressure, you can use Charles's Law:
V1/T1 = V2/T2
10L/280K = 20L/T
0.0357 = 20/ T
T = 20/0.0357
T = 560K which is the new temperature
