The answer is protons. Neutrons have no charge and electrons have a negative charge so the positive charge must be protons.
We all know, Density = Mass/ volume.
When volume increases and the mass remains the same , the density will decrease considerably.
Answer:
its either A or C
Explanation:
i know B is not the answer
Answer:
V = 56.816 cm³
Explanation:
Given that,
The measured value of the cylinder is 54.5 cm³
The percent error in the measurement of the volume is 4.25%
We need to find the actual volume of the cylinder.
Firstly, we can find the error in the calculation as follows :
It is mentioned in the problem that, the teacher told her that she was 4.25% too high in her determination of the volume. It would mean that,
Total volume = 54.5 + 2.316 = 56.816 cm³
Hence, the actual volume of the cylinder is 56.816 cm³.
