Answer:
Ohm's law
Explanation:
Ohm's law states that the potential difference across the ends of the conductor is directly proportional to the current passing through it.
∴V∝I
Answer and Explanation:
A null hypothesisstates that there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.
In order to reject or retain a null hypothesis, compare the P-value to the alpha . If the P-value is less than (or equal to) ,the null hypothesis is rejected in favor of the alternative hypothesis. If the P-value is greater than , the null hypothesis is not rejected.
The correct answer is B.
The electrons deal with most of the spectrum emissions. Whilst mass is technically a factor, the more precise answer would be B.
