The researcher can change one isotope into a different isotope of the same element by ADDING OR REMOVING NEUTRONS.
Isotopes refers to two or more forms of the same element, which have the same number of protons but different number of neutrons. The difference in the number of neutrons of a particular element is what brings about isotopes, thus, isotopes can be created by removing or adding neutrons to a particular element.<span />
Answer:
The larger resistance value is 144 ohms and the smaller resistance value is 48 ohms.
Explanation:
Given that Resistance, R, is inversely proportional to Power, the largest value of power will yield the smallest value of resistance and vice versa.
The largest value of resistance will be:
P = V²/R
R = V²/P
R = 120²/100
R = 144 ohms
The smallest value of resistance will be:
R = 120²/300
R = 48 ohms
Answer:
the answers should be B and D
Answer:
Explanation:
Given:
- the voltage of the source,
- distance of separation between the capacitor plates,
- energy of the capacitor,
Assuming that there is free space between the plates, so the permittivity, 
<u>We have the energy stored in a capacitor as:</u>
