The answer should be D) electrical
they will both do the exact same thing, as long as they are bothh identical
Answer:
Temperature gradient = 30
90F - 60F = 30F
The temperature gradient is 30F.
If I am right, let me know.
Tin-120 because an atom has to have a neutral charge. If an atom has 50 electrons it must have 50 protons unless it's an ion. Add 70 to the atomic mass because it has 70 neutrons on top of 50 protons. That equals to 120. Tin has an atomic number of 50 (meaning it has 50 protons) and it has roughly an atomic mass of about 118. If the given has 70 neutrons then it's a isotope of tin.
