I believe you're asking about Helium with two numbers to the left of it.
Once number is on top of the other.
The 4, which is on top, represents the atomic mass. Helium's atomic mass is 4.
The 2, which is on bottom, represents the number of protons (or atomic number). Helium's number of protons is 2.
Answer:
80.386 degrees
Explanation:
We use the cosine equation here (which is the adjacent side of the unknown angle divided by the hypotenuse
The adjacent side = 699ft
The hypotenuse = 1034ft
using cos∅ = Adjacent/hypotenuse
where ∅ is the unknown angle
cos ∅ = 699/1034 = 0.167
∅ = arccos 0.167 = 80.368°
As easy as one can imagine
Magnetic field can be generated when electric charge is in motion.
In short, Your Answer would be Option C
