Answer:
Sodium Na and Magnesium Mg
Explanation:
In the period table, you can see that Sodium (group 1) has 11 protons, and Magnesium (group 2) has 12 protons. 11+12=23 protons
I think it is d. I think but I don't know for a fact.
Answer:
Explanation:
The density of the magnetic flux is given by the following formula:
The normal vector A and the vector of the magnitude of the magnetic field are perpendicular, then, the angle is zero:
The magnitude of the magnetic field is calculated by using the formula for B at a distance of x to a point in the plane of the loop:
For x = 0 you have:
R is the radius of the circular loop and its values is:
Then, you replace in the equation for B with mu_o = 4\pi*10^-7 T/A:
and the density of the magnetic flux is
The answer is 34 good luck stay safe
It will be cloudy and there will be rain.
Hope this helps
