Answer:
A. Hund's rule has been violated
Explanation:
There must be one electron with the same spin in each orbital of the same energy before you can put two in the same orbital. In the photo, the 2s sublevel is completely filled before the 1s sublevel (if anything the 1s should have an up spin and down spin, with the 2s having one up spin).
Answer:
"The higher the spring constant, the stiffer the spring. The spring constant is not the same value for different elastic objects. For a given spring and other elastic objects, the extension is directly proportional to the force applied. For example, if the force is doubled, the extension doubles."

Ok what’s the question sir
