Pretty sure it's C - The Earth is rotating from East to West. It's the only answer that really makes sense.
For the first question, make a question that is quantifiable
or can be counted. This can be anything, as long as its quantifiable, like "How many species of trees are in this certain area?" While for the second it can be a question that can is more
qualitative and are more open-ended questions, example, “What are the
contaminants present in this water sample”
Answer:
Explanation:
From the given information:
We know that the thin spherical shell is on a uniform surface which implies that both the inside and outside the charge of the sphere are equal, Then
The volume charge distribution relates to the radial direction at r = R
∴
To find the constant k, we examine the total charge Q which is:
∴
Thus;
Hence, from equation (1), if k =
To verify the units:
↓ ↓ ↓
c/m³ c/m³ × 1/m
Thus, the units are verified.
The integrated charge Q
since
Answer:
Number of Protons and Electrons: 80
Number of Neutrons: 121
