Choice-D is a simple statement of Newton's 2nd law of motion.
The equation for work (W) done by an electric field is:
W = qΔV
where q is the magnitude of the charge and ΔV is the potential difference. The question gives you W and q, so plug n' play to find ΔV:
10 = 2ΔV
ΔV = 5
Answer:
1) B
2) B
Explanation:
1) because the relative atomic mass of zinc is 29 and it has a valence electron of 2+ charge.
2) Oxygen because it is has the second highest electronegativity and has a valence electron of-2 charge.
Hi. Below I attached pictures of both penguin, and I'd suggest you to search about each and compare.
