Answer: D, Refraction, Reflection, Refraction.
Explanation: Refraction is a rainbow. See image for info.
The potential difference comes out to be
Given:
σ = 8. 85 × 10-9 c/m2
we know,
given the potential difference between two equipotential surface=5v
E=∆v
∆d=∆v/E
Thus the potential difference is

Answer:
8 seconds
Explanation:
From Newton's second law;
Ft = m(v-u)
F = Force applied
t = time taken
v = final velocity
u = initial velocity
20 * t = 32 (9 - 4)
20t = 32 * 5
t = 32 * 5/ 20
t = 8 seconds
The answer would be:
B. Chlorine, iodine and Fluorine
Barium has 2 valence electrons. To satisfy the BaX₂ , this would mean that Barium will need to give one of each of its electrons. The elements that need 1 electron would be those that have 7 valence electrons to complete the octet. These elements would fall in group 7 or halogens. Chlorine, iodine and fluorine are all in Group 7, so this would be the best choice.
