If
Sunny watched a video of her professor’s lecture on genes and environment the
night before class and her professor facilitated a discussion about the role of
nature and nurture with respect to development, Sunny is experiencing being
advanced in their lesson. Nurture plays an important part in this. The
environment poses an encouraging and stimulating atmosphere where Sunny might
enjoy learning about things.
<span>In general, as you move across a row in the periodic table, B. atomic radius decreases.
This is because there is a stronger attraction between outermost electrons and nucleus, which is why the radius between them becomes smaller.

Answer:
Joule
Explanation:
energy, work, quantity of heat
m2·kg·s-2
Answer: 2.5 m/s and 6.25 m
Explanation:
u = 0
a = 0.5 m/s²
t = 5 s
v = u + at
= 0 + 0.5 × 5
= <u>2.5 m/s</u>
s = ut + 1/2 at²
= 1/2 × 2.5 × 5
=<u> 6.25 m</u>
Answer:
(A) 667.5 N/m
(B)
Explanation:
(A) Let the spring constant be k.
Using the formula F = kx
k = 251 / 0.376
K = 667.5 N/m
(B)
Work done
W = 0.5 × kx^2
W = 0.5 × 667.5 × 0.376 × 0.376
W = 47.2 J
