I think the answer may be D- mechanical
Density = mass divided by volume so if you use that formula Liquid A turns out to be a higher density so it flows slower.
Answer:
a)v= 675V
b) v=-675V
c)v=-450V
Explanation:
Formula: V = k*sum(qi/ri)
Given:
q1 = +6.00nC --> R1 = 2.00cm
q2 = -9.00nC --> R2 = 4.00cm
(a) r = 0. So, inside both shells
V=675V
(b) r = 4.00cm. So, This point is outside of shell 1 but inside shell 2.
V=-675V
(c) r = 6.00cm. So, This point out of both shells.
Answer:
b because we apply Hooke's law
Explanation:
Hooke's law
