Explanation:
An ocean is an example of a wave form
:<span> </span><span>Under the assumption that a cell is made up of two concentric spheres you find the surface are of the inside sphere which will be your A.
You already have your separation and dielectric constant so just use the formula you stated towards the end of your question and you get 8.93x10^-11 Farads which is about 89pF</span>
Answer:
r2 = 2.401557 cm
distance = 0.10 cm
Explanation:
given data
radius = 2.50 cm
density = 15.0 nC/m
voltmeter read = 175
solution
we know here potential difference that is express as
ΔV = 
...........1
so here
as here 
is linear charge density
r2 = r1 × 
r2 = 2.40 × 
r2 = 2.401557 cm
and
here distance above surface will be
distance = r1 - r2
distance = 2.50 - 2.40
distance = 0.10 cm
Answer:
Explanation:
electric field between plates
= surface charge density / ε₀
= 108 x 10⁻¹² / 8.85 x 10⁻¹² (ε₀ = 8.85 x 10⁻¹² )
= 12.20 V/ m
Electric potential diff
= electric field x distance between plates
= 12.20 x 17 x 10⁻³ V
= 0.207 Volt
