(30, 5)
(10, 1)
change of y / change of x
= (30 - 10) / (5 - 1)
= 20 /4
= 5
Answer:
is the no. of electrons
Explanation:
Given:
- quantity of charge transferred,
<u>No. of electrons in the given amount of charge:</u>
As we have charge on one electron 
so,
is the no. of electrons
- Now if each water molecules donates one electron:
Then we require 
molecules.
<u>Now the no. of moles in this many molecules:</u>
where
Avogadro No.
- We have molecular mass of water as M=18 g/mol.
<u>So, the mass of water in the obtained moles:</u>
where:
m = mass in gram
This question is incomplete, the complete question is;
A parallel-plate capacitor is made from two aluminum-foil sheets, each 3.0 cm wide and 5.00 m long. Between the sheets is a mica strip of the same width and length that is 0.0225 mm thick. What is the maximum charge?
(The dielectric constant of mica is 5.4, and its dielectric strength is 1.00×10⁸ V/m)
Answer: the maximum charge q is 716.85 μF
Explanation:
Given data;
with = 3.0 cm = 0.03
breathe = 5.0 m
Area = 0.03 × 5 = 0.15 m²
dielectric strength E = 1.00 × 10⁸
∈₀ = 8.85 × 10⁻¹²
constant K = 5.4
maximum charge = ?
the capacitor C = KA∈₀ / d
q = cv so c = q/v
now
q/v = KA∈₀ / d
q = vKA∈₀/d = EKA∈₀
we substitute
q = (1.00 × 10⁸) × 5.4 × 0.15 × 8.85 × 10⁻¹²
q = 716.85 × 10⁻⁶ F
q = 716.85 μF
the maximum charge q is 716.85 μF
Answer:
6m/s squared
Explanation:
We'll use a simple kinematic equation to solve this.
v=v⊕at
