I know something that a lot of people know but they get in trouble when they try to use it. I got it a long time ago from my old school buddy Ike Newton. I'll tell it to you, but you have to keep it to yourself, don't spread it around, and don't tell a lot of people where you got it.
Here it is:
<em>For every action, there is a reaction that is EQUAL and opposite. </em>
That means that if Jane pushes on the rock with 100 Newtons of force,
then <u><em>The rock pushes on Jane with 100 Newtons of force.</em></u>
It doesn't matter how much Jane's mass is, it doesn't matter what the mass of the rock is, and it doesn't even matter whether Jane is moving, or the rock is moving, or both of them are moving. If there's an action, then you can bet yer britches that there's a RE-action, and the RE-action is EQUAL and OPPOSITE to the action.
Why is this so hard ?
Answer:
The electric force is
Explanation:
From the question we are told that
The Bohr radius at ground state is
The values of the distance between the proton and an electron
The electric force is mathematically represented as
Where n and p are charges on a single electron and on a single proton which is mathematically represented as
and k is the coulomb's constant with a value
substituting values
Answer:
Explanation:
If we express all of the cordinates in their rectangular form we get:
A = (1404.77 , 655.06) m
Since we need C to be (0,0) we stablish that:
That way we make an equation system from both X and Y coordinates:
Replacing values:
With this system we can solve for both Db and Dc and get the answers to the question:
(a) The electrical resistance of the wire is determined as 9.27 x 10⁻⁴ ohms.
(b) The current flowing through the wire is 1.1 mA.
<h3>
Electrical resistance of the wire</h3>
The electrical resistance of the wire is determined as follows;
ρ = RA/l
RA = ρL
R = ρL/A
Where;
- A is area of the iron bar
- ρ is electrical resistivity = 1/conductivity = 1/1.0299 x 10⁷ = 9.7 x 10⁻⁸
A = πd²/4
A = π x (0.02)²/4
A = 3.14 x 10⁻⁴ m²
R = (9.7 x 10⁻⁸ x 3)/(3.14 x 10⁻⁴)
R = 9.27 x 10⁻⁴ ohms
<h3>From the chart, voltage after 120 minutes ≈ 1.1 V</h3>
Current, I = V/R
where;
I = 1.1/(1000)
I = 1.1 mA
