energy associate with position or shape
Answer:
Explanation:
Before the Rutherford's model of the atom, the plum pudding model proposed by J.J Thomson through his experiment using the gas discharge tube was the prevalent structure of the atom known.
Through Thomson, it was widely and popularly believed that the atom is made up of a pool of negatively charged particles.
When Rutherford performed the Alpha scattering experiment using a thing gold foil, he observed that all the alpha particles passed through the thin gold foil and just a few of them were deflected back.
To explain this, the suggested the atomic or nuclear model of that atom in which an atom has a small positively charged center called nucleus where all the mass is concentrated.
Today, the suggestion that an atom is made up of nucleus is highly relevant and still consistent.
The main difference between series and parallel circuits is that, in series circuits, all components are connected in series so that they all share the same current whereas. In parallel circuits, components are connected in parallel so that they all have the same potential difference between them
A charged particle has an electrostatic field surrounding it.
When the particle is in motion, the moving charge is an
electric current, and that has a magnetic field around it.
Answer:
I₂ = 8 mG
Explanation:
The intensity of a beam is
I = P / A
Where P is the emitted power which is 3) 3
Let's use index 1 for the initial position of r₁ = 6 ft and 2 for the second position r₂ = 3 ft
I₁ A₁ = I₂ A₂
I₂ = I₁ A₁ / A₂
The area of the beam if we assume that it is distributed either in the form of a sphere is
A₁ = 4π r²
We substitute
I₂ = I₁ (r₁ / r₂)²
I₂ = 2 (6/3)²
I₂ = 2 4
I₂ = 8 mG
