The correct option is A.
J.J Thompson proposed the plum model of atomic structure. The model states that the atom is a sphere of positively charged matter in which electrons are embedded.
Rutherford designed an experiment to verify the truth of this model. He set up a beam of alpha particles which are to be passed a thin gold foil. If the JJ model of atomic structure is correct, all of the alpha particles suppose to pass through the foil, but some of the alpha particles bounced back while those that passed through the foil emerged at different angles.
It should be chestnut hair.
All boxes should be Ee which is dominant.
We know that force <span>for a linear spring is equal to F=kx. Since energy is the potential to do work, and the spring is assumed to be perfectly elastic. Work can be written as:
W = F (integral sign) d</span>x
Therefore,
<span>W=k(Δx<span>)^2 / 2
W = F </span></span>Δx / 2
<span>W = 120 (2.0) / 2
W = 120

Well first we can tell that it will be very cold. For ex. Earth is fairly close to the sun. It gets pretty hot whenever the sun is out. Therefore we know being closer to the sun creates warmth on the planet. And as you can see on the picture of the solar system I attached, it seems as if the planet gets bigger the further away from the sun. So I would appose cold and big. <span />
