Answer:
Both statements I, and II are true
Explanation:
I)One is true.The number of protons of the element is the defining characteristic of it. This is, if we take a proton or add a proton to a nucleus we will be changing the element. Therefore, the number of protons is the same for all neutral and not neutral atoms of that element.
II)Two is true. If an atom is neutral, it will have the same number of electrons and protons. As the number of protons for an element cannot change (see I), then the number of electrons will be the same for all neutral atoms of this element.
III)Three is false. We can have a neutral atoms of the same element with different number of neutrons, as neutrons do not change the charge of the atom(they change their mass, though). These are called Isotopes.

The answer would be:
Pulling a trailer up a hill
Here is why:
In physics, work is computed by the formula:
W = Fd or F(cosΘ)d
Where: F = Force applied on the object
d =displacement
So in order for work to be done, the object needs to be displaced. In the case of the trailer, the trailer is being pulled and it is travelling in the direction of the force applied.
The other options the object is not displaced. Even if you exert a force, if the displacement remains the same, then it will always be zero, so the force times displacement will be 0, hence no work is done.
Answer:
A
Explanation:
Laddering can also be used as an overall retirement planning approach for all retirement investments. The idea is to separate CDs, cash, bonds, annuities, and others into different "ladders" (or "buckets" or "baskets") depending on when the asset is expected to be liquidated to fund the retirement revenue stream.
