Atoms consist of protons, neutrons and electrons
Explanation:
There are three particles in an atom:
- Proton: it is located in the nucleus. Its mass is
, and it is positively charged (its electric charge is 
, also called fundamental charge) - Neutron: it is also located in the nucleus. Its mass is slightly larger than the proton (
), and it has no electric charge. Protons and neutrons are held together inside the nucleus by the strong nuclear interaction - Electron: it is located outside the nucleus, in a region called "electron cloud". According to quantum mechanics, its exact position cannot be determined, but it can only be described by a "wave function" which gives the probability of finding the electron at a certain position. Its mass is much smaller than the proton (
) and it is negatively charged (its charge is the opposite of that of the proton: 
).

Answer:
No
Explanation:
No matter where an object is, its mass will stay the same, but its weight might change depending on gravity.
There's multiple reasons a defense lawyer may admire Newtons 3rd Law but mainly it's because whenever for example someone is accused or did something there's a reason and also that person's going to have help.
According to Newton’s law of universal gravitation, as we move to higher altitudes, the force of gravity on us decreases and as we gain mass, the force of gravity on us increases both are the true statement.
<u>Explanation: </u>
Newton law of universal gravity extends gravity beyond the earth's surface. This gravity depends on the masses directly and inverse to the distance square between their centers.
Where,
F – Force, G – gravitational constant, M and m – masses in kg, r – distance in meters.
Since force is proportional to the masses of interacting objects. If the mass of any one object increases, gravity between them also gets increased. When moving to higher altitude, force decreases as the distance is inverse proportion to gravity.
Given :
A mover slides a refrigerator weighing 650 N at a constant velocity across the floor a distance of 8.1 m.
The force of friction between the refrigerator and the floor is 230 N.
To Find :
How much work has been performed by the mover on the refrigerator.
Solution :
Since, refrigerator is moving with constant velocity.
So, force applied by the mover is also 230 N ( equal to force of friction ).
Now, work done in order to move the refrigerator is :
Hence, this is the required solution.
