Remember that like charges repel each other. That is, positive repels positive and negative repels negative. Similar to how the north poles of magnets repel each other and south poles repel. However, at the atomic scale, protons, which have positive charge, are more influenced by the "Strong Force," which binds them close together. If they were to be separated ever so slightly, then the electromagnetic force would take over and they would repel each other like you'd expect.
Neutrons are also held together via the Strong Force, but don't have a charge so when separated, don't have an electromagnetic force pushing them away from each other.
However, electrons act differently. There is no "Strong Force" just the electromagnetic force. So, they keep a great distance from each other.
So in an atom, protons and neutrons stay close to each other, taking up little volume, while electrons take up a lot of volume.
BTW, the reason why electrons and protons act differently when they are close together is because protons are made up of smaller particles the carry this Strong Force. For electrons, there is no smaller constituent. And therefore, all you have is the electromagnetic force to influence it. That's it.
Hope that helps.
Answer:
250 m
Explanation:
The car in this problem is moving of uniform accelerated motion, so we can use the following suvat equation:
where
s is the distance covered
u is the initial velocity
t is the time
a is the acceleration
Assuming the car starts from rest,
u = 0
Also we know that
a = 5 m/s^2 (acceleration of the car)
t = 10 s
Substituting, we find the distance covered:
The change of state as depicted by the model is condensation.
<h3>What is Condensation?</h3>
The process by which the water vapors get converted into liquid droplets to get settled on a cold surface is known as condensation.
As per the given problem, the cylinder in the left has the balls evenly spaced throughout and the right cylinder has the balls in the form of layers at its bottom.
So, this clearly reflects that the comparing both the balls in both cylinders, the right cylinder consists of the balls undergone through the process of condensation.
This is because,
During condensation, the vapor molecules get converted into liquid.
And in the left cylinder, the balls evenly spaced have more intermolecular distance which designates the gaseous molecules.
While in the right cylinder, the layered form of gas shows that the conversion occurred to some state of molecules, having less intermolecular space.
And liquid has less intermolecular space than gas.
Thus, we can conclude that the change of state as depicted by the model is condensation.

Answer:
The moment of inertia of the bar is 
Explanation:
Given that,
mass of bar = 150 g
Length l = 36 cm
We need to calculate the moment of inertia of the bar
Using formula of moment inertia
Where,
M = mass of the bar
L = length of the bar
Put the value into the formula
Hence, The moment of inertia of the bar is
Answer:
53,130 J
Explanation:
When a certain substance absorbs heat, the temperature of the substance increases according to the equation:
where
Q is the amount of heat absorbed
m is the mass of the substance
C the specific heat capacity
the change in temperature of the substance
In this problem:
m = 2.3 kg is the mass of copper
is the increase in temperature
is the specific heat of copper
So, the amount of heat absorbed is:
