Let's describe them from smallest to largest. In fact the size order is not exact as there are exceptions.
An asteroid is a rocky body which lies in the asteroid belt between Mars and Jupiter. They are typically quite small object. The largest asteroid Ceres has been reclassified as a dwarf planet.
A moon is typically a rocky body which is in orbit around a planet. Some moons such as our Moon are quite large and are typically bigger than asteroid. Some moons can actually be smaller than some asteroids.
A planet is a nearly spherical body which is in orbit around the Sun. Planets are larger than moons.
A star is what planets orbit around. It is the source of light and heat. Our Sun is a star which is many times bigger than all of the planets.
A solar system is a star and all of its planets, asteroids, comets and other bodies. It is significantly bigger than a star.
A galaxy, such as our Milky Way Galaxy, is a collection of solar systems orbiting around a central core. Most galaxies have a supermassive black hole at their centres.
Galaxies also form clusters which are large scale structures.
The universe is everything. It contains billions of galaxies.

Why do the planets orbit the Sun in an elliptical shape?
Answer:
That's essentially how objects in orbits work as they move closer to the body they orbit, they accelerate faster and faster. Our penny will get so fast that, once it comes around the planet, it will be flung very far away, which will then slow it down. This is what creates an elliptical orbit.

A defibrillator is used during a heart attack to restore the heart to its normal beating pattern. A defibrillator passes 18 A of current: through the torso of person in 2.0 ms- (a) How much charge moves during this time
Answer:
q = 0.036 C
Explanation:
Given that,
Current passes through a defibrillator, I = 18 A
Time, t = 2 ms
We need to find the charge moved during this time. We know that,
Electric current = charge/time
[tex]q=It[/tex]
Put all the values,
[tex]q=18\times 0.002\\\\q=0.036\ C[/tex]
So, 0.036 C of charge moves during this time.

Can you tell from an FBD if an object is moving or not? Explain your response.
Answer:
Yes it is possible to tell if an object is moving or not using a FBD based on Newton's Laws of Motion
Explanation:
A Free Body Diagram is the representation of an object in a diagram that shows (all) the vector of the forces that act on the object
When the sum of all the force vectors acting on the body give a resultant force the object will move in the direction of the force according to Newton's First Law of motion, which states that an object will continue in its rest state or continue its uniform motion on a straight path unless a force acts on the object
The net force, 'F', can be represented according to Newton's Second Law of motion which is F = m·a, where 'a' represents the acceleration (rate of change in velocity) of the object as the object begins to move from rest
Therefore;
From a FBD it is possible to tell if an object is moving or not.

You have a grindstone (a disk) that is 98.0 kg, has a 0.335-m radius, and is turning at 100 rpm, and you press a steel axe against it with a radial force of 23.6 N. Assuming the kinetic coefficient of friction between steel and stone is 0.192, calculate the angular acceleration of the grindstone.
Answer:
[tex]a=0.276[/tex]
Explanation:
From the question we are told that:
Mass [tex]m=98.kg[/tex]
Radius [tex]r=0.335[/tex]
Angular velocity [tex]\omega=100rpm[/tex]
Radial force of [tex]F_r=23.6 N.[/tex]
Kinetic coefficient of friction [tex]\mu=0.192[/tex]
Generally the equation for Kinetic Force is mathematically given by
[tex]F_k=\mu.F_r[/tex]
[tex]F_k=0.192*23.6[/tex]
[tex]F_k=4.5312[/tex]
Generally the equation for Torque on Center is mathematically given by
[tex]Ia=f_k*r[/tex]
Where
[tex]I=\frac{Mr^2}{2}[/tex]
Therefore
[tex]a=\frac{2f_k}{Mr}[/tex]
[tex]a=\frac{2*4.5312}{98*0.335}[/tex]
[tex]a=0.276[/tex]
Therefore Angular acceleration of the grindstone is
[tex]a=0.276[/tex]

D. The higher temperature decreases the reaction rate, but it also
favors the forward reaction.
Answer: B
Explanation: The higher temperature increases the reaction rate but also favors the reverse read on.
The higher temperature increases the reaction rate, but it also favors the reverse read on. So, option B.
What is meant by rate of a reaction ?The pace at which the products are created from the reactants in a chemical reaction is referred to as the rate of reaction.
Here,
Generally, reactions progress more quickly as the temperature rises.
The average kinetic energy of the reactant molecules will rise with a rise in temperature. The number of molecules having threshold energy rises, increasing the quantity of efficient collisions that actually occur.
Therefore, as the temperature of the reaction is increased, the rate of the reaction increases. But also favors the reverse reaction.
Hence,
The higher temperature increases the reaction rate, but it also favors the reverse read on.

If V is the original volume, V' is the new volume, T is the original Kelvin temperature, and T' is the new Kelvin temperature, how is Charles's law expressed mathematically
Answer:
[tex] \frac{V}{T} = \frac{V'}{T'}[/tex]
Explanation:
Given the following data;
Original volume = V
New volume = V'
Original temperature = T
New temperature = T'
To write an expression for Charles's law;
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles law is given by the formula;
[tex] \frac {V}{T} = K[/tex]
[tex] \frac{V}{T} = \frac{V'}{T'}[/tex]

4. A car accelerates at 2.5 m/s^2, covers 4 km in 0.8 min. How fast was it moving at the beginning
of the time interval? *
Answer:
Initial velocity, u = 23.33 m/s
Explanation:
Given the following data;
Acceleration = 2.5 m/s²
Distance = 4 km to meters = 4000 meters
Time = 0.8 mins to seconds = 0.8 * 60 = 48 seconds.
To find the initial velocity, we would use the second equation of motion;
[tex] S = ut + \frac {1}{2}at^{2}[/tex]
Where;
S represents the displacement or height measured in meters.
u represents the initial velocity measured in meters per seconds.
t represents the time measured in seconds.
a represents acceleration measured in meters per seconds square.
Substituting into the equation, we have;
4000 = u*48 + ½*2.5*48²
4000 = 48u + 1.25*2304
4000 = 48u + 2880
48u = 4000 - 2880
48u = 1120
Initial velocity, u = 1120/48
Initial velocity, u = 23.33 m/s
An object rolls east at a steady speed of 12 m/s for 3.0 seconds. What distance did it travel?
O A. 36 m
o B. 24 m
O C. 18 m
O D. 7.0 m
Answer:
[tex]\boxed {\boxed {\sf A. \ 36 \ m}}[/tex]
Explanation:
The distance an object travels is the product of its speed and time.
[tex]d=s \times t[/tex]
The object's speed is 12 meters per second and the time is 3 seconds.
s= 12 m/s t= 3 sSubstitute the values into the formula.
[tex]d= 12 \ m/s \times 3 \ s[/tex]
Multiply. Note that the units of seconds will cancel, so we are left with meters as our units.
[tex]d= 12 \ m * 3[/tex]
[tex]d= 36 \ m[/tex]
The object travels a distance of 36 meters and choice A is correct.
