The list that places different units of matter in the correct sequence from largest to smallest is as follows:
The human body, organs, molecules, atoms neutrons.What is the matter?Matter may be defined as a type of substance that possesses a specific mass and occupies space by having a specific volume. So, it certainly has both mass and volume. In nature, each and every object is made up of matter.
With respect to the question, the human body is the largest unit that consists of matter. The body of a human generally consists of numerous organ systems which are built through the collection of other different organs.
The organ is further made up of the collection of tissues that are formed by the collection of cells. Cells possess numerous molecules which are made of atoms. Atoms have three types of subatomic particles, i.e. electrons, protons, and neutrons.
Therefore, the list that places different units of matter in the correct sequence from largest to smallest is well mentioned above.

A girl throws a pebble into a deep well at 4.0 m/s (downward). It hits the water in 2.0 s. How far below the ground is the water's surface? What is the pebble's average velocity?
Answer:
27.6 m13.8 m/sExplanation:
(b) The initial velocity is added to that due to acceleration by gravity. The velocity is increased linearly by gravity at the rate of 9.8 m/s². The average velocity of the pebble will be its velocity halfway through the 2-second time period.* That is, it will be ...
4 m/s + (9.8 m/s²)(2 s)/2 = 13.8 m/s . . . . average velocity
__
(a) The distance covered in 2 seconds at an average velocity of 13.8 m/s is ...
d = vt
d = (13.8 m/s)(2 s) = 27.6 m
The water is about 27.6 m below ground.
_____
* We have chosen to make use of the fact that the velocity curve is linear, so the average velocity is half the sum of initial and final velocities:
vAvg = (vInit + vFinal)/2 = (vInit + (vInit +at))/2 = vInit +at/2
__
If you work this in a straightforward way, you would find distance as the integral of velocity, then find average velocity from the distance and time.
[tex]\displaystyle d=\int_0^t{(v_0+at)}\,dt=v_0t+\dfrac{1}{2}at^2=t\left(v_0+a\dfrac{t}{2}\right)\\\\v_{avg}=\dfrac{d}{t}=v_0+a\dfrac{t}{2}\qquad\text{the formula we started with}[/tex]
A 10-kg wagon is pulled by a force of 70 Newtons while friction provides 20 Newtons of force. How much acceleration will the wagon have?
Answer:
5m/s²
Explanation:
Given parameters:
Mass of wagon = 10kg
Force of pull = 70N
Frictional force = 20N
Unknown:
Acceleration of the wagon = ?
Solution:
Frictional force is a force that opposes motion.
The net force is given as:
Net force = mass x acceleration
Force of pull - Frictional force = mass x acceleration
Insert the parameters and solve;
70 - 20 = 10 x acceleration
50 = 10 x acceleration
Acceleration = 5m/s²

Jill is pulling a 200. Newton sled through the snow at constant velocity using a horizontal force of 10. Newtons. What is the kinetic coefficient of friction of the sled on the snow?
Answer:
The kinetic coefficient of friction of the sled on the snow is 0.05
Explanation:
The given parameters are;
The weight of the sled Jill is pulling, W = 200 N
The force with which Jill is pulling the the sled = 10 Newtons
The nature of the speed with which the sled is pulled = Constant speed
Therefore, given that the only opposing force to the pulling of the sled = The force of kinetic friction, we have;
The force with which Jill is pulling the the sled = 10 Newtons = The force of kinetic friction, [tex]F_k[/tex]
The force of kinetic friction = The weight of the sled, W × The kinetic coefficient of friction of the sled on the snow, [tex]\mu _k[/tex]
[tex]F_k[/tex] = W × [tex]\mu _k[/tex]
[tex]\mu _k[/tex] = [tex]F_k[/tex]/W = 10 N/(200 N) = 0.05
The kinetic coefficient of friction of the sled on the snow = [tex]\mu _k[/tex] = 0.05.

If Juan upgrades from a sports car to a large truck, what will happen to the
force needed to keep the truck going at the same speed? Use this
sentence frame:
Answer:
The force must increase
Explanation:
According to newton's second law "force is the product of mass and acceleration".
Force = mass x acceleration
Now, the mass of the sports car is lesser compared to that of the truck. Therefore, to take both automobiles to the same speed, enough force must be applied by the engine of the truck.
There must be an increase in the force in order to make both automobiles attain the same speed.

The charge of a capacitor is 1500μC. Determine the potential difference between the plates if their capacitance is 5μF.
Answer:
The potential difference between the plates of the capacitor is 300V
Explanation:
Given;
capacitance of the capacitor, C = 5μF = 5 x 10⁻⁶ F
charge of the capacitor, Q = 1500μC = 1500 x 10⁻⁶ C
The potential difference between the plates of the capacitor is given by;
V = Q / C
Where;
V is the potential difference between the plates
Q is the charge of the capacitor
C is the capacitance
[tex]V = \frac{Q}{C} \\\\V = \frac{1500*10^{-6}}{5*10^{-6}} \\\\V = 300 \ volts[/tex]
Therefore, the potential difference between the plates of the capacitor is 300V

(ch) 1.43 s
Explanation:
Vertical Launch Upwards
In a vertical launch upwards, an object is launched vertically up without taking into consideration any kind of friction with the air.
If vo is the initial speed and g is the acceleration of gravity, the maximum height reached by the object is given by:
[tex]\displaystyle h_m=\frac{v_o^2}{2g}[/tex]
Similarly, the time it needs to reach the maximum height is:
[tex]\displaystyle t_m=\frac{v_o}{g}[/tex]
The object's speed (vf) after time t is:
[tex]v_f=v_o-g.t[/tex]
The baseball is thrown up at vo=30 m/s.
(a) It's required to calculate the time it needs to reach the maximum height:
[tex]\displaystyle t_m=\frac{30}{9.8}=3.06[/tex]
[tex]t_m=3.06~s[/tex]
(b) The maximum height is:
[tex]\displaystyle h_m=\frac{30^2}{2(9.8)}=45.92[/tex]
[tex]h_m=45.92~m[/tex]
(c) The time needed to travel up is the same time required to return to the starting point:
[tex]t_f=2*t_m=2*3.06[/tex]
[tex]t_f=6.12~s[/tex]
(ch) The speed will be vf=16 m/s at a certain time. Using the equation
[tex]v_f=v_o-g.t[/tex]
We solve for t:
[tex]\displaystyle t=\frac{v_f-v_o}{g}[/tex]
[tex]\displaystyle t=\frac{30-16}{9.8}[/tex]
t = 1.43 s

Find the force of gravity between a cubic meter of water (1000kg) and the Sun. The Sun's mass is 1.99 x10^30 kg and is 1.50 x10^11 m away.
A) 17.0 N
B) 5.90 N
C) 2.0 N
D) 47.20 N
Answer:
F = 5.9 N
Explanation:
Given that,
Mass of water, m₁ = 1000 kg
Mass of the Sun, [tex]m_2=1.99\times 10^{30}\ kg[/tex]
Distance between two bodies, [tex]r=1.5\times 10^{11}\ m[/tex]
We need to find the force of gravity between water and the Sun. The formula for the gravitational force between two bodies is given by :
[tex]F=G\dfrac{m_1m_2}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{1000\times 1.99\times 10^{30}}{(1.5\times 10^{11})^2}\\\\F=5.89\ N[/tex]
or
F = 5.9 N
