Soil is a material composed of five ingredients — minerals, soil organic matter, living organisms, gas, and water. Soil minerals are divided into three size classes — clay, silt, and sand (Figure 1); the percentages of particles in these size classes is called soil texture.Soil contains air, water, and minerals as well as plant and animal matter, both living and dead. These soil components fall into two categories. ... Other, less common minerals include calcium, magnesium, and sulfur. The biotic and abiotic factors in the soil are what make up the soil's composition.

Friction
Explanation:
As the toy cars rolls away, more friction is created. The more friction there is, the more friction on surface rubs against another which creates friction which in-term slows it down. Hope this helps.

Share your thoughts about this statement by John Wesley
"Electricty is the soul of universe"
Answer:
I think this statement is true at least in modern day times. The world runs on nothing but technology. People use more technology instead of old school textbooks and papers. Imagine living in a world without technology… that means no cars, no trains, no devices, no machines like your stove or printer, no lights and lots more. John Wesley is 100 percent correct with this statement. Electricity is indeed the powerhouse of the universe.

How to find final velocity and initial velocity and acceleration ? :(
Explanation:
Final velocity=Initial velocity+(acceleration×time)
4 ways to find initial velocity:
1) Initial velocity=Final velocity-(acceleration×time)
2) Initial velocity=(Distance/Time)-((acceleration×time)/2)
3) Initial velocity=√Final velocity-(2×(acceleration×distance))
4) Initial velocity=2(distance/time)-Final velocity
Total force = Mass×Acceleration
(F=ma)
The change in the momentum of an object is represented by the following formula:
Impulse = (Force)(time) = change in momentum
I = F • t = pfinal – pinitial
A 1.0 kg rabbit traveling east at 10 m/s spots a predator, turns around, and then begins to travel west at 21 m/s.
What is the change in momentum of the rabbit, and what is another term for this concept?
The rabbits change of momentum is
A. 31 kg•m/s east
B. 31 kg•m/s west
C. 15.5 kg•m/s, west
D. 15.5 kg•m/s, east
This value can also be referred to as
E. Collisions
F. Potential energy
G. Kinetic energy
H. Impulse
Please help will mark brainliest
Hi there!
Recall that:
Change in momentum = mass × change in velocity
Or:
Δp = mΔv = m(vf - vi)
Plug in the given values. We can assign east to be positive and west to be negative in this instance (Velocity is a vector with direction).
Thus:
Δp = (1)(-21 - 10) = -31 kgm/s OR 31 kgm/s WEST.
The correct answer is B.
Change in momentum is EQUIVALENT to the quantity of IMPULSE.
The correct answer is H.

At any point along the track, the rollercoaster's mechanical energy is equal to the sum of its potential and kinetic energies,
M = P + K
and we assume the coaster's total mechanical energy is conserved throughout its motion along the track, so that M is the same at every point.
At the first point,
K + 75,000 J = 90,000 J ⇒ K = 15,000 J
At the second point, since M = 90,000 J everywhere,
K + 45,000 J = M ⇒ K = 45,000 J
At the third point,
K + 0 J = M ⇒ K = 90,000 J
The same principles apply to the pendulum, so M = 5,100 J throughout its swing.
At the first point,
K + 4,500 J = 5,100 J ⇒ K = 600 J
At the second point,
K + 0 J = M ⇒ K = 5,100 J
At the third point,
600 J + P = M ⇒ P = 4,500 J

During chemical reactions, bonds between atoms break and form. What does this mean in terms of subatomic particles? (1 point)
O Electrical fields of charged particles interact, bonding those with the same charge.
Electrical fields of neutral particles interact, bonding those with opposite charges.
O Electrical fields of neutral particles interact, bonding those with the same charge.
o Electrical fields of charged particles interact, bonding those with opposite charges
During chemical reactions, bonds between atoms break and form Electrical fields of charged particles interact, bonding those with opposite charges.
What is the chemical bonds?During chemical reactions, bonds between atoms break and form Electrical fields of charged particles interact, bonding those with opposite charges.
Since we know that every element have electrons in their atoms and every atom have vacant shells.
So during chemical reactions the elements fulfill their vacant shells and form bonds between each other it can be ionic or it can be covalent bond.
But when atoms breaks the bond their will be the positively or negatively charged electrons left in the atoms.
Hence During chemical reactions, bonds between atoms break and form Electrical fields of charged particles interact, bonding those with opposite charges.

Which shows the stars in the correct order, from smallest in size to largest?
white dwarf, Sun, red supergiant
Sun, red supergiant, white dwarf
white dwarf, red supergiant, Sun
Sun, white dwarf, red supergiant
Answer:
its A
Explanation:
White dwarf, Sun, red supergiant shows the stars in the correct order, from smallest in size to largest.
What is the size stars?More than 1.4 million kilometers span our Sun. However, not every star is the same size. They range in size from that of a metropolis to that of our solar system's half!
The mass of neutron stars is concentrated into a very compact area. Even though they are frequently only 20 to 40 km in diameter, they may hold the mass of one or two Suns. White dwarf stars are a little larger and frequently resemble the size of the Earth.
Compared to our Sun, the greatest supergiant stars can be more than 1500 times bigger. They are now more than 2,000 million kilometres across. Supergiants don't, however, have thousands of times the mass of the Sun. The reason for this is that as supergiants become older, their interiors become considerably more dispersed. Betelgeuse, a red giant in Orion's constellation, is nearly 1000 times broader than the Sun yet only has around 15 times as much mass.
