Which of the following methods of soil conservation uses the roots of plants as anchors in the soil? (5points)
Group of answer choices
Adding fertilizers to soil
Planting trees on sloped surfaces
Adding beneficial organisms to soil
Watering grasses to add moisture
Answers
Answer:
Planting of trees on sloped surfaces is a method of conservation that utilizes the roots of plants. Planting trees on such areas would prevent hazards and maintain the soil formation future since the roots would hold the soil together preventing or minimizing any soil erosion.

A day-care center has a merry-go-round that consists of a uniform 240-kg circular wooden platform 4.00m in diameter. Four children run alongside the merry-go-round and push tangentially along the platform’s circumference until, starting from rest, the merry-go-round is spinning at a rate of 2.14 rev/minute. During the spin-up:
a) If each child exerts a sustained force of 26N, how far does each child run?
b) What is the angular acceleration of the merry-go-round?
SHOW ALL WORK AND STEPS PLEASE.
Answers
Answer:
a) The distance each child ran is approximately 0.232 m
b) The angular acceleration is 0.21[tex]\overline 6[/tex] rad/s²
Explanation:
The given parameters of the merry-go-round are;
The mass of the merry-go-round, m = 240-kg
The diameter of the merry-go-round, d = 4.00 m
The number of children pushing tangentially on the merry-go round = Four children
The spinning rate of the merry-go-round, n = 2.14 rev/minute
a) Given that the force exerted by each child = 26 N, we have;
The total force applied by the four children, F = 26 N × 4 = 104 N
The tangential acceleration, [tex]a_t[/tex] = F/m = 104 N/240-kg = 0.4[tex]\overline 3[/tex] m/s²
The angular acceleration, α = [tex]a_t[/tex]/r
Where, the radius of the merry-go-round, r = d/2
∴ r = 4.00 m/2 = 2.00 m
α = 0.4[tex]\overline 3[/tex] m/s²/(2.00 m) = 0.21[tex]\overline 6[/tex] rad/s²
We have;
ω² = ω₀² + 2·α·Δθ
The merry-go-round starts from rest, therefore; ω₀ = 0 rad/s
ω² = 2·α·Δθ
Δθ = ω²/(2·α)
n = 2.14 rev/minute
∴ ω = 2·π×2.14/60 rad/s ≈ 0.22410 rad/s
∴ Δθ = (0.22410 rad/s)²/(2 × 0.21[tex]\overline 6[/tex] rad/s²) ≈ 0.11589 rad
Therefore, the angle each child ran, θ = 0.11589 rad
The distance each child ran = r·θ
∴ The distance each child ran = 2.00 m × 0.11589 rad ≈ 0.232 m
b) From part 'a' above, the tangential acceleration, [tex]a_t[/tex] = 0.4[tex]\overline 3[/tex] m/s²
Angular acceleration, α = [tex]a_t[/tex]/r
∴ α = 0.4[tex]\overline 3[/tex] m/s²/(2.00 m) = 0.21[tex]\overline 6[/tex] rad/s²
The angular acceleration = 0.21[tex]\overline 6[/tex] rad/s²

Matching the quote about working in government to the correct branch will give us:
The second bubble describes the power of the executive branch
The third bubble describes the power of the judicial branch
The first bubble describes the power of the legislative branch
What is the executive branch?The power of the Executive Branch is vested in the President of the United States, who also acts as head of state and Commander-in-Chief of the armed forces.
The executive branch or is the part of government that enforces law, and has responsibility for the governance of a state.
In political systems based on the principle of separation of powers, authority is distributed among several branches (executive, legislative, judicial)—an attempt to prevent the concentration of power in the hands of a single group of people.
The executive enforces the law as written by the legislature and interpreted by the judiciary.
The executive can be the source of certain types of law, such as a decree or executive order. Executive bureaucracies are commonly the source of regulations.
What is the judicial branch?The third branch of government is the Judicial branch. The Judiciary is made up of courts -- Supreme, Circuit, the magistrate (local) and municipal (city) courts. The Judicial branch interprets the laws.
The state judges are elected by the citizens rather than being appointed. They also run for their office as members of a political party.
The judiciary is the system of courts that interprets, defends, and applies the law in the name of the state. The judiciary can also be thought of as the mechanism for the resolution of disputes.
In many jurisdictions, the judicial branch has the power to change laws through the process of judicial review.

If energy is conserved, then:
O A. initial (PE + KE) = final (PE + KE).
O B. the initial KE must be zero.
O C. the momentum does not change.
O D. PE(before) = KE(before).
Answers
If energy is conserved, then initial (PE + KE) = final (PE + KE). So, the correct option is A.
What is meant by Law of Conservation of Energy ?The law of conservation of energy states that, energy can neither be created nor be destroyed, but can be transformed from one form to another.
Here,
According to law of conservation of energy,
The total energy of an isolated system remains constant. That means, the total energy of the system in the initial state will be same as that in the final state.
The total mechanical energy is the sum of kinetic energy and potential energy.
TE = KE + PE
Therefore, the energy to be conserved in the system,
Initial TE = Final TE
So, Initial (KE + PE) = Final (KE + PE)
Hence,
If energy is conserved, then initial (PE + KE) = final (PE + KE).

Answers
Σf = m v^2 / r
Σf = 52 8^2 / 1.6
Σf = 2080 N
Given values are:
Mass, m = 52 kgVelocity, v = 8.0 m/sRadius, r = 1.6 mAs we know the formula,
→ [tex]\Sigma f = ma[/tex]
or,
→ [tex]\Sigma f = \frac{mv^2}{r}[/tex]
By putting the values, we get
[tex]= \frac{52\times 8^2}{1.6}[/tex]
[tex]= \frac{52\times 64}{1.6}[/tex]
[tex]= 2080 \ N[/tex]

A 1500 kg car is being lifted by a hydraulic jack attached to a flat plate. Underneath the plate is a pipe with radius of 24 cm at the top and 2cm at the bottom. To generate an upward acceleration for the car of 1.0 m/s2, how much force must be applied to the small end of the pipe? The answer is NOT 102 N btw
Answers
Answer:
The force that must be exerted at the other end is 102.08 N/m₂
Explanation:
Using Pascal's formula; P₁ = P₂
P₁ = F₁/A₁ = m*g/(πr²)
m = 1500 kg; g = 9.8 m/s², r = 24 cm = 0.24 m
P₁ = (1500 * 9.8)/(22/7 * 0.24 * 0.24)
P₁ = 81235 N/m²
P₂ = F₂/A₂
A₂ = πr² where π = 22/7; r = 2.00 cm = 0.02m
A₂ = 22/7 * 0.02 * 0.02 = 0.00126 m²
P₂ = F₂ / 0.00126 m₂
substituting in the formula P₁ = P₂
81235 N/m² = F₂ / 0.00126 m²
F₂ = 81235 N/m² * 0.00126 m²
F₂ = 102.08 N/m₂

Answers
Answer:
Iris
Explanation:
Iris can be described as a part of the eyes which regulates the amount of light that enters the eye. The iris is made up of various muscles that control the size of the pupil
When a person is in a well-lighted room, the iris decreases the size of the pupil so that a low amount or medium amount of light is absorbed into the pupil. Also when an individual steps into a dark room the iris increases the size of the pupil so that a high amount of light penetrates the pupil.
Hence without the iris the amount of light that enters the eye cannot be controlled.
