1. The force due to gravity acting on an object is called what?
Answer:
Near the surface of the earth such objects are accelerating. This acceleration is due to the gravitational force acting between the objects and the earth. ... It points straight downward towards the center of the earth. The force of gravity acting on an object is called its weight.

match the quote about working in government to the correct branch. Then name
the article that describes the powers of this branch.(Giving Brainlist and doubling points for Correct answer!)
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.

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
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.
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.
what is the role of neutrons in the nucleus.
Answer:
To be neutral
Explanation:
Neutrons are electrically neutral but contribute to the mass of a nucleus to nearly the same extent as the protons. Neutrons can explain the phenomenon of isotopes (same atomic number with different atomic mass). The main role of neutrons is to reduce electrostatic repulsion inside the nucleus.
Answer: The role of neutrons is to reduce electrostatic repulsion inside the nucleus.
Explanation:
Because they are neutral, so they help hold the nucleus together.

A 40-gram block of copper at 95*C is placed in 105 g of water at an unknown temperature. After equilibrium is reached, the final temperature of the water is 24*C. What was the initial temperature of the water?
The initial temperature of the water was approximately 81.67°C.
To solve this problem, we can apply the principle of energy conservation. The heat lost by the copper block is equal to the heat gained by the water.
The heat lost by the copper block can be calculated using the formula: Q1 = m1 * c1 * ΔT1,
where m1 is the mass of the copper block (40 g), c1 is the specific heat capacity of copper (0.39 J/g°C), and ΔT1 is the change in temperature (final temperature - initial temperature of the copper block).
The heat gained by the water can be calculated using the formula: Q2 = m2 * c2 * ΔT2, where m2 is the mass of the water (105 g), c2 is the specific heat capacity of water (4.18 J/g°C), and ΔT2 is the change in temperature (final temperature - initial temperature of the water).
Since the copper block and the water reach equilibrium, Q1 = Q2. Therefore, we can equate the two equations:
m1 * c1 * ΔT1 = m2 * c2 * ΔT2
Substituting the given values:
(40 g) * (0.39 J/g°C) * (95°C - initial temperature) = (105 g) * (4.18 J/g°C) * (24°C - initial temperature)
Simplifying the equation and solving for the initial temperature of the water gives us approximately 81.67°C.

What is the name for the amount of energy transferred every second by an electrical appliance?
The most appropriate term used for the amount of energy transferred every second by an electrical appliance would be electric power.
What is power?The rate of doing work is known as power. The Si unit of power is the watt.
Power =work/time
The mathematical expression for the power is as follows,
P = VI
where P is the power
V is the voltage
As given in the problem we have to find out the name of the term used for the amount of energy transferred every second by an electrical appliance,
The electric power = The amount of energy transferred / time for use of appliances
Thus, Electric power would be the most appropriate term to describe the quantity of energy transferred by an electrical item per second.

Explanation:
Mechanical energy that has been ‘lost' to friction isn't really lost. It just is no longer in its mechanical form. True or False
Answer:
True.
Explanation:
Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Furthermore, the mechanical energy of a physical object or body is the sum of the potential energy and kinetic energy possessed by the object or body.
Mathematically, it is given by the formula;
Mechanical energy = G.P.E + K.E
Mechanical energy that has been ‘lost' to friction isn't really lost. It just is no longer in its mechanical form. This is ultimately in accordance with the law of conservation of energy, which states that energy cannot be destroyed but can only be converted or transformed from one form to another.
Hence, Mechanical energy that has been ‘lost' to friction isn't really lost but converted into heat energy.
