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.

Answer:

10.4mm

Explanation:

2 pages = 1 leaf

200 pages = 100 leaves

100 × 0.10 = 10 mm thickness

Total thickness = 2(0.20) +10 = 0.4+10 = 10.4mm

Answer:

my first reason is that Mercury is the only one in liquid state at room temperature and thermometers because it has high coefficient of expansion . my second reason is that mercury its can changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale, and also Mercury thermometers can be used to determine body, liquid, and vapor temperature.

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.

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.

A wedge is like a ramp that can work while in motion.

As a tool for raising or lowering a load, an inclined plane, also referred to as a ramp, is a flat supporting surface that is tilted at an angle from the vertical direction with one end higher than the other. One of the six traditional simple machines that Renaissance scientists defined is the inclined plane.

Heavy loads are transported over vertical obstacles using inclined planes. Examples include a ramp used to load cargo into a truck, a pedestrian ascending a ramp, or an automobile or train ascending a grade.

Less force is needed to lift an object up an inclined plane than to lift it straight up, but the distance travelled is greater. Hence, a wedge is like a ramp that can work while in motion.

Where

m is the mass of a particle

A is the amplitude

x is the distance

[tex]\omega[/tex] is the angular frequency

The kinetic energy of a particle executing SHM is maximum at its equilibrium position and minimum at a maximum displacement from the equilibrium point.

The most appropriate term used for the amount of energy transferred every second by an electrical appliance would be electric 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.

boiling point is directly proportional to air pressure. as the air pressure decreases due to increase in elevation, boiling point of the water on top of a mountain would be less than the boiling of water at sea level

Explanation:

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.

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

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.

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.
