Abstract

Force, mass and acceleration are everyday words but often used inaccurately. Force is a physical influence, which when applied to an object causes it to accelerate in the direction from which it was applied. Mass is the amount of matter in an object and is expressed in kilograms. Acceleration is the rate of change of velocity of an object in the same straight line of the unbalanced force. When forces become balanced, there is no net force and therefore no movement. Newton’s second law links these three terms and concerns the effect that an unbalanced force has on the motion of an object. It states that the rate of change of velocity of an object is directly proportional to the force applied and takes place in the direction of the force. It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s2). Thus, an object of constant mass accelerates in proportion to the force applied. Gravity is the variable force of attraction between any two objects. All matter possesses gravitational ‘pull’ towards other matter. The amount of gravity between two objects is dependent on their mass and the distance between their centres. The word ‘weight’ in its proper context refers to the downward vertical force exerted on an object as a result of the earth’s gravity. An object with greater mass is therefore subjected to a greater gravitational force (i.e. it has greater weight).

Answer:

net force

Explanation:

The net force acting on an object is the combination of all of the individual forces acting on it. ... If two forces act on an object in the same direction, the net force is the sum of the two forces.

Answer:CO2(g) will be formed at a faster rate in experiment 2 because more H+ particles can react per unit time

Explanation:

[tex]CO_2_{(g)}[/tex] will be formed at a faster rate in experiment 2 because more H+ particles can react per unit time. The correct option is C.

A chemical reaction is a process that transforms one or more substances, known as reactants, to one or more different substances, known as products. Chemical elements or compounds are examples of substances.

Combination, decomposition, single-replacement, double-replacement, and combustion are the five basic types of chemical reactions.

Analyzing the reactants and products of a specific reaction will allow you to categorize it. Some reactions will fall into multiple categories.

If both experimental studies are carried out with finely powdered samples of the solid and 50.0mL of HCl (aq), then [tex]CO{_2_{(g)}[/tex] will be formed at a faster rate in experiment 2 because more H+ particles can react per unit time.

Thus, the correct option is C.

Answer:

when a substance is heated it gains thermal energy. Therefore its particles move faster and its temperature rises. when a substance is cool it loses thermal energy which causes its particles to move more slowly and its temperature to drop

A substance gains thermal energy when it is heated. As a result, its temperature increases, and its particle motion accelerates.

Thermal energy is the heat energy that is given to a substance when its temperature is increased.

As we know, all matter are made up of atoms, and atoms are made up of charged particles. These particles become random or come in motion when they get thermal energy or heat.

When substances get thermal energy or heat energy. They become active, and the particles move apart from each other.

So, due to thermal energy, the atoms become loose, and the substance loses its shape, the temperature decrease the atoms come closer to each other.

Thus, when a substance cools, thermal energy is lost, which slows down the movement of its particles and lowers the substance's temperature and vice versa.

Answer:

D because electron is negatively charge around the nucleus

electrons are found outside the nucleus

An atoms is composed of electrons, protons and neutrons. Protons and neutrons are attached within the nucleus whereas electrons are in the cloud around the nucleus. Thus, option D is correct.

Atoms are the basic units of every substance. Atoms are composed of subatomic particles electrons, neutrons and protons.  Protons and neutrons are located inside the nucleus where as electrons are revolving around the nucleus.

The core of an atom is called nucleus. The protons are positively charged and the neutrons are neutral. Electrons are negatively charged particles and they are revolving around the nucleus through circular paths of fixed energy called orbits.

The region where we can find an electron inside an atom is called an orbital. Electrons experience an attractive pull  from the positively charged nucleus and thus electrons are existing in a cloud of electrostatic force around nucleus.

Answer:

2gcm⁻³

Explanation:

Given parameters:

Mass of the object  = 20g

Volume = 10mL

Unknown:

Density of the object  = ?

Solution:

Density of a body is its mass per unit volume;

   Density  = [tex]\frac{mass}{volume}[/tex]  

We need to convert mL to cm³ for the volume

     1mL  = 1cm³;

        10mL is therefore, 10cm³  

So;

       Density  = [tex]\frac{20}{10}[/tex]   = 2gcm⁻³
