To examine and characterize matter, employ its physical qualities. Physical characteristics include things like shape, feel, color, smell, melting temperature, boiling point, density, solubility, polarity, and a host of other things.

Any measurable attribute that characterizes the condition of a physical system through its values is referred to as a physical property. The transitions between a system's brief states can be described by changes in physical characteristics of the system.

Measurements are a common nickname for physical characteristics. The properties are not modal. Physical amount refers to that of an identifiable physical characteristic.

Physical characteristics are often divided in intensive and extensive properties. Whereas an extensive property exhibits an additive relationship, an intensive property is independent by the system's size, scope, or the volume of its constituent parts. These categories are typically only relevant when the sample's smaller subgroups do not interact physically or chemically when combined.

Answer: A

Explanation:

When thrown from the balloon, the sandbag has a constant horizontal/forward velocity. As the text puts it, "the sandbag continues forward as if it had not been dropped." What this means is that the sandbag has no acceleration in the horizontal plane of motion, so it moves in this direction at a constant speed. So for any time \(t\), the horizontal velocity is given by

\(v_x(t) = 12\dfrac{\rm m}{\rm s}\)

In the vertical plane of motion, the sandbag has no vertical velocity until it's released and allowed to fall. As it's falling, however, the sandbag is being pulled down by gravity and is accelerating with magnitude \(g=9.8\frac{\rm m}{\mathrm s^2}\), so its vertical/downward velocity at time \(t\) is given by

\(v_y(t) = -gt\)

So, after 3 seconds have passed, the sandbag has horizontal velocity \(v_x = 12\frac{\rm m}{\rm s}\) and vertical velocity \(v_y = -g(3\,\mathrm s) = -29.4\frac{\rm m}{\rm s}\). If the question is specifically asking about speed you would just ignore the negative signs.

The law of conservation of matter and the law of conservation of energy essentially state that neither type of energy can be created nor destroyed, only transformed. The process by which grapes ferment to produce wine is an illustration of the law of conservation of matter. The amount of matter in the reactants in the bottle doesn't change, but its chemical form does.

It is a fundamental tenet of classical physics that matter cannot be created or destroyed in an isolated system; rather, it can only be changed from one form to another. This means that despite the apparent changes that are seen, no matter is lost during any chemical or physical change that may occur with any substance.

The bicyclist's acceleration is 2.7 m/s². Thus, Option C is the answer

Acceleration is defined as rate of change of velocity with time. Its formula is

a= \(\frac{vf - vi}{t}\)

acceleration = (final velocity - initial velocity) / time

The bicyclist's acceleration can be found using this equation:

In this case,

final velocity = 12.15 m/s

initial velocity is 0 m/s (since the bicyclist starts from rest)

time = 4.5 s

Plugging these values into the equation, we get:

a =\(\frac{12.5 - 0}{4.5}\)

a = 2.7 ms⁻²

Therefore, The correct answer is c. 2.7 m/s²

Independent Variable:  student alone or with others

Dependent Variable:   how funny student thought the cartoon was

Answer:

Independent Variable: Watching cartoon alone or with others

Dependent Variable: how funny they found the cartoon to be

Explanation:

A dependent variable is the variable being tested. The change in the value of dependent variable depends on the independent variable.

An independent variable is used to test the effects on dependent variable and its does not depend on any variable.

In the above example the dependent variable is how funny the cartoon was. This is being tested and it is tested by independent variable i.e. Students watching cartoon either alone or with others. So the cartoon is funny or not depends on watching cartoon alone or with friends.

For two nucleons 2 femtometers (fm) apart, the strong force is attractive. The strong force, also known as the strong nuclear force or strong interaction, is one of the four fundamental forces in nature.

It is responsible for binding protons and neutrons (collectively called nucleons) together in atomic nuclei. This force is attractive at short distances (around 1-3 femtometers), and it overcomes the electrostatic repulsion between positively charged protons. As the distance between the two nucleons decreases, the intensity of the pion exchange increases, and so does the strength of the attractive force. This is why the strong force is so effective at binding the nucleons together in the nucleus of an atom.

It would weigh less bc the higher you are the less gravity there is.

In this case, we need to know the buoyant force acting on the submerged log. The buoyant force, also known as Archimedes' principle states that the buoyant force acting on a body submerged in a fluid is equal to the weight of the displaced fluid. Mathematically,

Fb = ρ × V × g

where, Fb is the buoyant force

ρ is the density of the fluid

V is the volume of fluid displaced

g is the acceleration due to gravity (9.81 m/s²)

Let's find the volume of fluid displaced, V using the mass of the log.

Mass of the log = 390 kg

Since the log is completely submerged, it displaces its own volume of fluid. The volume of the log is given by;

Vlog = mlog/ρlog

where, ρlog is the density of the log

Since the log is made of ebony wood, the density of the log is

ρlog = 710 kg/m³

Therefore,

Vlog = mlog/ρlog = 390/710 = 0.549 m³

We can now find the buoyant force acting on the submerged log.

Fb = ρ × V × g

where, ρ is the density of water which is about 1000 kg/m³ (since the fluid is water)

g is the acceleration due to gravity (9.81 m/s²)

V is the volume of fluid displaced

Fb = 1000 × 0.549 × 9.81 = 5385.39 N

Therefore, the buoyant force acting on the submerged log is 5385.39 N.

We created models in three dimensions that depict the particles involved in nuclear reactions using plastic spheres, tiny beads, and strings of different colors.

The models provide an exact representation of the atomic nucleus, including its protons, neutrons, and the attractive and repulsive forces existing between them.

The utilization of LED lights was employed as a representation of the discharge of energy. The fission, fusion, and radioactive decay were effectively exhibited by the models. Despite their usefulness, simplified models have limitations in that they cannot fully capture the intricate dynamics at the atomic level.

To enhance the effectiveness of the models, we propose the integration of more complex intricacies, utilization of cutting-edge materials such as magnets, the inclusion of interactive components, and garnering valuable feedback from both users and educators.

These improvements would heighten precision, authenticity, and educational worth. Pictures exhibit the models along with their arrangements.

The large terrestrial planet never formed in the region of the asteroid belt because there was never enough mass there. Thus, option (a) is the answer.

Rocky planetesimals survived in the asteroid belt between Mars and Jupiter because they did not accrete into a planet. Jupiter's gravity, through the influence of orbital resonances, stirred up asteroid orbits and thereby prevented their accretion into a planet.

Jupiter's gravity is so strong, that it makes asteroid orbits within the Kirkwood gaps unstable. It's these gaps that prevented a single planetary body from forming in that region. So, because of Jupiter, asteroids formed into families of debris, rather than a single planetary body.

A magnet is a substance that creates an unseen zone where other magnetic materials can experience a force (either attracted or repulsive).

A magnet is any item that generates its own magnetic field and interacts with other magnetic fields. A magnet has two poles, the north pole as well as the south pole. The magnetic field of a magnet is depicted by field lines that start at its north pole but stop at its south pole.

Most permanent magnets have iron, chromium, perhaps cobalt as their principal metals. Cobalt, nickel, and aluminum are combined to form the alloy known as Alnico.
