Since Jason plays a lot of sports (D), there's a good chance that he has developed a greater-than-average lung capacity.  This is a good thing.

Jason likely took fewer breaths to blow up his balloon because he plays a lot of sports, which can lead to a higher lung capacity. This is not a definite answer, as other factors outside of the given options could also influence lung capacity.

The most probable reason, among the options given, why Jason took fewer breaths to blow up his balloon is option D: Jason plays a lot of sports. People who regularly engage in sports and physical activity often develop powerful lungs and a higher lung capacity. This means they can hold more air in their lungs at any given time, so they would need fewer breaths to blow up a balloon compared to those with lesser lung capacity. Please note, though, that there may be other factors not listed in the options that could affect how many breaths it takes to blow up a balloon.

Shield volcanoes are typically tall and broad, with flat, rounded shapes. They typically have a 5°-10° slope, and are typically made by lava flowing at a low viscosity (lava flowing easily), and their broad profile is typically built with flow after flow of relatively basaltic lava issuing from vents or fissures on the surface.

I hope this helps, I got a bit confused on the composition part as well.

Shield volcanoes usually have a broad shape, gentle slope and a basaltic composition.

Shield volcanoes are very known for their expansive and gently sloping profiles which are predominantly composed of basaltic lava. Their distinctive form arises from the eruption of low-viscosity magma which flows easily across the landscape.

These volcanic giants do stretch across tens of kilometers in diameter, with their broad and shield-like appearance earning them their name. The effusive nature of their eruptions characterized by the steady release of lava, contributes to their gradual slopes.

The faster the particles are moving, the more energy they have. Temperature is the average amount of energy of motion of each particle of a substance. That is, temperature is a measure of how hot or cold a substance is. In contrast, the total energy of motion in the particles of a substance is called thermal energy.

The total energy of all the particles in a substance is called the internal energy (U) or symbolized as E. It is the sum of the kinetic energies and potential energies of the system's constituent particles.

The total energy of all the particles within a substance is referred to as the internal energy, often denoted as U or E. This internal energy encompasses both kinetic and potential energy, and it plays a crucial role in understanding the behavior and properties of substances.

1. Kinetic Energy: This component of internal energy is attributed to the motion of the particles within the substance. It includes various forms of motion, such as translational (linear motion), vibrational (vibrational motion of atoms or molecules within a structure), and rotational (rotational motion of molecules). The kinetic energy is directly related to the temperature of the substance, as an increase in temperature leads to higher kinetic energy of the particles.

2. Potential Energy: The potential energy component arises from the relative positions of particles within the substance, their interactions, and the conditions of the system. This can encompass various forms of potential energy, such as chemical potential energy (related to chemical bonds and reactions) and intermolecular potential energy (associated with attractive and repulsive forces between particles). Changes in potential energy can result from changes in the arrangement or composition of particles.

Together, these components contribute to the overall internal energy of the system, influencing its thermodynamic properties and behavior. Understanding the interplay between kinetic and potential energy is fundamental in fields like thermodynamics and chemistry, as it helps elucidate the physical and chemical transformations of substances.

8. Picture B

Explanation:

There are 3 states of matter:

- Solid: in solids, atoms/molecules are bond together, so they are not free to move, they can just vibrate around their fixed positions. In solids, atoms/molecules are close and packed with each other

- Liquid: in liquids, atoms/molecules can move past each other, however there are still intermolecular forces that keep them close to each other

- Gas: in gases, atoms/molecules are totally free to move far from each other

In this case, atoms in the gas of a neon sign are represented by picture B, since there the atoms are very far from each other and free to move.

9. Picture C.

Explanation:

the picture that best represents a rock is picture C: in fact, we see that in picture C atoms are packed and close to each other, since it is a solid and atoms are bond to each other. So, picture C represents a solid, therefore it is the picture that best represents a rock.

The sun is the original source of energy

because the plants feed from the sun and the animals eat the plants and then the animals eat the plant eating animals.

The original source of energy in a food web is the sun, captured by producers via photosynthesis and passed through the food chain to carnivores like cats, with energy loss in the form of heat at each step.

The original source of energy that transfers through a food web to meat-eating animals such as a cat is the sun. Energy from the sun is captured by producers, like plants, through photosynthesis, where it is converted into carbohydrate molecules. Herbivores, or plant-eating animals, consume the plants and absorb the stored energy. When carnivores, such as cats, prey on these herbivores, they receive the energy that originated from the photosynthetic plants. Eventually, decomposers participate in breaking down dead organisms and contribute to the nutrient cycle. Throughout this energy transfer process, some energy is inevitably lost as heat.

Answer: a

Explanation:

The following combination is not feasible to be in equilibrium : 10,10,10

The correct option is A.

A state in which opposing forces or influences are balanced is called equilibrium.

The addition of two smaller forces must be greater than the third force in case of three forces to be in equilibrium.

For A: 10 + 10 >10 or 20 > 10

For B: 10 +5 <17 or 15 <17

For C: 5 +10 > 12 or 15 >12

For D: 5 +12 >13 or 17 >13

So, the gap between the magnitude of balancing forces is very high in (10,10,10).

Thus, the correct option is A.

I think the answer is B...

If an object is traveling with a constant velocity, there is no net force on the object.

If an object is traveling with a constant velocity, it means the object is moving in a straight line with a constant speed. In this case, the correct ending for the sentence is B. There is no net force on the object. This is because an object moving with a constant velocity experiences balanced forces, where the forces in all directions cancel each other out. Therefore, the object continues to move with the same velocity.

mafic or intermediate

Descabezado Grande is a composite volcano primarily composed of intermediate andesite lava.

The volcano Descabezado Grande is characterized by a composite of various eruption styles, including low viscosity mafic magma and higher viscosity felsic lava, but it is most commonly composed of intermediate andesite lava. This composition places it within the category of composite volcanoes, also known as stratovolcanoes, which feature steep sides and are made of alternating layers of pyroclastic materials and lava flows. The composition of the magma is crucial for determining the volcano's eruptive behavior and landform shape, with intermediate magmas having properties that are in between those of mafic and felsic magmas. Descabezado Grande's magma, being primarily intermediate, indicates a mix of characteristics that contribute to its explosive eruption style and the formation of steep slopes.

1) A chemical change is used by scientists to create new substances, and a physical change happens naturally. A chemical change results in a new substance being formed; whereas, a physical change will result in a different state of matter.

Answer:

Chemical changes involve the formation of a new substance.

Explanation:

The main difference between chemical and physical changes is the fact that chemical changes involve the formation of a new substance. When a physical change occurs, this does not lead to bonds being broken or formed. The properties of the elements involve do not change. This includes changes such as changes of state. On the other hand, a chemical change is one in which bonds are broken or formed. Therefore, the elements that are present are turned into a new substance.

If an experiment is replicsble it means that anybody can repeat the experiment and get the same results. It is important that experiments be replicable because if someone else can't repeat what you did, you might have made a mistake. Peer review is what scientists use.

hope this helps

A replicable experiment can be repeated under the same conditions to provide similar results. This is crucial in the scientific method as it ensures reliability of results, allows for verification of the findings, and helps weed out false claims. The inability to replicate an experiment often leads to questioning the credibility of the initial study.

When an experiment is replicable, it means the experiment can be repeated by others under the same conditions and produce the same or very similar results. This ability to reproduce results is one of the essential features of the scientific method, which is used in various fields of academic research, including physics, chemistry, biology, and psychology.

Replicability is essential for several reasons. First, it ensures the reliability of results. Results that are repeated in independent replications are considered more reliable because they have been tested and verified multiple times. Second, replication allows other researchers to check for any mistakes in the original study. Third, successful replications of research provide more evidence to support the original findings, leading to a wider acceptance of the results within the scientific community.

Conversely, if subsequent studies cannot replicate the findings, it may call the credibility of the original research into question.

Through this rigorous process of repeated testing, scientific knowledge advances as false claims are weeded out and factual information is reinforced.

Answer:

The pressure of the gas will be increased to 450 kilo pascals.

Explanation:

Since the temperature is kept constant, the volume and pressure will be related by Boyle's Law.

According to the Boyle's Law, the product of pressure and volume of a gas remains constant provided that the temperature remains constant.

Mathematically this cab be expressed as:

[tex]P1V1 = P2V2[/tex]

Using the given values,

P1 = 300 kilo pascals

V1 =75 L

P2 = ?

V2 = 50 L

[tex]300 \times 75 = 50 \times P2\\ \\P2 = \frac{300 \times 75}{50}\\\\ P2= 450[/tex]

This means the pressure of the gas will be increased to 450 kilo pascals.

[tex]F=k\frac{q_1 q_2}{r^2}[/tex]

where

k is the Coulomb's constant

q1 and q2 are the charges of the two objects

r is the separation between the two objects

In this problem, we have that the charge of one object is quadrupled:

[tex]q_1'=4q_1[/tex]

while all the rest remain unchanged. So the new electric force between the two objects is

[tex]F'=k\frac{q_1' q_2}{r^2}=k\frac{(4q_1) q_2}{r^2}=4 k\frac{q_1 q_2}{r^2}=4F[/tex]

So, the force will quadruple as well.
