Answer: The force used on your arm when you walk a dog on a leash and it tries to chase something is known as Strong pull.Strong pull is defined a physical force which is usually aggressive orcoercive and it involves the movement in a particular direction due to different factors or reasons. The Dog in the example has a leash on and applies a force in the direction ofthe thing it wants to chase which is a perfect example of a strong pull.

I have 11 protons, which element am I?
A. Silicon
B. Fluorine
C. Argon
D. Sodium
Answer:
D. Sodium
Explanation:
We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass).
Water’s chemical formula is . One atom of bonded to two atoms of . The hydrogen atoms are to one side of the oxygen atom, resulting in a water molecule having a positive charge on the side where the hydrogens reside and a negative charge on the other side, where the oxygen atom resides. This separation
of charge on of the molecule is called

There is a big push right now in trying to rely on nonrenewable resources for the majority of our energy needs. Should we even try to power the world with 100% renewable resources? Justify your reasoning
Answer: Non-renewable energy comes from sources that will run out or will not be replenished in our lifetimes—or even in many, many lifetimes.
Most non-renewable energy sources are fossil fuels: coal, petroleum, and natural gas. Carbon is the main element in fossil fuels. For this reason, the time period that fossil fuels formed (about 360-300 million years ago) is called the Carboniferous Period.
All fossil fuels formed in a similar way. Hundreds of millions of years ago, even before the dinosaurs, Earth had a different landscape. It was covered with wide, shallow seas and swampy forests.
Plants, algae, and plankton grew in these ancient wetlands. They absorbed sunlight and created energy through photosynthesis. When they died, the organisms drifted to the bottom of the sea or lake. There was energy stored in the plants and animals when they died.
Over time, the dead plants were crushed under the seabed. Rocks and other sediment piled on top of them, creating high heat and pressure underground. In this environment, the plant and animal remains eventually turned into fossil fuels (coal, natural gas, and petroleum). Today, there are huge underground pockets (called reservoirs) of these non-renewable sources of energy all over the world.
Advantages and Disadvantages
Fossil fuels are a valuable source of energy. They are relatively inexpensive to extract. They can also be stored, piped, or shipped anywhere in the world.
However, burning fossil fuels is harmful for the environment. When coal and oil are burned, they release particles that can pollute the air, water, and land. Some of these particles are caught and set aside, but many of them are released into the air.
Burning fossil fuels also upsets Earth’s “carbon budget,” which balances the carbon in the ocean, earth, and air. When fossil fuels are combusted (heated), they release carbon dioxide into the atmosphere. Carbon dioxide is a gas that keeps heat in Earth’s atmosphere, a process called the “greenhouse effect.” The greenhouse effect is necessary to life on Earth, but relies on a balanced carbon budget.
The carbon in fossil fuels has been sequestered, or stored, underground for millions of years. By removing this sequestered carbon from the earth and releasing it into the atmosphere, Earth’s carbon budget is out of balance. This contributes to temperatures rising faster than organisms can adapt.
It is important that engineers build a structure that is safe. What do they look for when testing their designs?
Failure points
Fair tests
Prototypes
Variables
Answer:
Failure Points
Explanation:
Engineers want to test the areas that may possibly fail when they are building designs so when they go to actually build it they know it will not fail.

What does the conversation of mass say about the amount of atoms in the reactants compared to the products?
Answer:
the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.
Answer:
[tex]\boxed {\boxed {\sf Atoms \ in \ reactants \ = atoms \ in \ products}}[/tex]
Explanation:
The Law of Conservation of Mass states that mass cannot be created or destroyed.
In a chemical reaction, this means the mass of the reactants (substances going in and being changed) must equal the mass of the products (new substances from the reaction).
In addition, the amount of atoms must stay the same. The atoms can and will reconfigure to form different compounds, but the number of atoms stays the same.
How are the scientific method and the engineering method similar?
Both methods identify failure points.
Both methods construct a hypothesis.
Both methods focus on designing things.
Both methods work on finding solutions to problems.
The answer is Both methods work on finding solutions to problems. Because the science is trying to get the right thing and engineering is trying to solve the problem and get right thing and is the same with the science

What happens to potential energy when you move against the magnetic force?
Answer: The field produces a repulsive force pushing them apart. They repel each other. In this case, the closer they are, the higher their potential energy will be. If allowed to move, they may move as far apart as possible or one will swing around to change its orientation.

Materials move across a cell membrane in a process called _______.
Answer:
Diffusion
Explanation:
_____ relating to the separation of charges in a molecule
___ meaning to repel water, literally “fear of water”
___ this term describes the force of attraction between adjacent water molecules.
___ meaning attracted to water or literally “water loving”
___ term describing the tensional force created by water at its boundary with air
word bank: surface tension, cohesion, hydrophobic, hydrophilic, polarity
1. polarity
2. hydrophobic
3. cohesion
4. hydrophilic
5. surface tension
what do you mean by cohesion ?cohesion is an attractive force of measure where molecules are stick to each other and it is caused by cohesive force between like molecules.
It is an intrinsic property of a molecule, derived by its shape, structure, and electric charge distribution.
When cohesive molecules are become closer to each other, the electrical attraction between these molecule holds them together.
This forces are responsible for surface tension. For example mercury is a cohesive substance, strongly attracted to each other, bead together, sticks to itself when it flows.
When cohesion and adhesion combinedly work, it will lead to capillary action.
Hence, when water climbs up the interior of a thin glass tube or the stem of a plant, Cohesion holds the water together and adhesion helps the water molecules stick to glass.
