Deffense [45]2 years ago

Answer:

C. Fe will stay positive and increase in magnitude.

Explanation:

Coulomb's law states that the force of attraction of repulsion between two charged particles is directly proportional to the magnitude of their charges and inversely proportional to the square of the distance of separation between them.

This means that if the size of the charges are large, the force acting on them will be large as well. Also if the distance between the two charges increases the force decreases. However, the force increases when the distance of separation decreases.

Like charges repel, therefore, two negative charges brought together will repel each other, and the distance between the two charges decreases, the force will increase in magnitude. Forces of repulsion are considered positive, therefore, the force, Fe, will stay positive and increase in magnitude.

Which of the following materials is useful for making molds because it has a low melting point?
inessss [21]
<span>Molds are created to achieve a specific design of a material. These materials either came from a process of having a higher or lower temperature. Therefore, the molder must have thermal resistant properties. Low melting points means that the material to be shaped came from a cooler process. Wood and metal have higher thermal conductivity and therefore can easily be cooled. The wax can turn really hard and can be unbreakable when present in colder materials due to the lipids present in it. Clay however can become a mold because of its low melting point.</span>

Why does random error affects precision?​
djyliett [7]

Answer:

Thus, random error primarily affects precision. Typically, random error affects the last significant digit of a measurement. The main reasons for random error are limitations of instruments, environmental factors, and slight variations in procedure.

Describe the many different forms of energy involved with stretching and releasing a rubber band. What other processes are simil
Nadya [2.5K]

Answer:

Conversion of kinetic energy to potential energy (chemo mechanical energy)

In the state of rest, the rubber is a tangled mass of long chained cross-linked polymer that due to their disorderliness are in a state of increased entropy. By pulling on the polymer, the applied kinetic energy stretches the polymer into straight chains, giving them order and reducing their entropy. The stretched rubber then has energy stored in the form of chemo mechanical energy which is a form of potential energy

Conversion of the stored potential energy in the stretched to kinetic energy

By remaining in a stretched condition, the rubber is in a state of high potential energy, when the force holding the rubber in place is removed, due to the laws of thermodynamics, the polymers in the rubber curls back to their state of "random" tangled mass releasing the stored potential energy in the process and doing work such as moving items placed in the rubber's path of motion such as an object that has weight, w then takes up the kinetic energy 1/2×m×v² which can can result in the flight of the object.

Somebody help me with this please very much appreciated
Flauer [41]

The answer for the following answer is explained below.

The answer is NH_{4} ^{+}

Explanation:

Bronsted-Lowry acid :

It is a solution that donates protons, and is known as a proton donor.It donates protons in the form of hydrogen ion(H^{+}).This is reinforced by the definition of an acid ,which is a solution that has hydrogen ions.

In Bronsted-Lowry aci it must contain a hydrogen io that it can give up.When the acid gives a hydrogen ion,the charge of an acid decreases.

Here,

NH_{4} ^{+}  loses one hydrogen ion and forms ammonia molecule.

So therefore the Bronsted-Lowry acid  is NH_{4} ^{+}.
