What seems to be the best way to get the 'puck (point charge)' into the goal More charges in the field
Answer:
We can find the electric field created by a point charge by using the equation E=kQr2 E = k Q r 2 .
Explanation:
The electric field of a point charge is, like any electric field, a vector field that represents the effect that the point charge has on other charges around it. If the charge is positive, field lines point radially away from it; if the charge is negative, field lines point radially towards it.

what part of the outer ear transmits sound by vibrating
The part of the outer ear that transmits sound by vibrating is the eardrum, also known as the tympanic membrane.
What is eardrum?Eardrum is the thin, circular eardrum is the thing that divides the inner ear from the outer ear.
The eardrum vibrates as a result of sound waves entering the ear canal and changing air pressure.
The middle ear is the place at which the eardrum vibrations are amplified and transported via the ossicles to reach the inner ear i.e., the three tiny bones called the malleus, incus, and stapes.
The cochlea, which is located in the inner ear, is in charge of turning these sound vibrations into neural impulses that the brain can comprehend.
Thus, the eardrum, sometimes referred to as the tympanic membrane, is the component of the outer ear that vibrates to transfer sound.

Which types of currents are caused by wind on the Earth's surface? deep-water currents surface currents
Answer:
Deepwater currents.Explanation:
During the rainy season, rivers may overflow their banks, flooding the area and causing great damage. What is one thing people can do to help reduce the impact of flooding and subsequent erosion?
A number of different methods can be used to prevent the damage caused by flooding including vegetation to retain excess water, terrace slopes to reduce the slope flow, and building dams, reservoirs or holding tanks to store extra water during flood.
What is Flood?Floods caused due to overflow of river due to excessive rainfall causes river to exceed its capacity. Floodwater can also alter the landscape, by riverbanks and causing them to collapse. As floodwater carries materials from the soil, it suspends the sediment in the water, which will degrade the water quality and hence lead to harmful blooms of algae
The flooding of a river is an example of unsteady and non-uniform flow of water. There are many different types of flow includes steady flow in which the fluid characteristics like velocity (V), pressure (P), density (ρ), etc. at a point do not change with time.

a random change in allele frequencies over time is known as
Answer:
Genetic drift
Explanation:
Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time. These variations in the presence of alleles are measured as changes in allele frequencies.
A random change in allele frequencies over time is known as "genetic drift." Hence, due to this, the allelic frequencies alter in a population over time.
What is genetic drift?A genetic drift changes the gene pool of a particular population. It is significant in a small population. Many factors such as migration, birth, and death affect the genetic pool. Some new genes are added to the gene pool as a result of genetic drift, while others are permanently lost. Increases in one allelic frequency replace the other allele.
In a small population of 20 animals, black skin is dominant over white. 12 are homozygous for black skin, 5 are heterozygous for black skin, and 3 are recessive and show white skin. If any natural calamities happen that destroy the white animals, then this allele will disappear from the population. After many generations, only black-skinned individuals will appear.
Hence, a random change in allele frequencies over time is called "genetic drift."

To model how particles move as states of matter change, Jelani filled a clear box with as many marbles as the box would hold. Then he drew a picture of what the box looked like with the marbles in it.
Part A
Jelani covered the box and shook it. He could barely feel the marbles moving around the box. What state of matter does Jelani's box of marbles represent? Explain.
Answer:
It represent the solid state. In the solid state, the atoms or molecules that compound a substance have a very organized shape, as you can see in the pic, and also the solid state is the state that the particles have the minimum degree of freedom, and that explains why he barely feel the marbles moving when he shook it, it's because in the solid state the particles move less than in the liquid or gas state.

Which type of RNA functions to use coded instructions to assemble amino acids?
mRNA
rRNA
tRNA
Ribosomes
The type of RNA that functions as coded instructions to assemble amino acids would be messenger RNA. Option 1.
What is mRNA?The mRNA is an acronym for messenger ribonucleic acid. It is the RNA that is synthesized directly from the coding strand of DNA. The strand act as the template for the synthesis of mRNA.
The mRNA sequence, therefore, is complementary to the sequence of the coding strand of DNA. In other words, the mRNA contains the genetic instructions of DNA but in an encoded form. The genetic codes are then translated to the respective amino acids during translation.
The amino acids are linked together by peptide bonds to form the primary structure of proteins. These are then folded to arrive at specific secondary protein structures.
In summary the mRNA functions as coded instructions to assemble amino acids.

if a parent cell has 6 chromosomes, how many chromosomes will be in each daughter cell after mitosis and cytokinesis?
Answer:
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.
Since parents cells have 6 chromosomes per cell, DNA replication will lead to 12 chromosomes and mitosis will divide this cell into two daughter cells with 6 chromosomes each.
What is mitosis?
Mitosis is a procedure where a single cell splits into two equal daughter cells (cell division). During mitosis, one cell divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn-out cells.
Thus, 12 chromosomes and mitosis will divide this cell into two daughter cells with 6 chromosomes each.

Microscopes are important tools. But do you know the difference between there microscopes and when to use each type?
The compound light microscope combines the power of lenses and light to enlarge the subject being viewed.
The stereo microscope allows an object to be viewed three-dimensionally under the lenses.
Very small, live cells, like bacterial cells should be viewed using a scanning electron microscope.
The scanning electro microscope produces high-resolution, sharp, black and white 3D images.
If your task was to dissect the mouth parts of a grasshopper, you would use a compound light microscope to assist you.
Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light.
Answer:
A scope built of two systems of lenses ... ==> Compound light microscope
The light compound microscope is composed by two groups of lenses. In the first one, the lens projects a real intermediate image which is enlarged and inverted to the focal plane of the eyepiece. In the second group, the eyepiece that behaves like a magnifying glass, gives an image of the intermediate image which is enlarged and inverted again.
Designed for studying cells and tiny slices... ==> Transmission electron microscope.
The transmission electron microscope is an electron microscope for viewing objects much smaller than cells.
The transmission electron microscope (TEM or TEM) uses a high-voltage electron beam emitted by an electron gun.
If sample preparation is longer and more demanding than for optical microscopy, the resolution offers an incomparable view of the structures. Transmission electron microscopy allows to visualize intracellular organelles, viruses, crystals ...
A microscope that has lower magnifying power .... ==> Stereoscope (dissecting microscope).
The stereomicroscope is a special type of magnifying glass, often called a binocular loupe.
It is a device intended primarily for observation at low magnification with lighting overhead. It allows especially stereoscopic perception, in relief, of small subjects.
The stereomicroscope should not be confused with a microscope equipped with a binocular head. The latter only provides two identical images, with a "flat" rendering.
A microscope which magnifies from magnification ranging from 20X to 30.000X... ==> Scanning electron microscope
Scanning electron microscopy (SEM) is an electron microscopy technique capable of producing high resolution images of the surface of a sample using the principle of electron-matter interactions.
This microscope consists of an electron beam scanning the surface of the sample to be analyzed which, in response, reemits certain particles. These particles are analyzed by different detectors that reconstruct a three-dimensional image of the surface.
