White color is the result of adding various combinations of red, green, and blue primary light colors in equal intensities.
What are primary colors?The three primary colors are Red, green, and blue. This implies that by additively combining the colors red, green, and blue in varied proportions the different color is obtained.
Practically all other colors may be made, and when the three primaries are mixed together in equal amounts, white is produced.
Hence white color is the result of adding various combinations of red, green, and blue primary light colors in equal intensities.

A loaded spring undergoes simple harmonic motion whose period is proportional to the mass and inversely proportional to the spring constant.
What is simple harmonic motion?Simple harmonic motion is the periodic motion of an object along a straight line, such that the acceleration of the object is directed towards a fixed point on that line and is proportional to its distance from that point.
Example of a simple harmonic motion is the motion of a loaded spiral spring.
The restoring force on the spring is directly proportional to the extension of the spring and the spring constant.
The period of motion, T when a mass, m is attached to a spring with spring constant k,is given as:
T = 2π√(m/k)Therefore, a loaded spring undergoes simple harmonic motion whose period is proportional to the mass and inversely proportional to the spring constant.

On top a coiled spring labeled wave a with coils, which are widely spaced then tightly spaced then widely space. on bottom a coiled spring labeled wave b with coils, which are widely spaced then very tightly spaced then widely space. which statement can be made about waves a and b? wave a has a lower amplitude than wave b. wave a has a higher amplitude than wave b. wave a has a lower frequency than wave b. wave a has a higher frequency than wave b.
Answer:
Wave A has a lower frequency than Wave B.
Explanation:
Frequency is the number of waves passing through the unit time.
As the statement of the question says that the coils in wave A are widely and tightly spaced.
While in wave B the coils are widely and very tightly spaced which means the number of coils is more and the frequency of wave B is more than wave A.
Therefore more coils will pass through a fixed point in unite time and more will be the frequency.
Answer:Wave A has a lower frequency than Wave B.

An object is at rest on a tabletop. Earth pulls downward on this object with a force equal in magnitude to mg. What is the interaction pair to this force
Answer:
normal contact force
Explanation:
that is the equal and opposite force (as to weight) applied by the table on to the object.
The gravitational force of the earth on the object and the reaction force of the table on the object interact as a pair of forces.
What does gravity mean?The gravitational force is what pulls things with mass in the same direction. People commonly think about the Earth's gravitational pull. Your body is kept on the ground by this force. Yet, gravity pulls all objects with mass in the same direction.
The gravitational force, or g, is the force that the earth exerts on an object, with g equal to 9.8 m/s2.
The information is ,
Place something on the table.
Now that the item is at rest, a force known as gravitational force pushes it downward from the Earth.
The formula for gravitational force is F = mg, where m is the object's mass.
Moreover, Newton's third law states that every action will always have a corresponding and opposing reaction. When the gravitational force acting between two masses is equal in strength and conducted in the opposite direction, an action and reaction pair is produced.
The reaction force is then given by R = -mg, where m is the object's mass and the negative sign denotes that the force is acting in the opposite direction to that of gravity by earth.
Hence , the interaction pair for gravitational is the reaction force

What is the function (job) of the genes in protein synthesis (how proteins are made in the cell)?
Answer:
Most genes contain the information needed to make functional molecules called proteins. A few genes produce regulatory molecules that help the cell assemble proteins.
To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.
