Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semiangle of inclination between those two lines.

Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semiangle of inclination between those two lines. The term is derived from the Greek word παράλλαξις (parallaxis), meaning "alternation". Due to foreshortening, nearby objects have a larger parallax than more distant objects when observed from different positions, so parallax can be used to determine distances.
To measure large distances, such as the distance of a planet or a star from the earth, astronomers use the principle of parallax. Here, the term "parallax" is the semiangle of inclination between two sightlines to the star, as observed when the Earth is on opposite sides of the Sun in its orbit. These distances form the lowest rung of what is called "the cosmic distance ladder", the first in a succession of methods by which astronomers determine the distances to celestial objects, serving as a basis for other distance measurements in astronomy forming the higher rungs of the ladder.

It's a short range force called the strong force.
Explanation:
As you may know, the proton is not an elementary particle, it is made of three quarks plus a sea of gluons. Gluons are the elementary particles that transmit the strong force. Particles that are sensitive to the strong force carry one of three colors.
The term color here refers to a quantum number that is more like a charge. it is only because there are three strong charges and three fundamental colors that by analogy, the strong charge is called the color. The strong force, unlike the electromagnetic force, is confining. That is a proton cannot be broken in free quarks. These are always bound.
The strong force, at the distances of the order of the proton radius, is 60 times stronger than the electromagnetic forceThanks (0)

No, it is not possible.Thanks (0)

Answers:

It is a point from which the weight of a body or system may be considered to act. In uniform gravity, it is the same as the centre of mass.

Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all nonaccelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels.
Albert Einstein's general theory of relativity is one of the towering achievements of 20thcentury physics. Published in 1916, it explains that what we perceive as the force of gravity in fact arises from the curvature of space and time. Einstein proposed that objects such as the sun and the Earth change this geometry.
Special relativity is a theory proposed by Albert Einstein that describes the propagation of matter and light at high speeds. ... Special relativity reduces to Newtonian mechanics in the limit of small speeds. According to special relativity, no wave or particle may travel at a speed greater than the speed of light c.

The standard used for measurement is known as unitThanks (0)

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same quantity.Any other value of that quantity can be expressed as a simple multiple of the unit of measurement.
For example, length is a physical quantity. The metre is a unit of length that represents a definite predetermined length. When we say 10 metres (or 10 m), we actually mean 10 times the definite predetermined length called "metre".

Answers:

Acceleration, in physics, is the rate of change of velocity of an object with respect to time. An object's acceleration is the net result of any and all forces acting on the object, as described by Newton's Second Law. The SI unit for acceleration is metre per second squared (m s−2). Accelerations are vector quantities (they have magnitude and direction) and add according to the parallelogram law. As a vector, the calculated net force is equal to the product of the object's mass (a scalar quantity) and its acceleration.
