The process where the plants prepare their own FOOD through SUNLIGHT is CALLED as PHOTOSYNTHESIS

The COPERNICAN Revolution was the paradigm SHIFT from the Ptolemaic model of the heavens, which described the cosmos as having Earth STATIONARY at the center of the universe, to the heliocentric model with the Sun at the center of the Solar System.Explanation:it difficult for people to accept a heliocentric concept of the solar system? Because the THEORY of Heliocentrism is contrary to the theory of Geocentrism which places the Sun as the center of the solar system. In contemporary science, we can know that the sun is the CORE or axis of the Milky Way galaxy. And there are many other galaxies that are millions of light-years away from the Milky Way

We can look at this question from two perspectives. One in a mathematical sense and one in an intuitive and logical sense. The mathematical calculations are built on the basic axioms but it's important to understand why it follows logically. Once we have done that we can also confirm it through the math.Logical ApproachFirst let's start by defining potential. It's important to know what it means.Potential energy of a charge kept at a point is the negative of the work done on a body to bring it slowly from infinity to that point.So BASICALLY if you have a place with many charges and stuff, the body will experience some FORCE while you are bringing it from infinity. So you will have to do apply some force and thus do some work to make sure it moves slowly. The negative of the work done by you is the potential energy of the charge at the point.The potential of an unit charge kept at a point is the potential of that point.Now imagine that you have kept a positive unit test charge Q midway between A and B. The two charges kept at A and B are both equal and equidistant from Q. So both the charges pull on Q equally. So we can expect Q to not move at all.Now we know that the force on between two charges is inversely proportional to the square of the distance between them. So if we have two charges placed closer to each other, they will pull/push each other with a stronger force than if they were farther away.Now imagine that you place it closer to the point A.The test charge and the charges at A and B are all positive. So we would expect them to repel each other. So the charges Q and A will push each other away harder than the charges Q and B would. So the charge Q will experience a stronger force away from A and so will have a tendency to move towards B.Now let's say the points A and B are fixed and Q is allowed to move. So we should expect to see the charge Q accelerate towards B until it reaches the midpoint. At the midpoint, it's going to be in equilibrium, i.e. no force acts on it. However it is already moving towards B with some speed. So it just continues on towards B. However when it crosses the mid point, it is now closer to B. So now B pushes it harder. So it slows down till it stops and then starts accelerating towards A. Then it again crosses the midpoint and the same thing happens again.One of the basic laws of nature states that any body wants to move from higher energy to lower energy.We have SEEN that the unit charge wants to move from any point between A and B towards its midpoint. And at the midpoint if it doesn't have a velocity, it won't move ANYWHERE. As everything wants to lower its energy, we can say that the surroundings points are at a higher energy while the midpoint has the lowest energy. So we can imagine that the midpoint is like a valley between two hills, like a sink.So it logically makes sense that the potential (the potential energy of an unit charge) decreases as we move from A to the midpoint and then increases as we move from the midpoint to B.Mathematical ApproachThe potential due to a charge Q is kQ/r , where r is the distance of the point from the charge and k is the constant 1/(4πε) .Let the distance between A and B be d . So the potential (V) of a point at a distance r along the LINE joining A and B is (kq /r)+(kq/(d−r)) , where q is the charge of A and B.Therefore,V(r) =kq(1/r+1/(d−r))=kqd/(r.(d−r)) The graph of V with r is -Where the potential is along the y axis and the distance r is along the x axis.So we can see that the potential decreases and then increases on moving from A to B.

Explanation:Newton's LAWS of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. More precisely, the FIRST law defines the force QUALITATIVELY, the second law offers a quantitative measure of the force, and the third asserts that a single isolated force doesn't exist. These three laws have been expressed in several ways, over nearly three centuries,[a] and can be summarised as follows: First law In an inertial frame of reference, an object either remains at rest or continues to move at a constant VELOCITY, unless acted upon by a force.[2][3] Second law In an inertial frame of reference, the vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma. (It is assumed here that the mass m is constant – see below.) Third law When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body. The three laws of motion were first compiled by Isaac Newton in his Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687.[4] Newton used them to explain and investigate the motion of many physical objects and systems.[5] For example, in the third volume of the text, Newton showed that these laws of motion, combined with his law of universal gravitation, explained Kepler's laws of planetary motion.

nical force can be defined as a force that ACTS between the two OBJECTS (one applying the force and another which is in a state of rest or in a state of MOTION) that are in direct contact RESULTS change in the state of the object (state of rest or state of motion).

This is because goitre is caused DUE to the deficiency of iodine in the DIET and people living in coastal areas mainly feed on SEA FOODS which CONTAIN sufficient amount of iodine. So, they usually not suffer from goitre.

299,792 kilometers PER secondThe speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory NOTHING can travel faster than light. In miles per hour, light speed is, WELL, a LOT: about 670,616,629 mph. If you COULD travel at the speed of light, you could go around the Earth 7.5 times in one second.
