What is the theory of relativity |
| Answer» Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating 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 20th-century 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. | |

What type of force does a protoms exerts on a protons |
| Answer» 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 force | |

Define radius of gyration |
| Answer» Radius of gyration or gyradius refers to distribution of the components of an object around an axis. In terms of [mass moment of inertia], it is the perpendicular distance from the axis of rotation to a point mass (of mass, m) that gives an equivalent inertia to the original object(s) (of mass, m). The nature of the object does not affect the concept, which applies equally to a surface, a bulk mass, or an ensemble of points.Mathematically the radius of gyration is the root mean square distance of the object\'s parts from either its center of mass or a given axis, depending on the relevant application.It is actually the perpendicular distance from point mass to the axis of rotation. | |

Why moon has no atmosphere |
|
Answer» Yes its the best and the right answer Moon has no atmosphere because the value of acceleration due to gravity \'g\' on the surface of moon is small. Therefore, the value of escape velocity on the surface of moon is small. That is why all the molecules of gases escaped and there is no atmosphere on moon. |
