‘Physics’ comes from a ............... word meaning nature
The word 'Physics' is derived from the Greek word 'physikē,' meaning nature. The term was used by ancient Greek philosophers to describe the study of nature and natural phenomena.
The scope for ratio of length is in order to ...............
The range of time scale is about
The range of time scales in physics and cosmology can span from extremely small fractions of a second, such as those involved in particle physics, to extremely long durations, such as the age of the universe. The given range $10^{-22}$ seconds to $10^{18}$ seconds covers this broad spectrum, from the smallest measurable quantities to timescales associated with cosmic events.
Birth, evolution and death of stars etc. are studied in branch of physics known as
Astrophysics is the branch of physics that deals with the study of the birth, evolution, and death of stars, as well as other celestial phenomena. It combines the principles of physics and astronomy to understand how the universe behaves on a large scale. NEET students should remember that 'Astro' refers to stars or celestial objects, making 'Astrophysics' the correct answer.
............... is a branch of physics in which heat engine and refrigeratior efficiency is studied
Thermodynamics is the branch of physics that deals with the study of heat and temperature and their relation to energy and work. This includes the efficiency of heat engines and refrigerators. NEET students should remember that 'Thermo' relates to heat, making 'Thermodynamics' the correct answer.
What is full name of LHC
The full name of LHC is the Large Hadron Collider. It is the world's largest and highest-energy particle collider, located at CERN. It is used to study particle physics by colliding hadrons, such as protons, at very high speeds. NEET students should remember that 'Hadron' refers to the particles being collided in this context, making 'Large Hadron Collider' the correct answer.
The range of mass varies from ...............
Length of Galaxies is in order of ...............
The length of galaxies is typically in the order of $10^{21} m$ to $10^{25} m$. Therefore, the closest option is $10^{26} m$.
The approximate value of charge of an electron is ...............
The charge of an electron is approximately $1.6 imes 10^{-19} C$. Hence, the correct value is $10^{-19} C$.
. Space is homogeneous and isotropic so ............... law of servation is the result of this
The homogeneity and isotropy of space imply that physical laws do not change from one point to another (homogeneity) and are the same in every direction (isotropy). This results in the conservation of linear momentum (due to homogeneity) and angular momentum (due to isotropy).
