Text Solution. Solution : (i) The ratio of increase in length of the length of the body per degree rise in temperature is called ‘Coefficient of linear expansion’. (ii) Its SI unit is per kelvin. `(DeltaL)/(L_(0)) = alpha_(L)DeltaT implies alpha_(L) = (DeltaL)/(DeltaT. What is coefficient of linear expansion write its formula? Coefficient of linear expansion … Read more
Wetting is the ability of a liquid to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together. This happens in presence of a gaseous phase or another liquid phase not miscible with the first one. What is wetting and detergency? ‘ As a component of growing media, wetting … Read more
The y-intercept formula is used to find the y-intercept of a function. i.e., it is used to find the point where the graph of the function cuts the x-axis. The formula to find y-intercept says that the y-intercept of a function y = f(x) is substituting x = 0 in it and solving for y. … Read more
What is the definition of instantaneous angular acceleration? Instantaneous angular acceleration, abbreviated as αi (Greek symbol alpha), is the rate an object rotates in a circular path at a particular moment in time. Like instantaneous acceleration, the angular acceleration formula requires knowning the rate of change in the velocity. What do you mean by instantaneous … Read more
A lever is a simple machine with a fulcrum and a solid beam. On each end of the beam, the effort (input force) and load (output force) are applied. The fulcrum is considered the pivot point of the beam. A load is applied to the other end of the lever when an effort is applied … Read more
Total internal reflection (TIR) is the phenomenon that involves the reflection of all the incident light off the boundary. What is total internal reflection easy definition? total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The … Read more
We know that angular frequency is the radian of the angle through which the body moves per unit time. Thus we can write angular frequency as, ω =2π /T, where ω is the angular frequency. The SI unit of angular frequency in radian per second. What is angular frequency called? In physics, angular frequency “ω” … Read more
Viscosity = (2 x (ball density – liquid density) x g x a^2) ÷ (9 x v), where g = acceleration due to gravity = 9.8 m/s^2, a = radius of ball bearing, and v = velocity of ball bearing through liquid. Plug your measurements into the equation to calculate the viscosity of the liquid. … Read more
Oscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples of oscillation include a swinging pendulum and alternating current. What is oscillation definition in physics? Oscillation is defined as the process of repeating variations … Read more
General relativity is committed to claims regarding which motions are and are not possible for a single particle entirely alone in the universe, and it also allows for the existence of universes whose total angular momentum is other than zero. What is relativity in physics definition? Relativity is a theorem formulated by Albert Einstein, which … Read more
