Explain the range of functions of physics in terms of length, mass and time.

Text Solution

Verified by Experts

`to` Length: At one end, it studies phenomena at the very small scale of length (`10^(-14)` m or even less) involving electrons, protons, etc., at the other end it deals with astronomical phenomena at the scale of galaxies or even the entire universe whose extent is of the order of `10^(26)` m. The two length scales differ by a factor `10^(40)` or even more.
`to` Mass : The range of masses goes from say `10^(-30)` kg (mass of an electron) to `10^(55)` kg (mass of known observable universe). Terrestrial phenomena lie somewhere in the middle of this range.
`to` Time : The range of time scales can be obtained by dividing the length scales by the speed of light `10^(-22)` s to `10^(18)` s.
