Question

11
A copper wire 0.5 mm in diameter
and 2 m in length supports a mass of
3 kg. It is stretched by 2.38 mm.
Calculate Y.​

Answer 1

Answer:

In physics, the Planck length, denoted ℓP, is a unit of length. It is also the reduced Compton wavelength of a particle with Planck mass. It is equal to 1.616255(18)×10−35 m. It is a base unit in the system of Planck units, developed by physicist Max Planck. The Planck length can be defined from three fundamental physical constants: the speed of light in vacuum, the Planck constant, and the gravitational constant.
