Xrays with a wavelength of 0.070 nm diffract from a crystal. two adjacent angles of x-ray diffraction are 45.6 and 21.0 what is the distance between the atomic planes responsible for the diffraction?

e) none of the above answers are correct

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

conservation of mass

mass before something happens = mass afterwards
