Why is gravity taken as 10 m/s^2 while gravity is changing at some places like equator where gravity is less?

Weight depends on change in gravity while mass is a constant. so our weight decreases when we r at high altitudes. so it is is clear from this that gravity is changing . so how do people accept...

How can I find out whether a synthesised material is nano or not?

The XRD results show the size of the particle is 5 nm. But TEM results show that the particle size range from 5-100 nm. How can I sure that the material is nano?
