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...

What is the best substrate for exfoliating few layers of hexagonal boron nitride (hBN) using traditional scotch tape method?

Unlike graphene, it is usually very difficult to exfoliate few layers (~10 nm thick) of hBN on SiO2 substrate due to lip-lip interaction at the edges. Au substrates have been proven very useful...
