Answer: Scanning Tunneling Microscope
Explanation:
The answer is, of course, the greatest Star Trek fan art imaginable: images literally built out of individual atoms. The images are the work of IBM scientists who created the unique artwork with a two-ton machine called the Scanning Tunneling Microscope that moves single atoms across a tiny piece of copper.
Answer:
the potential energy a massive object has in relation to another massive object due to gravity
E=mgh. 196=5kg*9.81m/s^2*h. So h=196/(5*9.81)=4m
Usually
pH scale measures from 1 to 14
Purple colour indicates pH as 14
Hence it's an base
But it doesn't react with metals to form salts and hydrogen gas.
It's sure it's non metal but not base
One possibility is that it's Carbon compound or Graphite compound which reacts like base but a metal in real sometimes
