Yes. You can cut a coin in half with real laser. or a good pair of tin shears (special scissors made for cutting metal)
Can pure silver be cut with a knife?
No... Unless you have a saw capable of cutting metal dont try. Sodium Metal can be cut with a knife though and looks similar to silver, and also produces an exothermic reaction when it comes into contact with water. In other words... Goes BOOM.
Why does Neptune has eleven satellites even when no one is there?
A natural body that rotates around a planet is a satellite, as in a moon. Man made satellites (artificial satellites) are made mostly of metal and rotate around earth looking at weather patterns or orbiting other planets for information. When they say Neptune has eleven satellites, they mean moons orbiting the planet, not man made ones. There doesn't have to be anyone there for there to be satellites of both kinds there.
