Question

a comet is expected to pass by the earth. francis wants to see as much detail of the event as he can. which technology allows him to view the comet? a rover a scanning electron microscope a scanning tunneling microscope a telescope

Explanation:

A telescope is an optical instrument that makes distant objects appear nearer. It is designed to view celestial objects like comets from Earth. A rover is used for exploring surfaces (e.g., Mars rover). A scanning electron microscope is used for magnifying very small specimens (e.g., cells, materials at a microscopic level). A scanning tunneling microscope is used for imaging surfaces at the atomic level. Since Francis wants to view a comet (a celestial object), a telescope is the appropriate technology.

Answer:

a telescope
