Which is the best example of a scientific discovery resulting from new technology? the discovery that elements can be grouped in a table on the basis of their properties
the discovery of atomic structure which led to the development of an electron microscope
the discovery of the structure of DNA, which occurred as the result of an X-ray image of a DNA molecule
the discovery that plant pigments can be separated and identified by using paper and a solvent

third

Explanation:

i think so because finding structure of dna can help a lot for well being of human being

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
