Question

multiple select question select all that apply which statements about the sixth quark are true? it took several years and an international team of nearly 450 scientists to find the sixth quark. scientists were surprised when they found evidence for the sixth quark. scientists discovered five quarks and hypothesized that a sixth quark existed. the sixth quark was hard to detect because only about one - billionth of a percent of the proton collisions performed showed its presence.

Explanation:

Quarks are fundamental particles in physics. The discovery of the sixth quark was a major scientific endeavor. It took significant time and a large - scale international effort to find it. Its low - probability appearance in proton collisions made it hard to detect. Scientists had discovered other quarks first and hypothesized the existence of the sixth one. There's no information suggesting surprise upon discovery.

Answer:

It took several years and an international team of nearly 450 scientists to find the sixth quark.
Scientists discovered five quarks and hypothesized that a sixth quark existed.
The sixth quark was hard to detect because only about one - billionth of a percent of the proton collisions performed showed its presence.
