Ernest Rutherford contributed to the atomic theory by discovering that the atom is mostly empty space.
He can to that conclusion because he fired alpha particles at gold foil, which was so thin that it was only around .00004 cm thick, and while almost all shot straight through, some actually bounced back!
He likened it to shooting a 15-inch round(bullet) at tissue paper, only to have it bounce right back at you! Based on this, he theorized that the atom is mostly empty, which is why a majority of the particles passed right through, but in the very center of the atom there is a super-dense structure called a nucleus that held a majority of the atom's mass. This super-dense mass would be more than massive enough to deflect the particle, should they collide.
McCulloch v. Maryland (1819) is one of the first and most important Supreme Court cases on federal power. In this case, the Supreme Court held that Congress has implied powers derived from those listed in Article I, Section 8. The “Necessary and Proper” Clause gave Congress the power to establish a national bank.
The league of Nations, I believe.
The correct answer is A. It increased the number of enslaved laborers forced to grow crops that were exported from the Americas to Europe.
Explanation:
The Atlantic slave trade implied hundreds of Africans were forcibly taken to American and forced to work as slaves. This practiced was related to the triangular trade, in which, products such as cotton and tobacco were exported to Europe, then manufactured goods were taken to Africa, and slaves were exported to America.
Moreover, due to the need for America to produce raw goods such as cotton or tobacco to contribute to the triangular trade, most of the slaves from Africa were used in plantations. Thus, the Atlantic trade impacted the role of America in the triangular trade because "it increased the number of enslaved laborers forced to grow crops that were exported from the Americas to Europe".
