they claimed that without slaves the economy would collapse I think, I'm not quite sure if I'm remembering correctly though
The force driving behind European Imperialism in Africa was when the Europeans took advantage of advances in technology to enhance their ability to acquire resources from Africa.
The correct answer is Sir Ernest Rutherford.
One of the first findings on atomic energy theory was reached in 1911 by Rutherford, who became known as the father of nuclear physics.
He discovered that the mass of the atom was concentrated in its nucleus, and proposed that the nucleus has a positive charge and is surrounded by negatively charged electrons, which had been discovered in 1897 by J. J. Thomson.
His theory was complemented in 1913 by Niels Bohr, who placed the electrons in definite shells or quantum levels.
Newton's second law is that every object will move in a straight line and in one direction unless acted on by an outside force.
Hope this helps!
The correct answer to this open question is the following.
What caused West Africans to transition from controlling the exchange of goods to European slave raiders was the fact that European powers such as Great Britain, Spain, or Portugal directly competed to acquire the control of the slave trade of African people.
Everything started with John Hawkins, considered to be the first European slave trader in 1562. Years later the government of Englan granted charters to merchants and traders to open locations in West Africa where they could exploit the raw materials and natural resources such as ivory and gold. Because of this, England started to get more competition from other European nations such as Switzerland, the Dutch, and Denmark.
