The earliest known telescope was created in the netherlands in the early 17th century. it would have been most in a) confirming newton's "laws of motion." b) proving galileo's heliocentric theory. c) studying william harvey's theory of the circulatory system. d) validating sir francis bacon's belief in the "scientific method." eliminate

B) proving Galileo's heliocentric theory.

Explanation:

This is the theory that would have benefitted the most from the use of the telescope. Galileo's theory stated that the body at the center of the solar system is the sun, not the Earth. This can be observed with the use of a telescope. On the other hand, the theories of Bacon and Newton do not require a telescope to be proven, while Harvey's theory would need a microscope, not a telescope.

the assassination of president lincoln was just one part of a larger plot to decapitate the federal government of the u.s. after the civil war. the first reaction to lincoln’s death was disbelief. then it quickly changed to grief. abraham lincoln’s death created an outpouring of grief from citizens in both the north and the south.

explanation:

lincoln was the first u.s. president to be assassinated. president abraham lincoln, america’s civil war leader, was assassinated just five days after confederate general robert e. lee surrendered his army at appomattox court house, ending the four-year war between the states. on the evening of april 14, 1865, lincoln was attending a performance of our american cousin at ford’s theatre in washington, d.c. john wilkes booth – a 26-year old actor, confederate sympathizer, and white supremacist – slipped into the presidential box and shot lincoln in the head. john wilkes booth and his conspirators had initially planned to kidnap lincoln to save the confederate states. but as the confederacy faltered, booth’s thoughts turned to murder. booth may have decided to act on his hatred after lincoln endorsed giving the right to vote to african-american men who had served in the union army.
