Answer:
Things he did
Explanation:
The Geometric Compass
Galileo's Thermoscope
Pendulum Clock
The First Microscopes
Some of Galileo's other inventions include: a magnification device that made telescopes twenty times more powerful; a one-horsepower pump to raise water; an oar placement design for a ship's galley in which the oar acted as a lever against the water, which behaved as a fulcrum; and a design for an accurate hydrostatic balance for weighing things in air and water.
The Lewis and Clark expedition, also known as the Corps of Discovery, started its lengthy journey to explore the lands of the Louisiana Purchase in search of a river route across the West to the Pacific Ocean in May 1804. They travelled up the Missouri River all the way to the village of St. Charles. The men received no more supplies or reinforcements after they passed that village. During the summer of 1804, after travelling for more than 600 miles, the Corps of Discovery finally met some Native Americans who helped them and provided them with fresh fruits and vegetables. They also provided them with horses and a guide to lead them across the Rocky Mountains.
The expedition finally reached the Pacific Ocean in November 1805. Since they had not found a river route to the Pacific, they headed back home in March 1806. The Pike Expedition was established when an army officer, Zebulon Pike, was sent on a mission to find the starting point of the Red River, which was important because it was considered the western border of the Louisiana Territory with New Spain. Pike started out by heading into the Rocky Mountains, aka Colorado, and then tried to reach the apex of the mountain now called ‘Pike’s Peak’. He travelled in Spanish lands in 1807, until he was arrested by the Spanish, who thought he was a spy. Later, when he was released, he went back to the United States and recounted his trip. Even though he was imprisoned, he was pleased to do business with the Spanish. Pike’s expedition gave many Americans an insight into the Southwest. However, if the 2 expeditions are to be compared, the Lewis and Clark Expedition was definitely more successful because although they did not find a continuous waterway to the Pacific Ocean, they located an Indian trail that led from the upper end of the Missouri River to the Columbia River which ran to the Pacific Ocean.
Answer:
The correct option is B
Explanation:
The creation of visual imagery and perception are said to use almost the same neural machinery. Thus, it can be said that imagery and perception are totally based on same neural representation. When the participants were creating images, there was overlapping activities in the brain between visual imagery and perceptions, thus all non-visual sensation at that point would be deactivated.
Answer:
random assignment
Explanation:
Random assignment is an experimental technique that seeks to form random and fully randomized experimental groups in relation to the treatments presented in the research. This type of technique prevents the formation of "combined groups" that show the differences to each other and can generate a comprehensive result on the research, thus the random formation of diverse groups that can represent a much larger and different population.
An example of this can be seen in the question above, where the researcher decides the formation of the group that will receive the medicine and the group that will receive the placebo, completely randomly.
