Answer:A pendulum illustrates the conservation of energy. The pendulum has the most potential energy - the energy of position or stored energy - when it is highest above the ground. It has the most kinetic energy - the energy of motion - when it is moving the fastest. As the pendulum swings downward, the potential energy changes to kinetic energy. As it swings upward, the kinetic energy changes to potential energy. The back-and-forth swinging of a pendulum is simple harmonic motion - motion that repeats periodically. The period of a pendulum is the time needed for one complete swing back and forth. This period is constant; it changes only if the length of the pendulum is changed. Ask student to time the periods of their pendulums when the pendulums swing through a longer distance (larger arc) or shorter distance (smaller arc). They will discover that the periods are the same. Have the students then change the mass by adding one or more washer to their pendulum. When the students time the periods, they discover that the period does not change if the mass is changed. Ask students to experiment to find what will change the period of the pendulum. Students will discover that the period will change if the pendulum’s length is changed.
Explanation:
<span>This diversity caused what has become to be known as "cultural imperialism". In other words, the culture of the colonizer was reflected in both the colony and the indigenous people that they came into contact with. This led to the expansion of the ideas of individual countries as well as colonies as diverse as Europe.</span>
The answer is C. There was concern that U.S. citizens' privacy was being violated.

I just took the test, lol!!
Answer:
<u>The main reason was the dispute over the lands of the Native tribes. </u>
Explanation:
The governments of several states of the United States felt that the presence of the tribes was a threat to peace and security, because many Native Americans had fought against the United States in previous wars, often armed by foreign nations such as Great Britain and Spain. Other white settlers and land speculators simply wanted the land that was being occupied by the tribes. Therefore, these governments wanted all tribal lands within their borders to be placed under state jurisdiction.
