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:
The answer to this question is the letter "B" which is "This is an example of sculpture series". This is not true.
The attached picture which is a portrait of a sculpture is made of sand and it is found in New Mexico.
Earlier in the 1700s, the French & Indian war happened in which Great Britain was involved in. They made taxes so they could pay all of their soldiers for fighting in the war.
Yes that is true. It was President James K. Polk. Hopefully that answers your question.
Answer: The United States Tax Court (in case citations, T.C.) is a federal trial court of record established by Congress under Article I of the U.S. Constitution, section 8 of which provides (in part) that the Congress has the power to "constitute Tribunals inferior to the supreme Court".[1] The Tax Court specializes in adjudicating disputes over federal income tax, generally prior to the time at which formal tax assessments are made by the Internal Revenue Service
