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.

Answer:
President Roosevelt's main wish to accomplish was to increase employment for the poor.
Explanation:
While Roosevelt's main goal was to increase employment, he also recognized the need for a support system for the poor. The Federal Emergency Relief Administration, started in 1933, addressed the urgent needs of the poor.
To have her opinions heard in the party. He states: <span>"for the first time where the women stood when it came to a national convention. I shortly discovered that they were of little importance. They stood outside the door of all important meetings and waited." Only men's voices were given space and time at the National Convention.</span>
The Correct Answer Is:
Once India gone, they lost a major source of revenue using which they were using to rule the other colonies. Moreover, India's freedom acted like a catalyst for them to demand freedom. Pretty soon the British had to lose the colonies too, reducing the once mighty kingdom to a humble island.
Probably the most sustained effect was the way India earned freedom - lead by Gandhi and other leaders. It showed the world that a war could be fought spiritually also, without violence. It inspired the leaders elsewhere in the world, most probably Martin Luthar King and Nelson Mandela being the most prominent.
