Answer:
9
Explanation:
If you add 9+4=13 then you subtract 4 to 13 you get 9. If there is 9 apples and you eat 4 then you get 5 but in this case is 9.
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 years between 1912 and 1938 were filled with upheaval in China. It was marked by the driving out of many of the foreign people there because it was believed they were a bad influence.
The Japanese were still in the beginning of the Sino-Japanese War in 1938, and they had recently taken the KMT (The Chinese Nationalist Government is the KMT) capitol of Nanking as well as Shanghai. At this point, the Japanese were making quick work of the Chinese army with their highly industrialized military and basically un-opposed air superiority. Japan also had a puppet regime in Manchukuo (formerly and currently known as Manchuria, the Northern section of China) and had established the deposed Qing Dynasty emperor, Puyi, as their token ruler.
<span>During this time, Japan ratified a puppet regime in the Northern section of China known as Manchuria. The Japanese elected Puyi, the dethroned Emperor of the Qing Dynasty, as their leader.</span>

Most military people I have known believe the US Air Force is the safest branch to be in from a combat perspective. In the Army and Marines, the enlisted men do the vast majority of fighting, and, therefore, getting killed.
In the Spanish colonies in America the colonists created a kind of caste system based on ethnic hierarchy which of course put the Spaniards on top. The rest of ethnic groups ranked based on their resemblance of the Spaniards so for example the Indians would be ranked higher than Blacks as they more resembled the Spaniards.
