Describe the location of the Tang and Song Dynasties relative to two oceans.

China

Explanation:

The Song dynasty (960-1279) follows the Tang (618-906) and the two together constitute what is often called "China's Golden Age." The use of paper money, the introduction of tea drinking, and the inventions of gunpowder, the compass, and printing all occur under the Song. (The fact that the dynasty spans the year 1000 may make it easier for students to locate these developments in time.)

While short-lived, the Sui Dynasty  built a strong foundation for the great achievements of the next dynasty, the Tang (tahng). The Tang Dynasty ruled for nearly 300 years (618–907). The Tang  emperor who began these achievements was Tang Taizong. His brilliant reign lasted from 626 to 649.

we can solve this via the kinematic equation:

where the vertical velocity is zero and so:

since the height of the building is 29.3 meters then:

the ball was in motion for approximately 2.45 seconds
