7 0

Explanation:

1) velocity = displacement/time

time = displacement/velocity

time = 200/660

= 10/33

= 0.303

2) vf = vi - a*t

0 = 30 - 9.8*t

t = 30 ÷ 9.8

t = 3.06 seconds

Can some one give me a conclusion for natural resources
levacccp [35]

Answer:

The exploitation of high-value natural resources—oil, gas, minerals, and timber—has often been a key factor in triggering, escalating, or sustaining violent conflicts around the globe. Competition over renewable resources such as land and water is on the rise, and environmental degradation, population growth, and climate change are compounding the challenges. Governments are therefore under increasing pressure to sustainably manage natural resources and resolve conflicts around their ownership, management, allocation, and control.
