I don’t know how air would be an insulator so I’m guessing that one isn’t
Gravitational Potential Energy = mgh.
Where m = mass in kg.
g = acceleration due to gravity = 9.81 m/s2.
h = height in metres.
PE is in Joules
Potential Energy = 20 * 9.81*100 = 19620 J
Answer:Metaloids have properties of both metals and non-metals.
Explanation:
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.
