well igneous rock and metamorphic rock
If magnification is less than one it means the image is the same exact size as the object.
The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.
Answer:
15186 J energy lost due to friction
Explanation:
Given:
- Height of the tallest hill (first) h_1 = 16 m
- Height of the last hill h_2 = 7 m
- Velocity @tallest hill = 0
- Velocity @last hill = 0
Find:
How much energy was lost due to friction can be determined from an energy balance at point on top of tallest hill and on top of last hill:
E_p,1 + E_k,1 = E_p,2 + E_k,2 + E_f
Where, E_k,1 = E_k,2 = 0
E_p,1 - E_p,2 = E_f
E_f = m*g*(h_1 - h_2)
E_f = 172*9.81*(16 - 7)
E_f = 15186 J
