one starts at igneous rock and goes through metamorphism and becomes a metamorphic rock.
another is a sedimentary rock goes through melting and becomes magma
Solution :
Acceleration due to gravity of the earth, g
Acceleration due to gravity at 1000 km depths is :
= 8.23 m/s
Acceleration due to gravity at 2000 km depths is :
= 6.73 m/s
Acceleration due to gravity at 3000 km depths is :
= 5.18 m/s
Acceleration due to gravity at 4000 km depths is :
= 3.64 m/s
Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly through a medium. Sound travels faster in warmer temperatures than cooler and more slowly in cooler temperatures.
Answer:
5 m/s
Explanation:
Assuming no air resistance, the horizontal acceleration is 0 m/s². So the final velocity is the same as the initial velocity.
Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth. The standard atmosphere is a unit of pressure defined as 101,325 Pa, which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.
