Answer:
12.25m/s
Explanation:
Since the initial velocity of the dropped rock is 0, you can write this as:
Now, you can set up the equation for the thrown rock:
Hope this helps!
C) accretionary-wedge complex.
Explanation:
The accretionary wedge complex is a thick accumulation of sediments and small tectonic blocks formed from materials scraped off subducting oceanic lithosphere at a convergent margin.
Space between the subducting plate and the less dense plate gets filled by sediments scraped off the subducting plate and this forms a wedge like sediment called the accretionary wedge.
- The accretionary wedge is invariably made up of materials found on the ocean floor.
- Under extreme conditions, some parts of wedge transforms into metamorphic rocks.
- The wedge is made up of: pelagic sediments, ocean floor basalts e.t.c

4 main components are: Nitrogen, Oxygen, Argon and water vapour
Answer:
3.95 m
Explanation:
m = 1 kg, h = 100 m, k = 125 N/m
Let the spring is compressed by y.
Use the conservation of energy
potential energy of the mass is equal to the energy stored in the spring
m x g x h = 1/2 x ky^2
1 x 9.8 x 100 = 0.5 x 125 x y^2
y^2 = 15.68
y = 3.95 m
