The answer is A, it’s a sound wave
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

Answer:
a) The velocity of rock at 1 second, v = 9.8 m/s
b) The velocity of rock at 3 second, v = 29.4 m/s
c) The velocity of rock at 5.5 second, v = 53.9 m/s
Explanation:
Given data,
The rock is dropped from a bridge.
The initial velocity of the rock, u = 0
a) The velocity of rock at 1 second,
Using the first equation of motion
v = u + gt
v = 0 + 9.8 x 1
v = 9.8 m/s
b) The velocity of rock at 3 second,
v = u + gt
v = 0 + 9.8 x 3
v = 29.4 m/s
c) The velocity of rock at 5.5 second,
v = u + gt
v = 0 + 9.8 x 5.5
v = 53.9 m/s
D) Kilograms is the standard unit of mass
