PLEASE HELP It has been estimated that in this way the world's seagrass meadows
can capture up to 83 million metric tonnes of carbon each year. While
seagrasses occupy only 0.1% of the total ocean floor, they are estimated
to be responsible for up to 11% of the organic carbon buried in the ocean.
Calculate the total annual amount of carbon captured by the World Ocean.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
