Which method is used for an oil spill out at sea to break the oil into small droplets? a, burning b, booming c, dispersion d, skimming

C.Dispersion

Explanation:

Dispersion is the method in which mixtures of emulsifiers and solvents known as dispersants are used to break the oil into smaller particles for the purpose of cleaning the oil spill.

Since the particles are broken down into smaller droplets they get easily dispersed in the water body and then their biodegradation by microbes takes place which allows for the cleanup.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
