PLEASE HELLPP ILL GIVE how are currents created?

A ) Warm and Cold water mixing together into one
B ) Wind moves across the surface of the water
C ) Fish swim fast enough to cause drag in the water
D ) Warm water moves around ice caps

B ( I think so?)

Explanation:

Ocean currents are driven by wind, water density differences, and tides. Oceanic currents describe the movement of water from one location to another.

Coastal currents are intricately tied to winds, waves, and land formations. Winds that blow along the shoreline—longshore winds—affect waves and, therefore, currents.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
