One of the main cause of ocean current to occur is variation of temperature of different layer of oceanic water.Water which have high temprature is less dense and this Less density water float above the surface of high density water. When this less density water reached on the surface of ocean that time wind which blows on the surface water makes the water cool or in other words we can say that water released its heat to the surrounding environment. when water becomes cool it again shifted in downward direction and less density water will moves upward. In this way this process will continue and hence ocean current is created.
Alright, to begin with. The unit of Force is in Newtons. Meaning the first two options are out of the answers. Now in order to find the force. You will need to take the mass and multiply that by the acceleration. Which will give you 26.75 Newtons.
