Answer: The object will float.
Explanation:
Balanced force is defined as the force that gets cancelled out when equal forces are acting in the opposite direction. The net force on the system comes out to be 0.
Unbalanced force is defined as the force that does not get cancelled out because unequal forces act on the system in opposite direction. The motion of the object is in the direction of net force.
According to the question:
Object is exerting a downward force of 10 N on the water and water is exerting an upward force of 12 N on water.
As, the upward force by water is more than the downward force by object. So, the object will float on the surface of water.
If the downward force by the object is been more than the upward force, the object will sink.
Hence, the object will float.
Temperature dependency is responsible for the process that hot water freeze faster than cold water.
The effect given above is called Mpemba Effect. According to this idea hot water freezes more quickly as compared to cold water. But until now there is no convincing explanation for this strange phenomenon. One idea is that hot containers make better thermal contact with a refrigerator and so conduct heat more efficiently because a good conductor is good fro the transfer of heat. Another idea about this effect is that warm water evaporates more quickly and since this is an endothermic process, it cools the water making it freeze more quickly.
warm water evaporates rapidly and since this is an endothermic process, it cools the water making it freeze more quickly.
