Not unless somebody is holding it down.
If the rock weighs 10N and you just set it in the water, it'll sink until it displaces
10N of water, and at that point, it has no desire to sink any further.

The rock will float in water. Archimedes' principle states that an object will float if it displaces more fluid (in this case water) than its own weight. In this case, the rock displaces 12N of water, which is greater than its own weight of 10N, so it will float.
The net force is the difference between the two forces. In this case, the net force is 20N (left force) - 10N (right force) = 10N to the left.
The impulse of a force is the product of the force and the time it is applied. In this case, the impulse is 10N * 5s = 50Ns.
The 10N object has the same mass whether on the moon or on Earth. Mass is an intrinsic property of an object that does not change with location. However, the weight of the object would be lower on the moon due to the moon's weaker gravity compared to Earth.
If the stone weighs 10N, then a force of at least 10N must be applied in the opposite direction to prevent it from falling. This is because the force of gravity pulling it downward is balanced by an equal and opposite force applied upward.
The work done to move a 10N book 5 meters can be calculated using the formula: Work = Force x Distance. Therefore, the work done would be 10N x 5m = 50 Joules. This means that 50 Joules of energy was expended to move the book over the specified distance.
