The correct answer is A. buoyancy, gravity.<\/p>\n
Buoyancy is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. All objects experience two forces when they are in a fluid: gravity and buoyancy. Gravity pulls the object down, while buoyancy pushes the object up. If the object is more dense than the fluid, then gravity will be stronger than buoyancy and the object will sink. If the object is less dense than the fluid, then buoyancy will be stronger than gravity and the object will float.<\/p>\n
Pressure is a force per unit area. It is caused by the weight of the fluid above the object. The pressure increases with depth, so the bottom of the object experiences more pressure than the top of the object. This pressure difference can cause the object to deform, but it does not affect whether the object floats or sinks.<\/p>\n
Inertia is the tendency of an object to resist changes in its motion. An object with more inertia will be more difficult to accelerate or decelerate. The inertia of an object does not affect whether the object floats or sinks.<\/p>\n
Therefore, the two important forces for a floating body are buoyancy and gravity.<\/p>\n","protected":false},"excerpt":{"rendered":"
