When an object is underwater, the sound it produces is louder compared to when it is in the air. This is because sound travels faster and more efficiently in water than in air, resulting in a louder sound underwater.
The change in position of one object compared to another object is called relative motion. This describes the movement of one object relative to the other, taking into account their positions and velocities.
The change in size of an image compared with the size of an object is termed magnification. This can be calculated as the ratio of the size of the image to the size of the object. Magnification can be expressed as magnification = image size / object size.
Actually, a change in the position of an object when compared to a reference point is defined as displacement. Speed, on the other hand, is the rate at which an object covers distance over a period of time.
Displacement is the term used to describe the change in position of an object when compared to a reference point. It is a vector quantity that includes both the distance and the direction of the movement.
A change in an object's position compared to fixed objects around it is called displacement. Displacement measures the overall change in position from the starting point to the ending point, taking into account both distance and direction of movement.
The change in position of an object compared to a reference point(another object) is called motion.
The change in position of one object compared to another object is called relative motion. This describes the movement of one object relative to the other, taking into account their positions and velocities.
The change in size of an image compared with the size of an object is termed magnification. This can be calculated as the ratio of the size of the image to the size of the object. Magnification can be expressed as magnification = image size / object size.
The answer is relative motion.

When its position changes with respect to a point of reference.
A change in an object's position compared to fixed objects around it is called displacement. Displacement measures the overall change in position from the starting point to the ending point, taking into account both distance and direction of movement.
There is a force called upthrust coming from the water. this pushes objects upwards, making the resultant force lower, which means they seem to weigh less.
A change in mass can affect an object's motion by altering its inertia. An object with a larger mass will require more force to accelerate or decelerate compared to an object with a smaller mass. As a result, a change in mass can impact an object's speed, acceleration, and overall movement.

It's true that the volume of displaced water of a floating object equalst the portion of that object that is underwater.
