step 1 Question number 24, the real weight is equal to 5 newtons. So the mass of the object is 0 .509 k

The gravitational force exerted on a solid object is 5.00 N...

The gravitational force exerted on a solid object is $5.00 \mathrm{N}$ When the object is suspended from a spring scale and submerged in water, the scale reads $3.50 \mathrm{N} \text { (Fig. } \mathrm{P} 15.24)$
Find the density of the object.

Key Concepts

Density

Density is a measure of mass per unit volume of a substance and is used to characterize how compact the mass in an object is packed. It is defined by the equation density = mass/volume. In the context of submersion in a fluid, comparing the densities of the object and the fluid helps predict whether the object will sink or float and is key to deriving unknown properties like the object's density from its submerged weight.

Archimedes’ Principle

Archimedes’ Principle states that any object partially or fully immersed in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the object. This principle is essential for determining the difference between the actual weight of an object and its apparent weight when submerged.

Gravitational Force

Gravitational force is the force of attraction between the Earth and an object, acting downwards, which gives the object its weight. It is calculated as the product of mass and gravitational acceleration and plays a crucial role in determining the behavior of objects both in air and when submerged in a fluid.

Buoyant Force

Buoyant force is the upward force exerted by a fluid on a submerged or partially submerged object. This force is equal in magnitude to the weight of the fluid displaced by the object, and it effectively reduces the net force (apparent weight) acting on the object when it is in the fluid.
