Question

For an object that floats in a liquid, which of the following statements is true? Group of answer choices The specific gravity of the object is greater than or equal to the specific gravity of the liquid. The mass of the object is equal to the mass of liquid displaced.

Answer 1

Step-by-step explanation:

Object is Floating in a liquid

weight of object is equal to weight of displaced fluid

i.e.

`\rho _oVg=\rho _mV'g`

i.e.
`\rho _oV=mass\ of\ object`

`\rho _mV'=mass\ of\ liquid\ displaced`

where V and V' is the volume of object and volume of object inside the liquid.

therefore mass of liquid displaced must be equal to mass of object
