the density of gold is 19.3 g/cm3. suppose a certain gold wedding ring deplaced 0.55mL of liquid when dropped in a glass of spar
adell [148]

Answer:

19.3

Explanation:

Assuming we have to find Specific gravity of gold.

As we know that specific gravity is defined as the ratio of weight of the object and weight of the water displaced by the object

so it is given by

specific gravity = weight of the object/weight of the water displaced

now we have

weight of the object = (density)(volume)g

weight of object = (19.3)(0.55)g

now weight of the liquid displaced is given by

weight of water displaced = (1 g/cm^3)(0.55ml)g

now we have

specific gravity = (19.3×0.55)/(1×0.55)

specific gravity= 19.3

leva [86]

Answer:

Charge

Explanation:

Charge is a fundamental property of all matter. All matter has electrical and magnetic properties because the atoms that make up matter are held together by electromagnetic forces.

These charges are usually positive and negative charges. When these charges which make up an atom (positive and negative) are equal, the atom is said to be electrically neutral. When positive charge is greater than negative charge, the atom is said to positively charged. Also, if the number of negative charges are more in an atom, the atom is said to be negatively charged.
