What is the density of a 700 kg object with a volume of 649 m3? (density: d = ) 0.927 kg/m3 .4543 kg/m3 1.079 kg/m3 4.543 kg/m3

The density  of 700 kg object  with  a volume of 649 m³  is 1.079  kg/M³

 calculation

  This problem is solved using density  = mass /volume   formula

mass= 700 kg

volume= 649 m³

density is therefore =  700 kg / 649 m³  = 1.079 kg/m³

sry but any answer choices

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
