What error, if any, would the calculated density of the solid have if the material had a hollow center? 1 ) The calculated density would be low, because the volume would be incorrectly measured low.

2) The calculated density would be low, because the volume would be incorrectly measured high.

3)The calculated density would be high, because the volume would be incorrectly measured low.

4)The calculated density would be high, because the volume would be incorrectly measured high.

If the material had a hollow center, the correct option will be

If a material had a hollow center, then volume would be high which results in low density.

The most accurate way to calculate the density of any solid, liquid or gas is to divide its mass in kilograms by its volume in cubic meters. The unit for density is .

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

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.
