I measure the density of gold to be 17.4 g/mL. If the actual value is 19.3 4 poin g/mL. Calculate the percent error.

d.) circle motion requires a force to give it a centripetal acceleration.

where are the choice options?

explanation:

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
