14. On a test track, the Ferrari F430 was measured to accelerate at 15 mph/s. Using
the formula below, determine how many
seconds it takes for it accelerate from 0
mph to 60 mph. SELECT THE BEST ANSWER.

you need to give more information

a electronegativity decreases beacuse the size of nucleus is bigger.

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.
