Melissa planted a sapling in her garden. she measured its height with a ruler. the tree was 15 centimeters tall. after a week, she measured it again. this time, the tree measured 25 centimeters. how many millimeters did the tree grow? the tree grew millimeters in a week.

100 Millimeters

Explanation:

The tree's first measurement = 15 centimeters

The tree's measurement after a week =25 centimeters

The difference in growth = 25 - 15 = 10 cm

Since we are asked to find out how many millimeters the tree grew, we convert our result to millimeters.

Conversion Unit: 1 centimeter = 10 Millimeters

Therefore: 10 cm = 10 X 10 =100 Millimeters

The tree grew 100 Millimeters in a week.

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.
