Assignment Instructions Step 1: Gather materials and necessary information. a) You will collect information about genetically modified foods, including: • A description of what genetically modified foods are • A list of crops that are typically genetically modified • An explanation of why crops are genetically modified • A description of how crops are genetically modified • A list of how genetically modified crops affect society and the environment b) Be sure to keep a list of your references so you can cite them properly later. c) Ask your teacher where you should save your presentation as you work on it. Your teacher

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.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
