1. Use the following questions to fill in the table of properties: Which of these are magnetic? Float in water? Sink in water ? Dissolve in water ? Properties: Sand, Iron Fillings, Salt, Plastic Beads

magnetic- Iron Fillings

Sink in water- Sand

Dissolve in water- Salt

Float in water- Plastic Beads

Explanation:

A general guiding principle that will determine what objects will sink or float in water is this; when the weight of an object is greater than the weight of an equal volume of water, that object is denser than water hence it will sink in water. Similarly, when the weight of an object is less than the weight of an equal volume of water ,then that object is less dense than water hence it will float in water. Thus sand sinks in water (more dense than water) while plastic beads float in water (less dense than water).

Iron fillings are attracted by magnets hence they are magnetic while salt dissolves freely in water since it is an ionic substance.

passed in september 1935, these laws are known as nuremberg laws.   they forbid jews from marrying but not directly forced them to divorce aryans. what is most noticeable is the fact that the jews were defranchised, meaning by this that they were not expected to have any civil rights, including the right to vote. the right answer is deprived of the right to vote.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
