Mrs. Marlow's class is conducting an investigation of a mixture of sand, iron filings, and salt. They were told that they must separate the mixture into pure sand, pure iron filings, and pure salt using only the physical properties of each component using the following supplies: bar magnet

filter paper

plastic funnel

water

What is the BEST procedure for the students to follow in order to separate the mixture?

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

answeridentity;

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
