Answer:
Magnetic separation
Sawdust is a non-magnetic material whereas iron shavings are magnetic. When a magnet is brought near a mixture of iron shavings and sawdust, the iron shavings will be attracted to the magnet while the sawdust will not. Thus, the iron shavings will be separated from the sawdust.
Explanation:
Separation techniques makes use of the differences in the properties of components of mixtures to separate theses components, one from another.
In a moxturemof iron shavings and sawdust, a suitable separation technique would be the use of magnetic separation.
The use of this separation technique is abasednonnthe principle that when a magnetnis brought near to a mixture containing magnetic and non-magnetic materials, the magnetic materials will be separated from the non-magnetic materials due to their attraction to the magnet. Sawdust is a non-magnetic material whereas iron shavings are magnetic. When a magnet is brought near a mixture of iron shavings and sawdust, the iron shavings will be attracted to the magnet while the sawdust will not. Thus, the iron shavings will be separated from the sawdust.
Different colors of sedimentary rock are determined by the environment where they are located. For example, red rocks form where oxygen is present. Darker sediments form when the environment is oxygen poor.
So, basically, the weather and surroundings of the rock, so B.
Moving material along certain gradients is necessary for osmosis, diffusion, filtration, and the transport of ions away from similar charges.
Osmosis is the flow of solvent molecules over a semi-permeable membrane from an area of lower concentration to a region of higher concentration Molecules diffuse when they travel from one area of higher concentration to another area of lower concentration The process of filtering involves moving liquid substances through a separating material known as a filter in order to separate solid particles from liquid. Due to the difference in pressures between the solid and liquid substances, this process is made feasible. Because of the difference in electrical potentials between the charges, ions move away from like charges.

Answer:
2
Explanation:
It is going through the air and is moving so that means that it has kinetic energy. But it is also going to go the down, which gives it potential energy.
