<span>Four waste materials from copper ore processing are: ore minerals, unwanted rock or gangue, uranium, and pyrite/sulfide minerals. Ore minerals are contained in rock and have potential to be economically extracted, gangue may contain silicate minerals for which there is no economic value, uranium is a frequently-occurring radionuclide found in ore bodies, and pyrite and sulfide minerals may be found in tailings piles during copper processing.</span>
<span>In order to generate a cylinder shape we can use a rectangle or square shape object or thing. When a rectangle or square shape paper or material is rolled horizontally it will get a open cylindrical shape. Therefore the shape of the flag can be square or rectangular as usual.</span>
Question 2: Protons
Question 3: Electrons
Question 4: Protons
Question 5: Im pretty sure its electrons
A, both potential and kinetic energy as mechanical energy is the sum of potential and kinetic energy.
I would be D, The Net Force Applied Will Increase.
Because, B would be out of the question if it's re-guarding the person's friction. Because the more you lean and push the more friction you have within your hands and feet.
Net Force is when Force is acting on a object by another force such as their hands. So if it decreases then there would be no one to open it. But if the Net Force increases then their is more force to apply it open !
Please let me know if i am correct !
