On eof the forces is inertia. This can happen when you move your furniture to clean under them. When you move an object in a straight line without chanign its composition (e.g moving a chair or a table from one side to the other) you are working with inertia. The secon force is friction. It s present when you clean a surface by rubbing it with a tool like a damp cloth or a mop.
Purely for crystalline structure, "twinning" or repetition of crystal forms can bring about a striated texture on the mineral. Crystal defects and chemical impurities can alter the physical and electrical properties of a mineral. Some minerals can exist in different crystal forms and exhibit "polymorphism." The range in crystal structure can change the mineral's hardness, strength, solubility, electrical properties, melting points, etc.
706000 in scientific notation is 7.06x10^5
Density is the mass of substance per unit volume of a substance. to solve the problem, first calculate the mass of the gas.
mass gas = ( mass of balloon with gas ) - ( mass of balloon )
mass gas = 10.24 g - 2.42 g
mass gas = 7.82 g
so the density
density = m / v = 7.82 g / 5470 cm3
density = 0.00145 g / cm3
