Of any substance? What about two powders such as 1/2 cup of white flour, then mixing 1/2 cup of salt together with the flour. This would then form a more coarse mixture being that the two particles differ in shape.
Keeping the masses of the objects unchanged, if the distance between the objects is halved, then the magnitude of gravitational force between them will become. Hope this helps please mark brainliest :)
A group of environmentalists were discussing the benefits and drawbacks associated with using fossil fuels. Which argument <span>best </span>fits the conversation?
Fossil fuels are cheaper than alternative forms of energy.Fossil fuel reserves will never be depleted.<span>Fossil fuels are easily renewed. </span><span>Fossil fuel use does not affect the environment.</span>
Yep. And you'll always get equations with units that don't match
<u>Given:</u>
Distance of solvent front = 68 mm
Distance of unknown = 48 mm
<u>To determine:</u>
The rf value
<u>Explanation:</u>
The retention factor or the rf value is given by the ratio of distance traveled by the unknown to the distance traveled by the solvent front
RF = distance by unknown/distance by solvent
RF = 48/68 = 0.706
Ans: the RF value is 0.706
