Answer:Well There is many ways to increase friction between objects. One being rubbing the two objects together quicker and harder. If there is any sort of wetness or anything related to that make sure to dry the surface between the two objects you want to create friction between so it will be more effective.
Explanation:
Answer:
Density of the He atom = 12.69 g/cm³
Explanation:
From the information given:
Since 1 mole of an atom = 6.022x 10²³ atoms)
1 atom of He =
The volume can be determined as folows:
since the diameter of the He atom is approximately 0.10 nm
the radius of the He = = 0.05 nm
Converting it into cm, we have:
Assuming that it is a sphere, the volume of a sphere is
=
=
=
Finally, the density can be calcuated by using the formula :
D = 12.69 g/cm³
Density of the He atom = 12.69 g/cm³
