<u>The static friction</u> is a friction between two objects that are not moving relative to each other.
<u>The static friction</u> must be overcome by an external applied force before the object can move.
<u>The max static fraction (</u>Fμ<u>)</u> is defined as the product of the coefficient of static friction (μ) and the normal force (Fn).
Fμ=μ*Fn
<u>The normal force</u> is defined as the net force normal to the surface, for one body had been put on a surface with out any external tension, it equal to the gravitational force (equally in value and oppositely in direction).
Thus, the <u>max. force of friction</u> will be
Fμ= 
<em>Note that: the object will not be moved until the applied force more than the max. fraction force as we see in our problem.</em>
Answer:
B
Polar covalent bonds and van dar Waals forces are weak attractive forces between discrete molecules of a simple molecular structure.
Ionic bonds are strong electrostatic forces of attraction between oppositely charged ions.
Hydrogen bonds are very strong bonds between hydrogen and a highly electronegative atom e.g Oxygen, fluorine, nitrogen
Answer:
B. Containing charged regions
Explanation:
The term i.e. intermolecular forces would be used to explain the attraction forces. Here the interaction would be done between molecules etc that acts between the acts & the other types of particles i.e. neighboring like atoms or ions
So in the given case, the option b would be contributed to the molecules that have intermolecular forces
hence, the option b is correct
A clear glass panel can become a mirror by simply being coated with silver on its back surface, which creates images by reflection. You can also use mirror-effect spray paint. Hope I helped some :)
