The static friction is a friction between two objects that are not moving relative to each other.
The static friction must be overcome by an external applied force before the object can move.
The max static fraction (Fμ) is defined as the product of the coefficient of static friction (μ) and the normal force (Fn).
The normal force 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 max. force of friction will be
Note that: the object will not be moved until the applied force more than the max. fraction force as we see in our problem.
the word that best describes martin luther king jr.'s tone in the video is dignifiedexplanation:
martin luther king, jr. was a social activist and baptist minister who played a key role in the american civil rights movement from the mid-1950s until his assassination in 1968. the video shows his manner and attitude having or showing a composed or serious manner that is worthy of respect so dignified is the correct answer
