The normal force acting upon the car is best represented by arrow A. The force of gravity acting upon the washers is best represented by arrow D. The applied force on the car is best represented by arrow C.
Explanation:
The normal force is the reaction force which acts in upward direction when object is in contact with another stable object. In the given figure, weight of car is acting downwards represented by B and normal force acting in the upward direction is represented by A.
The washer is hung from the pulley. The force of gravity always acts in the downward direction. It is represented by arrow D in the figure.
The applied force on the car is represented by arrow C towards right.
DNA sequences similarity among various organisms may be used to establish evolutionary relationship among living organisms. ... Organisms or animals whose DNA sequences are similar share common evolutionary origin.
