मुलांच्या संगोपनाच्या अशा जाहिराती ज्यात पुरुष जबाबदारी उचलत आहेत​

Answer 1

Answer:

Friction is a force between two surfaces that are sliding, or trying to slide, across each other. For example, when you try to push a book along the floor, friction makes this difficult. Friction always works in the direction opposite to the direction in which the object is moving, or trying to move.
