06. When you clasp both your palms one over other very tightly, it sticks for a while. why does this happen? Explain
Answers
Answer:
because electromotive force is generated between both surfaces that sticks both hands together for a while

Answer:
If you rub your hands together for several seconds, you'll notice that your hands feel warm. That warmth is caused by a force called friction. Friction happens when you overcome the resistance of one object rubbing against the other. Friction reduces the speed of the moving objects and it even stops the motion of the object. Friction between the objects produces heat. This results in the wastage of energy in the machines. There will be wear and tear on the machine parts due to friction.
Explanation:
Friction is a force, the resistance of motion when one object rubs against another. Whenever two objects rub against each other, they cause friction. Friction works against the motion and acts in the opposite direction. The amount of friction depends on the materials from which the two surfaces are made. Friction is caused due to the irregularities on the two surfaces in contact. Even the smoothest surfaces have minute irregularities in them and these irregularities of the two surfaces interlock into each other and create friction. The larger the irregularities more is the more friction. Friction is a contact force when two surfaces interact. Hence, friction depends on the surface of contact as the surface of contact increases the frictional force also increases.
