10.Due to friction
11.Due to friction
Explanation:
10. The force of friction acts between the two surfaces by opposing the relative motion of one surface over the other. For example, when the ball rolls on the ground, the force of friction acts between the surface of the ball and the surface of the ground. The irregularities between the two surfaces lock into each other and thus, stop the ball from moving any further unless it is moved by an external force.
11. When meteor falling towards the earth, it enters in the 'earth's atmosphere'. Then mentor hit these gases and air of the earth atmosphere. As a result a friction occurs between the meteor and the atmosphere of earth and due to this friction force meteor falling towards the earth starts burning.
