In which of the following activities is force used for pulling?a)Blowi...
Explanation:
Force is a push or a pull that can change the motion of an object. When force is applied in the direction of motion, it is called a push, and when it is applied opposite to the direction of motion, it is called a pull. In the given options, force is used for pulling in the activity of stretching a rubber band. Let's understand this concept in detail.
Force used for pulling:
When an object is pulled, a force is applied to it, which causes it to move towards the direction of the force. This force can be applied through various means, such as ropes, strings, rubber bands, etc. When a rubber band is stretched, a force is applied to it, which causes it to elongate. This force is known as the tensile force, and it is responsible for stretching the rubber band.
Other options:
In the activity of blowing air into a balloon, force is applied to the air inside the balloon, which causes it to expand. This force is a type of push force and not a pull force.
In the activity of cycling, force is applied to the pedals, which causes the bicycle to move forward. This force can be a combination of push and pull forces, depending on the direction of the pedals' motion.
Conclusion:
Thus, we can conclude that force is used for pulling in the activity of stretching a rubber band.
