Question

Harmful substances that are sold illegally but are taken only under medical supervision in prescribed doses by sick pperson

Answer 1

Explanation:

physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
