Based on the information provided, it is not possible to determine the specific scientific law depicted in the picture without further context or description. The image could potentially illustrate various scientific laws, such as the law of conservation of energy or the law of friction.
To determine which scientific law the picture represents, we can analyze the options provided and eliminate those that are not applicable.
1. The law of conservation of mass states that mass cannot be created or destroyed in a closed system. This law is not directly related to the motion of the cart rolling down a hill and does not apply to the given picture. Therefore, we can eliminate this option.
2. The law of friction relates to the resistance between two objects in contact when one slides against the other. While friction may be present in the cart's motion down the hill, it is not the primary focus of the picture. Thus, we can eliminate this option.
3. The law of air resistance describes the force exerted by the air on a moving object. Although air resistance may act on the cart as it rolls down the hill, it is not the specific scientific law being demonstrated in the picture. Consequently, we can exclude this option.
4. The law of conservation of energy states that energy can neither be created nor destroyed, but only transferred or transformed from one form to another. This law seems to be the most relevant to the given picture because it concerns the energy of the system, which includes gravitational potential energy being converted into kinetic energy as the cart rolls down the hill. Therefore, the correct answer is the law of conservation of energy.
In summary, the scientific law that the picture represents is the law of conservation of energy.
