Question: Q: What is the process in which a layer of a second metal is deposited on the metal electrode that acts as the cathode during electrolysis? Read this paragraph and choose the correct option from the provided answers: Electroplating In a process called electroplating, a layer of a second metal is deposited on the metal electrode that acts as the cathode during electrolysis. Electroplating is used to enhance the appearance of metal objects and protect them from corrosion. Examples of electroplating include the chromium layer found on many bathroom fixtures or (in earlier days) on the bumpers and hubcaps of cars, as well as the thin layer of precious metal that coats silver-plated dinnerware or jewelry. In all cases, the basic concept is the same. A schematic view of an apparatus for electroplating silverware and a photograph of a commercial electroplating cell are shown in Figure 19.24 "Electroplating". Choices: - casting - cold fusion - distillation - electroplating A:
Answer: electroplating

Question: Q: Each lymph organ has a different job in what system? Read this paragraph and choose the correct option from the provided answers: Each lymph organ has a different job in the immune system. Choices: - circulatory - respiratory - nervous - immune A:
Answer: immune

Question: Q: What is the scientific term for stored energy an object has due to its position or shape? Read this paragraph and choose the correct option from the provided answers: Why do charges flow in an electric current? The answer has to do with electric potential energy. Potential energy is stored energy that an object has due to its position or shape. An electric charge has potential energy because of its position in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where their potential energy is lower. This is similar to water falling over a dam from an area of higher to lower potential energy due to gravity. Choices: - repeat energy - mechanical energy - new energy - potential energy A:
Answer:
potential energy
