question:Read the following article and select the best answer. Article: In the 1500s, South American fishermen said that the sea became warmer every few years. They gave this special event a Spanish name 'El Nino', meaning 'the baby'. It is called 'the baby' because it arrives around Christmas. El Nino is a huge area of warm water in the middle of cold water in the Pacific Ocean. It happens every two to seven years. It moves around the ocean and becomes bigger and smaller at different times. This warm water affects the weather. It is always raining over El Nino. El Nino contains a lot of energy. Scientists think this energy is formed when wind comes from the northern half of the world. The winds blow across warm sea water in the south. When the strong wind hits the warm water, violent weather happens. Scientists think that El Nino existed for many thousands of years. El Nino affects every person in the world because it affects the entire world's weather. It can bring the rain that farmers need. It can bring storms that destroy homes. It can mean that fishermen cannot catch fish, and it can bring floods. There is nothing we can do about El Nino. It is an event of nature. We can help the world's weather by trying to stop the greenhouse effect and air pollution. The most important job for scientists is to learn how to predict when El Nino is going to bring dangerous weather. Then, people can try to prepare for storms, floods and droughts. New technology like satellite pictures and temperature measuring equipment can help. Still, it is very hard to say when or where El Nino will cause damage. Question: It happens _ . - every year - every month - every seven years - every two to seven years A:
answer:It happens every two to seven years.
question:What are formulas of the quantum theory of light? What is the equation of quantum theory of light? Please tell me if those questions are the same.
answer:The two questions you've asked are related but not exactly the same. The first question asks for multiple formulas involved in quantum theory of light, whereas the second question asks for a specific equation of quantum theory of light. Let me address both questions below: 1. Formulas of the quantum theory of light: There are several formulas and principles in the quantum theory of light, which primarily revolves around understanding the interactions between light and matter in the context of quantum mechanics. Here, I will provide a few key equations that are relevant to this topic: a) Planck's Law of Radiation: E = h * frequency = h * (speed of light) / wavelength where E is the energy, h is Planck's constant, and frequency and wavelength are characteristics of the light wave. b) Einstein's Photoelectric Effect: E_photon = E_k + W where E_photon is the incoming photon's energy, E_k is the kinetic energy of the emitted electron, and W is the work function of the material. c) De Broglie Wavelength: λ = h / p where λ is the deBroglie wavelength, h is Planck's constant, and p is momentum. d) Heisenberg Uncertainty Principle: Δx * Δp ≥ (h/2π) / 2 where Δx is the uncertainty in position, Δp is the uncertainty in momentum, and h is Planck's constant. 2. Equation of quantum theory of light: If you're looking for a specific equation that represents the core idea of the quantum theory of light, the most suitable equation would be Planck's Law of Radiation (E = h * frequency) that I mentioned earlier. This equation quantizes the energy of light into discrete packets called quanta, or photons, and is at the foundation of the quantum theory of light. In summary, the first question seeks multiple formulas in the realm of quantum theory of light, while the second question seeks a specific, core equation that represents the quantum theory of light. While they do have overlapping content, the questions are not the same.
question:Article:5 October 2016 Last updated at 17:26 BST The bird, powered by a Rohm microcontroller, has been enhanced with two extra wings since its appearance last year. But as BBC Click reporter Dan Simmons found out, it can be a little tricky to control. BBC Click will have more from Ceatec on this weekend's television show. Find out more at BBC.com/Click and @BBCClick. Summarize the main points of that article.
answer:This brief news article revolves around three main points: 1. Enhancements to a Bird Robot: A major point in this article is the noticeable enhancement made to a bird robot. Compared to its previous model from the last year, the bird now has two extra wings. It is powered by a Rohm microcontroller, which is essentially an integrated circuit that can control various functions depending on the programming and embedded software. It suggests technological advancements in the realm of robotics, causing the bird-like robot to be more sophisticated with added features. 2. Challenge in Controlling the Bird: As BBC Click reporter, Dan Simmons, discovered the modified bird robot can be difficult to operate. This implies that although the technical improvements have resulted in more features, they have also added complexity to the interface or operation of the robot. It may require additional skills or some level of expertise to successfully maneuver it. 3. Upcoming Coverage from Ceatec: The third key point is about an upcoming episode of BBC Click, a television show providing the latest tech news and reviews. It would cover more about this bird robot and probably more highlights from Ceatec (Combined Exhibition of Advanced Technologies), an annual event that showcases advancements in electronics and IT technologies. Readers are encouraged to check out the show for more details, as well as visit the dedicated website and official Twitter account for BBC Click.
question:1967 : The steel industry is established and the British Steel Corporation is nationalised . 1967 : The steel industry is born and the British Steel Corporation is nationalised . Select your answer from the options. Do these sentences mean the same thing? OPTIONS: [-] no [-] yes
answer:[-] yes These sentences mean the same thing because both state that the steel industry was established (or born, which means the same thing here) and the British Steel Corporation was nationalised in 1967. The only difference in the sentences is the use of "established" and "born," both of which refer to the creation or inception of the industry, so the overall meaning remains the same.
