On the other hand, girls prefer to host and attend pretend tea parties. But why do these differences W exist? Advanced Several months after babies are born, female babies like to look at a person's face to read emotions while male infants prefer to look at objects. Few would disagree that men care more about objects while women tend to empathize with others. However, the sex of our brain is not always as clear-cut as the sex of our body. In one experiment, a tough man, who seemed very competitive, was shown to possess a high degree of empathy, while a woman scored the highest in a hand- 10 eye coordination test at which men were thought to do better. This shows that the distinctions that set us apart might not be as clear as we think. 5 I t ZAN Differences between the sexes are hard to understand and so are relationships. What on earth makes people fall in love? According to a report, men prefer a particular waist-to-hip ratio, which indicates reliable fertility, while women 15 care more about a man's height, which is thought to be related to success.

The photoelectric effect can be used to measure the value of Planck's constant. NOTE: The following data are fictional, and will give a result that is quite different from the real value of Planck's constant. Be sure that you do not use the real value of Planck's constant in any calculations here. 1 S -1 Suppose that a photoelectric effect experiment was carried out using light with v = 7.56 × 10¹4 s-¹, and ejected electrons were detected with a kinetic energy of 2.41 × 10-¹1 J. The experiment was then repeated using light with = 9.81 × 10¹4 s and the same metal target, and electrons were ejected with a kinetic energy of 9.09 × 10-¹1 J. Use these data to find a value for Planck's constant (in J • s). Hint. It may help to start by thinking about how you would calculate the metal's binding energy if you already knew Planck's constant.

想問這題的C C選項指的不應該是說 買賣NFT比想像中複雜 但文中所指NFT的買賣那麼複雜，那為什麼不是錯的勒

第 39 至 42 題為題組 As we progress further into the digital age, new terms and technologies seem to pop up everywhere. The latest of these is "NFTs" or non-fungible tokens. If something is fungible, it means that it is able to be replaced by an item of identical value, such as currency. Therefore, a non-fungible token cannot be interchanged; it is unique. NFTs are linked to the blockchain-the digital database that supports online cryptocurrencies like Bitcoin and Ethereum. Let's take a deeper look at NFTs and how people can buy, sell, and trade them. In simple terms, NFTs are one-of-a-kind digital works of art. They can take the form of GIFs, tweets, virtual trading cards, images of physical objects, and more. NFTs tend to attract investors who believe in the future of blockchain technology, and who are willing to spend top dollar to obtain a new form of digital currency. For example, Jack Dorsey's first tweet sold for $2.9 million, a video clip of a LeBron James slam dunk sold for over $200,000, and a decade-old "Nyan Cat" GIF sold for $600,000. Clearly, the NFT market is something to be taken seriously. So, the next question is: how does one participate in it? modi naging dato Basically any digital image can be purchased as an NFT.
