Q: Q: What occurs when an unstable nucleus emits a beta particle and energy? Read this paragraph and choose the correct option from the provided answers: Beta decay occurs when an unstable nucleus emits a beta particle and energy. A beta particle is an electron. It has a charge of -1. In nuclear equations, a beta particle is represented by the symbol . The subscript -1 represents the particle's charge, and the superscript 0 shows that the particle has virtually no mass. Nuclei contain only protons and neutrons, so how can a nucleus emit an electron? A neutron first breaks down into a proton and an electron (see Figure below ). Then the electron is emitted from the nucleus, while the proton stays inside the nucleus. The proton increases the atomic number by one, thus changing one element into another. Choices: - nucleus decay - alpha decay - methane decay - beta decay A:
A: beta decay

Q: What is the most common way to classify stars? Read this paragraph and choose the correct option from the provided answers: The most common way of classifying stars is by color as shown, in Table below . Each class of star is given a letter, a color, and a range of temperatures. The letters don't match the color names because stars were first grouped as A through O. It wasn't until later that their order was corrected to go by increasing temperature. When you try to remember the order, you can use this phrase: "Oh Be A Fine Good Kid, Man. ". Choices: - by age - by distance - by size - by color A:
**Answer**
by color
