Ques: Q: What is the opposite of nuclear fusion? Read this paragraph and choose the correct option from the provided answers: Nuclear fusion is the opposite of nuclear fission. In fusion, two or more small nuclei combine to form a single, larger nucleus. An example is shown in Figure below . In this example, two hydrogen nuclei fuse to form a helium nucleus. A neutron and a great deal of energy are also released. In fact, fusion releases even more energy than fission does. Choices: - Solar Power - energy fission - might fission - nuclear fission A:
Ans: nuclear fission

Ques: Q: What is the name of the smallest planet in our solar system, which is also nearest to the sun? Read this paragraph and choose the correct option from the provided answers: Mercury is the smallest planet. It has no moon. It is also the planet closest to the Sun. Pictured below is the surface of Mercury covered with craters ( Figure below ), like Earth's Moon. Many of the impact craters are billions of years old. This means that Mercury hasn't changed much geologically for billions of years. It has no plate tectonics. With only a trace of an atmosphere, it has no weather to wear down the ancient craters. Choices: - mars - jupitor - earth - mercury A:
Ans: mercury

Ques: Q: What is the the force of attraction that holds together ions? Read this paragraph and choose the correct option from the provided answers: An ionic bond is the force of attraction that holds together positive and negative ions. It forms when atoms of a metallic element give up electrons to atoms of a nonmetallic element. Choices: - covalent bond - soluble bond - magnetic bond - ionic bond A:
Ans:
ionic bond
