1. A primary coil of a transformer in a toy electric car has 300 turns and the secondary coil has 30 turns. How many volts will be induced when the primary coil is connected to a 9 V battery? The document you upload for this should show how you solved the problem as well as the final answer and correct unit for the answer. 2. Is this a step-up transformer or a step-down transformer? Explain how you know which type it is. The document should have a short description of how you know what type of transformer is being described in this prompt. Make sure to use complete sentences and to use proper language mechanics in your response.

According to rutherford's nuclear theory, most of the volume of an atom is , so the volume of a hydrogen atom cannot be mostly due to the proton.according to rutherford's nuclear theory, the core of an atom (nucleus) contains most of of an atom and is , so the majority of the mass of a fluorine atom cannot be due to its nine electrons.according to rutherford's nuclear theory, the number of negatively charged particles outside the nucleus the number of positively charged particles within the nucleus, so a nitrogen atom has 7 protons and 7 electrons, while a phosphorous atom cannot have 15 protons and 150 electrons.word bank: dense, empty space, more than, mass, particles, the same as, less than, positively charged, negatively charged
