Please show steps how to get to answer (explanation) **Educational Resource: Physics Concepts****Question 6:** A step-up transformer steps up voltage by ten times. If voltage input is 120 volts, voltage output is A) 60 V. B) 120 V. C) 1200 V. D) 12000 V. E) none of the above**Question 7:** If an electron vibrates up and down 1000 times each second, it generates an electromagnetic wave having a A) period of 1000 s. B) speed of 1000 m/s. C) wavelength of 1000 m. D) frequency of 1000 Hz. E) wavelength of 1000 km.**Question 8:** Distant bright snowy mountains appear yellowish because A) they are far away. B) blue has been scattered away from light reflected from the mountains. C) the color yellow looks just right. D) of nature's wonderful preferences.**Explanation of Concepts:**1. **Transformers and Voltage:** Transformers are electrical devices that modify voltage levels. A step-up transformer increases the voltage, while a step-down transformer decreases it. In this question, a tenfold increase means multiplying the input voltage by 10.2. **Electromagnetic Waves:** These waves are generated by vibrating electrons. Frequency, measured in Hertz (Hz), indicates how many cycles occur per second. This concept is crucial in understanding how electromagnetic waves propagate.3. **Light Scattering:** The phenomenon that explains why we perceive different colors under various conditions is crucial in atmospheric and visual science. When light reflects off surfaces, like snowy mountains, scattering can cause color changes due to atmospheric conditions.

(6) Input voltage stepped-up n times imply the output voltage is n fold that of the input voltage.…
