Answer:
Remember: in physics and music, frequency equates to pitch, and amplitude equates to loudness. Also, remember frequency is inversely proportional to wavelength- remember this!
Thus, (B) should be the correct answer, because, think about it, if a note is higher, than the wavelength should be shorter so the length should also be shorter, but in the case of B, if the cable is longer or thicker then the wavelength gets longer. Therefore, going from low to high, the string should be getting shorter, due to the fact that as wavelength gets shorter, frequency gets higher.
Answer
decreases
Explanation
Frequency and wavelength are inversely proportional to each other. And if wavelength increases, its frequency decreases.
Solar Radiation is just light, or heat, from the sun (solar)
For number 2:
Speed is related to kinetic energy because kinetic energy is the energy of motion.
