Question

the picture below shows the international space station orbiting earth. which of the following is used to send information from the international space station back to earth? fiber optics infrared radiation gamma rays radio waves a student coils a bare copper wire around a metal rod and attaches the ends of the wire to an ampmeter. he quickly moves a magnet past the coil and notes the resulting current. how could the student alter this apparatus to create a larger current? use thinner wire use insulated wire increase the length of the rod that is used increase the number of times the wire is coiled around the rod laura sees a red flower. which statement best describes why the flower is red? the light that strikes the flower is mostly red. the light that is absorbed by the flower is mostly red. the light that is reflected from the flower is mostly red. the light that passes through the flower is mostly red. use the picture below to answer the question. the spoon appears to be broken where it enters the water because the light is reflected by the water the light is absorbed by the water the light is bent by the water the light is dissolved by the water

Radio waves are commonly used for communication over long distances, including from space to Earth. Fiber optics require a physical medium (not feasible from space to Earth). Infrared radiation has limited range for such long - distance communication without interference. Gamma rays are harmful and not used for information transmission in this context.

According to Faraday's law of electromagnetic induction, \(E = -N\frac{\Delta\Phi}{\Delta t}\) (where \(E\) is the induced electromotive force, \(N\) is the number of turns, and \(\Phi\) is the magnetic flux). Increasing the number of coils (\(N\)) increases the induced emf, which in turn (assuming resistance changes are negligible compared to the emf change) increases the current (\(I=\frac{E}{R}\)). Using thinner wire increases resistance ( \(R=
ho\frac{l}{A}\), where \(
ho\) is resistivity, \(l\) is length, \(A\) is cross - sectional area), which would decrease current. Using insulated wire doesn't change the induction principle relevant to current magnitude here. Increasing the rod length (if it's non - magnetic) doesn't directly affect the magnetic flux change through the coil.

Objects appear a certain color because they reflect that color of light. When white light (which contains all colors) strikes a red flower, the flower absorbs most colors (except red) and reflects the red light. If the absorbed light was mostly red, it would appear a different color (since red is being taken out of the incident light). If the incident light was mostly red, it's a special case (but the general principle is reflection). Light passing through (transmittance) is not relevant for opaque flowers.
