20 multiple choice 1 point does noise have a significant effect on streaming videos from the cloud? why or why not? no, because analog signals are used to stream from the cloud, and analog signals are not distorted by noise. yes, because digital signals are used to stream from the cloud, and noise makes the signals unreliable. no, because digital signals are used to stream from the cloud, and noise has a minimal effect on their reliability. yes, because analog signals are used to stream from the cloud, and analog signals are distorted by noise. clear my selection 21 multiple choice 1 point you are designing a new home for a cold climate. you want one room in the house to be warmed by the suns energy. which material would be best to use for absorbing energy from electromagnetic waves that have entered the room? a mirror dark fabric a shiny metal clear glass clear my selection

Answer

Answer:

  1. C. No, because digital signals are used to stream from the cloud, and noise has a minimal effect on their reliability.
  2. B. Dark fabric

Explanation:

Step1: Analyze streaming signals

Digital signals are used for cloud - streaming. Noise has less impact on digital signals due to error - correction techniques. So, question 20's answer is C.

Step2: Analyze energy - absorbing materials

Dark colors absorb more electromagnetic radiation (like sunlight) compared to light - colored or reflective materials. Dark fabric is a good absorber, while a mirror reflects, a shiny metal reflects and conducts, and clear glass transmits. So, question 21's answer is B.
