1 Over the range microwaves require a minimum 66 mounting height from floor to top of the micro. 2  The 66 from the floor dimension will allow approximately 13-16 between the cooktop and the bottom front of the microwave.
With that said, calculating the radio delay between Earth and Venus -- the closest planet to Earth -- is now simply a math problem. However, the distance between Venus and Earth varies throughout the year of each; at its closest, Venus is about 38 million km from Earth, and about 261 million km at its farthest.ne major problem with intrasolar and interstellar communication is the vast distances involved. On Earth, radio communication is all-but instantaneous, because radio waves travel at the speed of light, approximately 300,000 kilometres per second.
