1. Question: How does electromagnetic energy travel? (Use the reading below to answer the question)
Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. The human eye can only detect only a small portion of this spectrum called visible light A radio
detects a different portion of the spectrum, and an x-ray machine uses yet another portion, NASA's scientific instruments use the full range of the electromagnetic spectrum to study the Earth, the solar system, and the
universe beyond
When you tune your radio, watch TV, send a text message, or pop popcom in a microwave oven, you are using electromagnetic energy. You depend on this energy every hour of every day. Without it, the world you know. com
not exist
Through a medium
On a spectrum
In waves
By forces

The wilson chamber is used to study: direction, speed, and distance of radioactivity the intensity of radiation the appearance of individual atoms all of the above

Hot air balloons float in the air because of the difference in density between cold and hot air. in this problem, you will estimate the minimum temperature the gas inside the balloon needs to be, for it to take off. to do this, use the following variables and make these assumptions: the combined weight of the pilot basket together with that of the balloon fabric and other equipment is w. the volume of the hot air inside the balloon when it is inflated is v. the absolute temperature of the hot air at the bottom of the balloon is th (where th> tc). the absolute temperature of the cold air outside the balloon is tc and its density is ďc. the balloon is open at the bottom, so that the pressure inside and outside the balloon is the same. as always, treat air as an ideal gas. use g for the magnitude of the acceleration due to gravity.
