Transcript of science project

BY: Andrew Mularski, Trevor Holmes, Hunter Lee, and Owen Grosser Can You Hear Me Now? The Cause and the Effect of the Disturbances The Physical Features Of the Sun The Sun’s extends from the center to about 0.25 of the solar radius. It has a density of 150 g/cm3 and a temperature of close to 13,600,000 F. Energy is produced by nuclear fusion during a series of steps called the proton-proton(P-P) chain, converting hydrogen to helium. The core is the only part of the Sun that produces a good amount of heat through fusion(99%). The rest of the star is heated by energy that is transferred outward from the core and the layers. The energy must then travel through many layers to the solar photosphere before it escapes into space as Kinetic energy(sunlight in this case). The P-P chain occurs around 9.2×1037 times each second. Fusing hydrogen into helium releases around 0.7% of the fused mass as energy, so the Sun releases energy at the mass-energy conversion rate of 4.26 million metric tons per second.

The Sun produces energy by the nuclear fusion of hydrogen into helium in its core. What that means is that, since there is a huge amount of hydrogen in the core, these atoms stick together and fuse into a helium atom.

Solutions to the problem As electromagnetic waves, and in this case, radio signals travel, they interact with objects and the media in which they travel. As they do this the radio signals can be reflected. These interactions cause the radio signals to change direction, and to reach areas which would not be possible if the radio signals travelled in a direct line. Solutions we could have would be to predict the next possible storm and then prepare for it. How to predict the storms We can predict the storms because there are solars maximums and minimums that cycle every 11 years
