This study source was downloaded by from CourseH on :59:02 GMT -06:00 Module 2 Assignment: Part 2: SES 141: Energy in Everyday Life (2020 Spring - B) 3/29/20, 12:36 PM Forming bonds requires a catalyst. Forming bonds releases energy. Forming bonds is endothermic. Forming bonds requires an acceleration. Forming bonds is an unstable process. Question 2 2 / 2 pts The act...

Question 1 3 / 3 pts The process of photosynthesis stores about 6 kJ/kg as chemical energy This study source was downloaded by from CourseH on :12:22 GMT -06:00 Module 3 Assignment: Part 2: SES 141: Energy in Everyday Life (2020 Spring - B) 4/6/20, 1:22 PM is the same as respiration. produces sugars and oxygen. stores about 60 kJ/kg as chemical energy produces sugars and carbon dioxide. is the opposite of respiration.

Question 2 3 / 3 pts Properties of a thermal radiator include Hotter objects emit less light for a given area. Hotter objects look bluer Hotter objects look redder Hotter objects emit more light for a given area. The power radiated is proportional to the temperature raised to the fourth power. The power radiated is inversely proportional to the temperature.

Differences between fission and fusion include fusion combines light nuclei into heavier nuclei. fission combines light nuclei into heavier nuclei. fusion breaks apart heavier nuclei into lighter nuclei. fission breaks apart heavier nuclei into lighter nuclei.

Some properties of a voltage and a current are a voltage is a force times a charge a voltage is an energy times a charge a voltage is a potential energy per unit charge a charge that is in motion causes a current. a charge that is not moving causes a current. a current is a charge per second.

Winter Roberts Solar Water Desalination April 17th, 2020 SES 141 For this project I had glass containers because we like to make brownies a lot and the other supplies I had at home as well. I followed the directions step by step to the best of my ability using all the correct ingredients and materials. I have rocks as part of my landscaping in my back yard, so I was able to use those. It was a little bit cloudy today, so I was actually surprised by how much water was collected because it...
