Calorimetry - Answer-science of measuring heat Calculate amount of energy released using E=mc(dT) - Answer-Energy released= (mass of water heated)x(specific heat of water)(temp. change) specific heat=1.0 cal/gC 1 Cal=1000 cal What is meant by small calorie "c" and food calories "C"? - Answer-"c" is a scientific calorie which is the energy required to rise the temp of 1 gram of water by 1C "C" is 1000 scientific calories-Food Calories When walking, an average person burns 0.453 Food...

ABCTE -The Solar System and the UniverseTools of the Astronomer - correct answer The basic tool that astronomers use to study celestial objects is the telescope. People tend to be most familiar with optical telescopes, but astronomers use telescopes that span the entire electromagnetic spectrum. Radio Waves - correct answer Radio waves are the longest waves of the electromagnetic spectrum. We use radio waves to broadcast radio, TV, and cellular phone signals. Radio waves are also used to pe...

Discuss the basics of radiologic science CORRECT ANSWER X-rays fall between the gamma ray and ultraviolet wavelength range; xrays have between 0.03 to 3 nanometer wavelengths. (associated with short wavelengths) Describe how xrays are produced CORRECT ANSWER Xrays are the result of a high impact of a large volume of heated negatively charged electrons with a hard surface. When this impact occurs, the electrons rupture with the conversion of electrons to x-radiation. Describe the elements o...
