(PE = mgh) $300 Answer from H3 50 x 9.8 x 5 = 2450 Joules $400 Question from H3 A man pushes a crate along a factory floor by exerting a force of 10 N. If the crate moves a distance of 4.0 m, how much work does the man perform? (Work = force x distance) $400 Answer from H3 4 x 10 = 40 Joules $500 Question from H3 What is 100 degrees Fahrenheit on the Celsius scale? (°C = (°F – 32) / 1.8) $500 Answer from H3 100 – 32 = 37.78 degrees Celsius 1.8 $100 Question from H4 How does a roller coaster show the relationship between gravitational potential energy and kinetic energy? You may draw a diagram to support your explanation. $100 Answer from H4 At the top of the roller coaster, there Is a maximum of potential energy, and As the coaster rolls down the hill it Gains kinetic energy. $200 Question from H4 Explain how a liquid thermometer measures temperature $200 Answer from H4 As the temperature rises, the liquid expands and rises up the tube. As the temperature cools, it contracts and goes down the tube. $300 Question from H4 Is a geostationary satellite really stationary? Explain. $300 Answer from H4 No, a geostationary satellite is traveling in orbit at the same speed as Earth’s rotation so it remains over the same area on Earth. $400 Question from H4 Which electromagnetic wave is Used to kill cancer cells? $400 Answer from H4 Gamma rays $500 Question from H4 Which electromagnetic waves can Be seen by the human eye? $500 Answer from H4 Visible light Final Jeopardy What are the planets in our solar system?
