All answers will be checked for plagiarism. Instances of plagiarism can result in probation or possible dismissal from the school.
Grading: Please be sure to follow all guidelines (number of sentences/showing all calculations) and to provide the correct metric units of measure. All questions are 3.33 points. You MUST include units on all your answers.
For any math based questions you must show all your work and explain any numbers that are not clearly understood by the problem. There is a formula sheet for you to use at the end of the exam.

a. If the model bridge weighs 50 N, what will the real bridge weigh?
b. If the model bridge does not appear to sag under its own weight, is this evidence the real bridge, built exactly to scale, will not appear to sag either?
21. Calculate the water pressure in the pipes at the bottom of a high-rise building that is fed by reservoir 60 m above the roof top.

23. When a 57-gram piece of aluminum at 100oC is placed in water, it loses 735 calories of heat while cooling to 30oC. Calculate the specific health capacity of the aluminum.
24. Your classmate says that if all the molecules in a particular liquid had the same speed, and some were able to evaporate, the remaining liquid would not undergo cooling. Do you agree or disagree and what is your explanation to support your answer.
25. Would it be correct to say the Doppler Effect is the apparent change in the speed of a wave due to the motion of the source? Be sure to fully explain your position using at least 3 complete content related sentences.
26. The equation E=hf describes the energy of each photon in a beam of light. If Planck’s constant, h, were larger, would photons of light of the same frequency be more energetic or less energetic. Be sure to explain using at least 3 content related sentences.
27. A radioisotope is place near a radiation detector, which registers 80 counts per second. Eight hours later, the detector registers five counts per section. What is the isotope’s half-life?
28. Write the nuclear equation that describes the following process. Uranium-235 undergoes an alpha decay to produce thorium-231.
29. If the uranium nucleus were split into three pieces of approximately the same size instead of two, would more energy or less energy be released? Defend your answer in terms of Figure 40.14 in your textbook.
30. According to chapter 30 in the course textbook, describe the time it would take for Earth to orbit the collapsed sun if the sun collapsed into a black hole.
