This exam paper has 1 printed pages (including cover and formula Sheet).. The examination is worth 30 percent of your final mark. 3. The examination consists of three parts. PARTS CONTENT MARKS A MULTIPLE CHOICE 60 Know. & Under, Think. & Inquiry, Application B SHORT ANSWERS 10 Communication C PROBLEM SOLVING 30 Think. & Inquiry, Application TOTAL Please enter your multiple choice answers directly on the answer sheet provided at the end of your EXAM. You may remove the answer sheet and formula sheet but be sure to put your name and section in the space provided. 5. All other answers (Section B and C) must be entered in your answer booklet provided. Insert all materials into your Answer Booklet at the end of your exam. Make sure your name is on all material. Only work shown in the booklet will be evaluated. 6. Please show full solutions along with the relevant formulas for the problems. In your Answer Booklet Clearly Number the problems in consecutive order and do not answer more than one question per page. You can use both the right side and the left side of you answer booklet. Final answers must be clearly indicated with appropriate significant digits and units. Only stationary and calculators are permitted. All answers must be written in black or blue pen only. Do not use a red pen. For office use only: Part A Part B Part C Total

2 Part A: Multiple Choice Questions. Clearly darken (really darken) the circle of the best solution to each question on the answer sheet provided at the end of this section. You may remove the sheet but be sure to write your name and section on the answer sheet in the space provided. (All Questions are marks each; Knowledge: 30; Thinking: 10, Application: 10

3 Part B: Short Answer: Answer each question in your answer booklet clearly and succinctly. Do not write more than a paragraph (50 words). All Questions are worth marks each. (Communication: 10) 1. Indicate the direction of current flow as the magnet approaches the coil.. Draw an electric field in the region around two positive point charges and one negative charge as shown in the diagram. 3. Describe how the interference pattern of light differs when using a two slit compared to a single slit opening. 4. In reference to the speed of light, what does Einstein mean when he described the speed of light as being Relative? 5. What is the difference between Nuclear Fission and Nuclear Fusion?

4 Part C: Problem Solving. Complete the following two questions in the answer booklet provided. Clearly Number the problem and do not answer more than one question per page. You can use both the right side and the left side of you answer booklet. Write your final solution including all formulas and calculations in the answer booklet provided. Also, in your Final Answer provide a reasonable number of significant digits and the appropriate units. 1. A medieval prince trapped in a castle wraps a message around a rock and throws it from the top of the castle wall with an initial velocity of 1 m/s [4 above the horizontal]. The rock lands just on the far side of the castle s moat, at a level 9.5 m below the initial level. Determine the rock s: (5 marks, Thinking & Inquiry) (a) time of flight (b) width of the moat (c) velocity at impac. A car of mass kg negotiates a level curve at a constant speed of m/s. The curve has a radius of 85 m. (5 marks, Application) (a) Draw a Free Body Diagram of the car and name the force that provides the centripetal acceleration. (b) Determine the magnitude of the force named in (a) that must be exerted to keep the car from skidding sideways. (c) Determine the minimum coefficient of static friction needed to keep the car on the road. 3. A.5 kg block is placed on an inclined plane that is then tilted to the point where the block just starts to move. This occurs at an angle of 5. The coefficient of kinetic friction is.35? (4 marks, Thinking & Inquiry) a) Draw a free body diagram of this situation, including alignment of x + and y+ Axis. b) What force must be applied to the block in order to accelerate it up the ramp at 9.8 m/sec.

5 4. Two balls of equal mass m undergo a collision. One ball is initially stationary. After the collision, the velocities of the balls make angles of 31.1 and 48.9 relative to the original direction of motion of the moving ball. (4 marks, Thinking & Inquiry) (a) Draw a diagram showing the initial and final situations. (b) If the initial speed of the moving ball is.5 m/s, what are the speeds of the balls after the collision? 5. An electron accelerates from rest through an electric field and into a magnetic field as shown in the diagram below. The plates have a potential difference of 85 V and the magnetic field has a magnitude of 0.75 T. (Remember: me = kg and e = C.) (5 marks, Application) (a) Calculate the initial speed of the electron upon entering the magnetic field. (b) Calculate the magnitude and direction of the magnetic force on the electron. (c) Calculate the radius of the electron s circular path. 6. A student creates a two-point source interference pattern in a ripple tank with two sources operating in phase. A point on the eighth nodal line is 1.5 m from the center of the two sources and 48.0 cm from the perpendicular bisector of the two sources. If the source separation is.75 cm, find the wavelength of the waves. (4 marks, Application) 1.5 m 8 th Max 48 cm.75 cm bisector 6. An astronaut has completed the first journey to our closest neighboring star, Alpha Centenary which is 4. light years away. Traveling at m/sec, how long did the journey appear to take for: (3 marks, Thinking & Inquiry) a) the astronaut b) an observer on Earth
