Archie has to go to school this morning for an important test, but he woke up late. He can either take the bus or take his unreliable car. If he takes the car, Archie knows from experience that he will make it to school without breaking down with probability . However, the bus to school runs late % of the time. Archie decides to choose between these options by tossing a coin. Suppose that Archie does, in fact, make it to the test on time. What is the probability that he took the bus? Round your answer to two decimal places

Q1. On Tuesday Sasha writes back saying “Here is my cheque for £4,500” She puts it in the post that night. On Friday morning, Sasha’s letter has still not arrived. Later that day Arthur receives a text message from Simon, which reads, “I’ll give you £5000 for the car. I’ll pick it up tomorrow”. Arthur replied “OK”. Explain to Arthur with which party he will have a valid contract. Give full reasons with case law illustrations. (25 marks) 2. Explain with examples why goods should be of satisfactory quality and fit for purpose. (25 marks) 3. Explain with examples how terms are incorporated into a contract. (25 marks) 4. Explain with examples contractual remedies. (25 marks)

Basic information: The drive-through window of a coffee shop experiences an average arrival rate of 2 cars per minute;however,20% of the drivers are dismayed at the number of cars waiting in line and leave, rather than joining the waiting line.The coffee shop has two service windows available and each window has one barista (the server),along with a separate worker who processes the paymen while the barista makes the customer’s drink.You can ignore the time it takes to handle the payment, because each of those workers is very efficient and finishes their work while the drink is made. Also,then ext car in line,if one is waiting,can get to either service window if one is available;so,if a window is open,a car can get to it immediately. Each barista can serve a customer in 1minute. a) What is the capacity utilization of the drive-through system?

Name: _____________________ Wire Resistance and Ohm’s Law PhET MiniLab Introduction: When an electrical potential exists in a circuit, a current may flow. Current is the flow of electrons in a circuit. Resistance in the circuit slows the flow of the electrons, reducing the current in the circuit. We will use the mathematical form of Ohm’s Law frequently when we investigate electric current and circuits later in this unit. Additional Material Needed: Clean Drinking Straw Procedure Part I Wire Resistance: • Blow through the drinking straw. • Cut the drinking straw in half and blow through a half-straw. • Describe the effect of length on ease to blow air through the straw. _________________________________________ • Cut the halves again in half. • With the four pieces, blow through one, then blow through all four made into a larger, square-shaped straw. • Describe the effect of straw size (diameter) on ease to blow air through the straw. ______________________________ • Now, open the PhET Simulation Electricity, Magnets, and Circuits  Resistance in a Wire As wire length (cm) increases, the resistance (Ω) _________________ As wire area (cm2) increases, the resistance (Ω) __________________ As wire density (Ωcm) increases, the resistance (Ω) _______________ Procedure Part II: Ohm’s Law: Electricity, Magnets, and Circuits  Ohm’s Law mA is milliamps, and _________ milliamps equals one Ampere. • Move the potential (volts) and resistance (ohms) sliders and observe the current (amps) As voltage increases, current __________________. As resistance increases, current ________________. Fill out the tables below and check your work in the simulation. ( ½ pt each ) • Remember, the simulation shows milliamps. • You should show Amperes V = I * R 8.0 V A 800 Ω 2.0 V .044 A Ω V .0058 A 430 Ω V .069 A 100 Ω 6.4 V A 300 Ω Conclusion Questions: ( ½ pt each) 1. Incandescent light bulbs have a very thin filament that glows when hot. Thin filaments have very high / low resistance. 2. The 12V battery in your car operates a 25 amp car stereo. What is the resistance of this stereo system? ___________ 3. A “2D” Maglite flashlight runs on 3.0V. What is the current through the bulb if resistance is 15 Ω ? ____________ 4. How many volts must an iPod charger provide to charge an iPOD using .85 Amps at 35 Ω? _____________ 5. You need to buy a long extension cord to power a stereo at your spring break BBQ. You need 200feet. You have a 50 ft cord that will work. You rationalize that four such 50 ft cords will do the job. Is this a good idea? Why or Why not? ___________________________________________________________________________________________
