QUESTION 4 The diаgrаm fоr this questiоn, Figure 4.1, shоws two metаl plates, X and Y, with a metal ball moving between them. Refer to addendum page Figure 4.1 4.1 The two metal plates have no charge before the power supply is connected. When plate Y is connected to the positive terminal of the power supply, the plate becomes positively charged. Explain how plate Y gains a positive charge. (2) 4.2 The metal ball becomes positively charged when it touches plate Y. The metal ball then moves away from plate Y towards plate X. Explain why the metal ball moves away from plate Y. (2) 4.3 Give a reason why the ball is made of metal. (1) 4.4 When the metal ball moves away from plate Y to plate X, a charge of 5.1 × 10-6 C is transferred. 4.4.1 State the formula linking charge transferred, current and time taken. (1) 4.4.2. Calculate the current if the metal ball takes 0.45 seconds to travel from plate Y to plate X. (2) 4.4.3 Suggest why the current increases if the voltage of the power supply is increased. (1) 4.4.4 Give the name of the apparatus that can be used to measure current. (1) TOTAL QUESTION 4: [10]

Yоu аre а reseаrcher wоrking fоr the Centers for Disease Control and you have been commissioned to find the pathogen responsible for a disease outbreak among humans living in Remote Town, USA. This town is located in a remote area of the Rocky Mountains, and is almost completely surrounded by dense forest and abundant wildlife. It has undergone a recent economic boom due to the employment of many townspeople by a local company harvesting large trees in the area for lumber production. When you arrive at Anytown and talk to the local doctors and family members of the outbreak patients, you collect the following facts: (1) So far, 7 people have fallen severely ill to a pneumonia-like respiratory illness; all of these patients were cutting down trees in the same small area of dense forest; (2) All patients mentioned to their families that they were bitten by a strange-looking orange-striped squirrel living in the trees they were cutting down; (3) All patients became severely ill within 5 days of exposure to the orange-striped squirrels; (4) Standard clinical microbiology culture-dependent tests have not been able to grow the pathogen responsible for this disease; (5) You suspect that the pathogen is an intracellular bacterial pathogen, due to the presence of rod-shaped bacteria inside lung epithelial cells isolated from outbreak patient lung biopsies but absent from lung biopsies collected from uninfected patients; (6) 10 orange-striped squirrels have been captured from the same area where all infected patients were chopping down trees. None of the captured squirrels show any sign of illness or respiratory distress. (7) After all samples were collected from outbreak patients, they were treated with a mixture of antibiotics. All patients responded well to this treatment and made a full recovery. Case study question 2: Assume you have identified two bacterial 16S rRNA sequences that are present in the outbreak patient samples but not the control (uninfected) samples. Bioinformatics analysis reveals that one of these sequences is 98% similar to Streptococcus pneumoniae (a common resident of the human upper respiratory tract) and the other sequence is relatively novel, since the best match to known bacterial 16S rRNA sequences is only 39% similar to Yersinia pestis. You hypothesize that this novel bacteria was transmitted from the orange squirrels to the infected patients. Of the experiments below, which would be the best one to verify this novel bacteria is present in both the orange squirrels and infected patients?
