DATA You set up the circuit shown in Fig. 26.20. where C = 5.00 x 10 −6 F. At time t = 0. you close the switch and then measure the charge q on the capacitor as a function of the current i in the resistor. Your results are given in the table: (a) Graph q as a function of i . Explain why the data points, when plotted this way, fall close to a straight line. Find the slope and y -intercept of the straight line that gives the best fit to the data. (b) Use your results from part (a) to calculate the resistance R of the resistor and the emf ε of the battery, (c) At what time t after the switch is closed is the voltage across the capacitor equal to 10.0 V? (d) When the voltage across the capacitor is 4.00 V. what is the voltage across the resistor?

In the Donkey Kong Country video games you often get around by shooting yourself out of barrel cannons. Donkey Kong wants to launch out of one barrel and land in a different one that is a distance in x of 9.28 m away. To do so he launches himself at a velocity of 22.6 m/s at an angle of 30.0°. At what height does the 2nd barrel need to be for Donkey Kong to land in it? (measure from the height of barrel 1, aka y0=0)
For which value of θ is the range of a projectile fired from ground level a maximum?
90° above the horizontal
45° above the horizontal
55° above the horizontal
30° above the horizontal
60° above the horizontal
A map from The Legend of Zelda: The Breath of the Wild shows that Zora's Domain is 7.55 km in a direction 25.0° north of east from Gerudo Town. The same map shows that the Korok Forest is 3.13 km in a direction 55.0° west of north from Zora's Domain. The figure below shows the location of these three places. Modeling Hyrule as flat, use this information to find the displacement from Gerudo Town to Korok Forest. What is the magnitude of the displacement? Find the angle of the displacement. Measure the angle in degrees north of east of Gerudo Town.
