This question requires the use of a capacitor as a variable resistor. In the circuit shown, a wire carries a current 1.5A and is free to move in a vertical direction. The capacitance is given as pF. Question 1: (i) A charge q is initially placed on a plate of area 15 cm2. If a. (ii) What time interval does the charge take to move from right to left? (ii) What time interval does it take to travel from top to bottom? A particle begins at a position z=0 and moves along a line parallel to the negative x-axis. The velocity of the particle is 5ms-1. (i) Find the z-component of the particle's velocity after 10 s.. The water pot has volume 1 dl, and the water level is level. (i) The water is then  . An ac current with frequency 4 Hz and maximum amplitude 6 A, is passed through the coil. The equilibrium position of the pendulum is at. Find the change in the length of the pendulum. The questions in DP Physics are concerned with structures and forces acting on them, how to apply the laws of physics to the real world and how to model real world structures in the lab. Lab questions are similar to exam questions, except that the Physics teacher creates the questions and writes the answers on the board. There are two ways to ask questions in physics. The first is direct questioning, in which you ask the question and wait for a response. Direct questioning may not always be the best way to get good answers. Question 1: (i) Show that a floating load moving with a non-zero velocity, in an electrically insulating medium with zero electric field, will produce no electrostatic or magnetic force. (ii) In the same moving medium, what would be the maximum and minimum velocity of an object? (ii) If the object is at rest, what would be the maximum and minimum force acting on it? The second is indirect questioning, in which you ask a question and the teacher gives you the answer. The teacher writes the answer on the board, and then you go over the answer and explain why it's correct. Question 2: What is the charge on a plate with an area of 7.3 cm2, connected to a battery of a resistance of 0.1Ω? (i) Using a voltmeter, measure the voltage. (ii) What
