Identify radiation B and provide an explanation for the differing deviations observed in the paths of radiations A and C as they pass through an electric field, as depicted in figure 15.
Determine the frequency of X-rays produced in an X-ray tube with a 12000V acceleration voltage, assuming full energy conversion, using Planck's constant and the charge of an electron.
Name the components labeled A and B in the X-ray tube, explain how altering the potential across P affects X-ray intensity, and describe the cause of the high temperature in the tube during operation.
Using an appropriate ray, find the focal length (f) and radius of curvature (r) of the concave mirror that forms the image I of the object O shown in the diagram.
Explain why when a vibrating tuning fork with a frequency of 512Hz is brought close to two test tubes with water levels as shown in the image, it produces a loud sound in test tube X but not in test tube Y.
Explain the reason behind the observed deflection of the candle flame in Figure 2, where a thin wire is connected to a charge generator and positioned nearby.
Explain which spring balance will show a lower number when the block is about to start moving in the student's experiment to measure static friction with wooden blocks.
Determine speed limit violation, calculate max tire braking force during skid, and explain the impact of reduced wet road braking force on stopping distance, assuming constant initial speed.
Calculate the centripetal force, identify the string breakage point, determine the landing height, and find the horizontal distance traveled by a 100g stone in a 0.4m radius vertical circle making 2 revolutions per second.
Sketch a volume (cm3) vs temperature (°C) graph on the provided grid, marking the absolute zero temperature with 'T', and state the two assumptions in the experiment.
Explain the roles of concentrated sulfuric acid, the stirrer, and the measurements in confirming Charles's Law in the gas volume-temperature experiment.
