  • The intensity of the X-ray beam depends on the number of electrons striking the target per second and in the hot-cathode tubes this is controlled by the heater current. The wavelength depends on the voltage across the tube. The penetrating power of the X- rays is thus dependent on the accelerating voltage and the intensity of the beam on the heater voltage.

      Here d<h has been assumed...
  • The restoring force of the spring is always upward

      Restoring force is always upward because the xmin and xmax are both below x=0
  • Note that if d were greater than h, would be above x = 0, and the restoring force would act in the downward direction until the mass descended once more below x = 0.

      thus the direction of the restoring force depends on d, the elongation given
