     True
     False
  • 2
    - If the period of signal on oscilloscope is 5 cm representing 50 ms, then the amplitude of this signal is 10 mV
     True
     False
  • 3
    - Biosignals are being generated by the interaction of the organism with an external stimulus (e.g. with electromagnetic field, ionizing radiation, etc.)
     True
     False
  • 4
    - A comparative method of measurement (e.g. the density using a pycnometer) is based on the measurement of given quantity on unknown sample and also on the sample, which characteristics (measured quantity) are known
     True
     False
  • 5
    - When we adjust zero equilibrium position of the balance (e.g. by setting it by pushing
    the „zero“ button) it is guaranteed that by balancing the object (e.g. by reading the mass
    from the display) we get correct result.
     True
     False
  • 6
    - Using linear interpolation method, if 3 kg correspond to 6 ml and 4 kg corresponds to 8 ml, then 3.5 kg corresponds to 7 ml
     True
     False
  • 7
    - It is easier to measure directly the amount of substance (in mole) than the mass
     True
     False
  • 8
    - Accuracy of volume measurement is usually higher than the accuracy of weighing
     True
     False
  • 9
    - An example of linear relationship: 3-fold input results in 3-fold output
     True
     False
  • 10
    - An example of linear relationship: 3-fold input does not result in 3-fold output
     True
     False
  • 11
