Zorluk: OrtaFundamental and Derived Quantities

Match each physical quantity listed on the left with its corresponding classification and physical description on the right.

  • Electric potential differenceDerived quantity defined as energy transfer or work done per unit electric charge
  • Thermodynamic temperatureFundamental quantity representing thermal state, measured in kelvins (K\text{K})
  • ImpulseDerived quantity defined as the product of force and time interval
  • Luminous intensityFundamental quantity measuring perceived light power per unit solid angle

Cevap

Electric potential difference matches derived quantity defined as work done per unit electric charge; Thermodynamic temperature matches fundamental quantity representing thermal state, measured in kelvins; Impulse matches derived quantity defined as force times time interval; Luminous intensity matches fundamental quantity measuring perceived light power per unit solid angle.
Thermodynamic temperature and luminous intensity are two of the seven fundamental SI quantities. Electric potential difference and impulse are derived quantities because they are expressed through equations involving base physical quantities.

Adım Adım Çözüm

1
Identify fundamental physical quantities
Thermodynamic temperature and luminous intensity are basic independent physical quantities defined by SI standards.
Fundamental quantities cannot be defined in terms of other physical quantities.
2
Identify derived physical quantities and their defining expressions
Electric potential difference (V=WQV = \frac{W}{Q}) and impulse (I=FΔtI = F \Delta t) are derived from basic quantities.
Derived quantities are defined by mathematical combinations of fundamental quantities.
