Which among the following is a scalar quantity? Correct Answer Volume

All physical quantities are classified into two types:

Scalar Quantity:

  • A physical quantity having magnitude only is called a scalar quantity. They have numerical value only and these quantities do not specify the direction
  • Example: Length, Time, Speed, Mass, volume, Density, Pressure, Temperature, Energy, Work, Power

Vector quantity:

  • A physical quantity having both magnitude and direction is called vector quantities. It is represented by a straight line with an arrowhead
  • Example: Displacement, Velocity, Acceleration, Force, Momentum, Weight

Four  matrices  M1, M2, M3 and M4 of dimensions p×q, q×r, r×s and s×t respectively can be multiplied in several ways with different number of total scalar multiplications. For example when multiplied as [(M1 × M2) × (M3 × M4)] the total number of scalar multiplications is  pqr + rst + prt. When multiplied as [((M1 × M2)× M3)) × M4], the total number of scalar multiplications is pqr + prs + pst. If p = 10, q = 100, r = 20, s = 5 and t = 80, then the minimum number of scalar multiplications needed is:
