Question

Which of the following quantities has the same S.I. unit as that of pressure?

• A. Work
• B. Energy / Velocity
• C. Energy / Displacement
• D. $mass X (velocity)^2/Volume$

Answer 1

Answer:

$mass X (velocity)^2/Volume$

$$The unit of mass X (velocity)^2/Volume is same as that of energy per unit volume because mass X (velocity)^2 is equal to energy, which is in turn equal to Nm/m^3 = N/m^2$$
