1.2Length, Mass and Time

1. The unit of pressure (p) is [N/m2]. Which of the following equations could be another equation for the pressure?

  1. p = ρ × g/h
  2. p = ρ/g × h
  3. p = ρ × g × h
  4. p = ρ × g + h

Additional info: h is the depth (unit: m), g is gravitational field strength (unit: m/s2), ρ is the density (unit: kg/m3).

Correct Answer: C

2. A car driver notices a road sign, which indicates, "not faster than 30 m/s". What is the maximum allowed speed (in km/hr) to avoid fines from police officers?

  1. 100 km / hr
  2. 108 km / hr
  3. 110 km / hr
  4. 112 km / hr

Correct Answer: B

3. A student reads in an old book that the equation of period T in a simple pendulum is

T = 2π × √l/

where the quantity ⊡ cannot be read due to the book's amortization. Which quantity does the quantity ⊡ represent?

  1. Gravitational acceleration
  2. Gravitational force
  3. Velocity of pendulum
  4. Total time of pendulum's motion

Correct Answer: A
