![Pendulum I. Three uniform rods each of mass M =
1.00 [kg], length L = 0.500 [m], and moment of iner-
tia Iem = ML2, is used to construct a rigid body as
shown. What is the period of small oscillations if it was
pivoted at point P? Take the center of mass of the rigid
body to be at point Q.
A. 0.226 [s]
B. 0.335 [s]
C. 1.42 [s]
D. 2.46 [s]
Buoyant. A cubical box, 5.00 [cm] on each side, is fully submerged in a fluid. The gauge
pressure at the top surface of the box is 591 [Pa] and the gauge pressure on the bottom
surface is 1.13 x 10³ [Pa]. What is the density of the fluid?
A. 1.00 x 10³ [kg/m³]
B. 1.10 x 10³ [kg/m³]
A. 170 [kg/m³]
B. 270 [kg/m³]

C. 2.34 x 103 [kg/m³]
D. 4.40 x 105 [kg/m³]

Differences. A fluid flows between two points inside a tube with pressure difference
(P₂ - P₁) of 1.00 x 104 [Pa] and height difference (y2 - y1) of 1.00 [m]. The exit speed v₁
of the fluid is 10.0 [m/s] and the inner diameter of entrance pipe d2 is twice the diameter
of exit pipe d₁. What is the density of the fluid?
