Dallia is in the process of measuring the density of a green oil. She is using a U-shaped tu filled with blue water. She carefully pours some of the oil in one end of the tube, making su they don't mix and letting them settle to a static configuration. She then measures the heigh shown in the figure. She measures h₁ = 2.5 cm, h₂= 3.3 cm, and h3 = 8.2 cm. A M₂ What is the density of the oil? B Without performing any calculations, compare the pressure at points A and B as mark in the diagram. Explain your reasoning. (Hint: all the fluids are static at the mome shown in the diagram.) What is the gauge pressure at the interface between the oil and the water?

One student uses a meterstick to measure the thickness of a textbook and obtains 4.3 cm 0.1 cm. Other students measure the thickness with vernier calipers and obtain four different measurements: (a) 4.32 cm 0.01 cm. (b) 4.31 cm 0.01 cm, (c) 4.24 cm 0.01 cm, and (d) 4.43 cm 0.01 cm. Which of these four measurements, if any, agree with that obtained by the first student?
A surveyor measures the distance across a straight river by the following method (Fig. P1.6). Starting directly across from a tree on the opposite bank, she walks d = 100 m along the riverbank to establish a baseline. Then she sights across to the tree. The angle from her baseline to the tree is 0 = 35.0. How wide is the river? Figure P1.6

A sidewalk is to be constructed around a swimming pool that measures (10.0 0.1) m by (17.0 0.1) m. If the sidewalk is to measure (1.00 0.01) m wide by (9.0 0.1) cm thick, what volume of concrete is needed and what is the approximate uncertainty of this volume?
A surveyor measures the distance across a straight river by the following method: starting directly across from a tree on the opposite bank, he walks x = 1.00 102 m along the riverbank to establish a baseline. Then he sights across to the tree. The angle from his baseline lo the tree is = 35.0 (Fig. P1.53). How wide is the river? Figure P1.53
