The angle between the two bonds is .106". If the bond length r = 0.107 nm long, locate the center of mass of the molecule. The mass mH of the hydrogen atom is 1.008 u, and the mass m0 ofthe oxygen atom is 15.9999 u, (Use a coordinate system centered in the oxygen atom, with the X-axis to the right and the y-axis upward.

ASK YOUR TEACHER Explorers in the jungle find an ancient monument in the shape of a large isosceles triangle as shown in the gure below. The monument is made from tens of thousands of small stone blocks of density 3 445 kg/m3. The monument is 15.5 m high and 70.0 m wide at its base and is everywhere 3.10 m thick from front to back. Before the monument was built many years ago. all the stone blocks lay on the ground. How much work did laborers do on the blocks to put them in position while building the entire monument?
