Scurrilous con artists have been known to represent gold-plated tungsten ingots as pure gold and sell them to the greedy at prices much below gold value but deservedly far above the cost of tungsten. With what accuracy must you be able to measure the mass of such an ingot in and out of water to tell that it is almost pure tungsten rather than pure gold?

When you are swimming at the bottom of a pool, the water above and around you exerts force on your eardrum. Calculate the force (in N) exerted on your eardrum when you are at the bottom of a pool that is 5.0 m deep. Assume that the area of your eardrum is 1 cm^2 and the density of water is 1000 kg/m^3 (10,000 cm^2 = 1m^2) (Ans: 5N) To solve this, which of the following equation/s should you use (check as many that best applies) O Q = mL O F1_ F2 A1 A2 O F=ma O A1V1= A2V2 O fEdA = denc €0 Ο ΔL αLo Δ .

The sonar unit on a boat is designed to measure the depth of fresh water (p = 1.00 x 103 kg/m³, Bad = 2.20 x 109 Pa). When the boat moves into salt water (p = 1025 kg/m³, Bad = 2.37 x 109 Pa), the sonar unit is no longer calibrated properly. In salt water, the sonar unit indicates the water depth to be 8.87 m. What is the actual depth (in m) of the water? Number i ! Units m
