Physics students use a spring scale to measure the weight of a piece of lead. The experiment was performed two times, one in air and the other in water. If the volume of lead is 50 cm3, what is the difference between two readings on the scale? Density of water is equal to 1000 kg/m³Group of answer choices500 N0.5 N5 N50 N

Use the worked example above to help you solve this problem. A bargain hunter purchases a "gold" crown at a flea market. After she gets home, she hangs it on a scale and finds its weight to be 7.99 N (Figure (a)). She then weighs the crown while it is immersed in water, as shown in Figure (b), and now the scale reads 7.00 N.What is the density of the crown? kg/m3Is the crown made of pure solid gold?YesNo

A large container of water is placed on a set of scales which initially read 0.500 kg. The container has a overflow spout that can be used to collect any overflow into a second container.The second container is also on a set of scales and is initially empty. The second set of scales initially read 0.065 kg.A small ball is lowered into the large container, displacing water down the overflow spout and into the second container.The readings on both scales are now 0.585 kg and 0.100 kg respectively.What is the density of the ball? (to 2 s.f and in kg m−3)(ρwater = 1000 kg m−3)
