An object hangs from a spring balanceIhe balance registers 29 N in air, 18 N when this object is immersed in water, and 24 N when the object is immersed in another liquid of unknown density. What is the density of that other liquid? Number n Units v What is the minimum area {in square meters) of the top surface an ice slab 0.319 m thick oating on fresh water that will hold up a 1190 kg automobile? Take the densities of ice and fresh water to be 917 kg/m3 and 998 kg/ms, respectively. Number n Units v A 3.00 kg block hangs from a spring. A 380 g body hung below the block stretches the spring 2.80 cm farther. (a) What is the spring constant? (b) If the 380 g body is removed and the block is set into oscillation, nd the period of the motion. (a) Number n Units v (bl Number n Units v
