The density of a floating body can be determined by tying weights to the body until both the body and the weights are completely submerged and then weighing them separately in air. consider a wood log that weighs 1400 n in air. if it takes 34 kg of lead (ρ = 11,300 kg/m3) to completely sink the log and the lead in water, determine the average density of the log. the average density of the log is 821.54 kg/m3.
