You are asked to determine the identity of an unknown liquid and can measure only one physical property. you heat the liquid and record that the liquid turns to vapor at 100°c. this demonstrates which physical property? question 1 options: ability to conduct electricity combustibility melting point boiling point

boiling point i took the quiz

vapour or gas assuming atmospheriv pressure

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
