consider a calorimetry experiment where 0.500 kg of lead at 100 degree is placed in 0.200 kg of water 20 degree that was contained in an aluminum calorimeter with mass of 0.400 kg and specific heat of 9.0 x 10 J

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
