What is the mass of the cube? 64 g 4.0 g 1.0 g 16 g 2 / 5 2) A solid triangle made from copper is cut into three pieces P, Q and R. Which has the greatest density? pieces P and R only all pieces have the same density piece Q only piece P only 3 / 5 3) An object that has a mass of 15 kg on the Earth is taken to the Moon. The gravitational field strength on the Earth is 10 N/kg and on the Moon is 1.6 N/kg. What are the mass and the weight of the object on the Moon? mass: 15 kgweight: 24 N mass: 15 kgweight: 150 N mass: 150 kgweight: 24 N mass: 24 kgweight: 15 N 4 / 5 4) A spacecraft is in orbit around the Earth. Why do the astronauts appear weightless? In space their mass becomes zero. They are falling at the same rate as the spacecraft. In space their inertia becomes zero. They are outside of the earth's gravitational field. 5 / 5 5) Consider the following statements: (1) Inertia is a force in the direction of the motion. (2) Inertia is the tendency of an object to maintain its motion. (3) The more mass an object has, the greater its inertia. Which of the statements(s) is/are correct? (2) only (2) & (3) only (1) only (1) & (2) only Your score is Restart quiz
