Which of the following statements are true? Because the Earth has mass it produces gravity. There is no gravity at the space station I need to do work to move a satellite from lower to higher orbit. Because the force of gravity is a conservative force and because it acts as a centripetal force it does no work, the mechanical energy of Earth is conserved and it will not crush into the Sun. Since Moon has no air, there is...

Is 1 correct? Can someone explain #2?
QUESTION 1 Which of the following statements about conductive materials is incorrect? 1. Charges in a conductor move in response to an electric field. Examples of conductive materials include iron, aluminum, and gold. 3. Increasing the voltage applied across a conductor will cause the conductor temperature to increase 4 Current flow in a conductive material is due to the movement of positive and/or negative charges QUESTION2 Which of the following statements about voltage...

Which of the following is not correct? Select one: a. Work occurs when a force is applied to an object through so that the object is moved some distance. b. If a force is applied to an object but there is no displacement, then no work is done. c. The work done by gravity is always negative. d. The work done by a constant force is the product of the magnitudes of the parallel component of the force and the...

12. Which of the following does not correctly describe NZ he following does not correctly describe SN2 reactions of alkyl halides? B. Tertiary halides react faster than secondary halides. e or reaction depends on the concentrations of both the alkyl halide and the nucleophie. The mechanism consists of a single step with no intermediates. The transition state species has a penta valent carbon atom.
