The ethical "no free lunch" rule states that: if something someone else has created is useful to you, it has value, and you should assume the creator wants compensation for this work. if an action is not right for everyone to take, it is not right for anyone to take. one should take the action that produces the least harm or incurs the least cost. one can put values in rank order and understand the consequences of various courses of action. if an action cannot be taken repeatedly, then it is not right to be taken at any time.

 If something someone else has created is useful to you, it has value, and you should assume the creator wants compensation for this work

Explanation:  This "no free lunch" rule implies that every thing or service is created by someone and as such is the property of someone, unless otherwise stated. This again means that if something is someone's property then compensation should be made for something useful that we have received from that creator, at least he expects it, as we do to make something and in return receive satisfaction in the form of compensation.

the answer is: c. c.it limited the president’s power to start wars.

the war powers resolution of 1973 requires the president to notify the congress whenever the president wanted to order a military operation to other countries within 48 hours. if after being reviewed the congress disagree with the proposal, that the president will be banned from ordering the operation.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
