5. A simple machine called a block and tackle might be used:
a. by a high school football team.
b. to transfer energy making it easier to do work.
c. to demonstrate how pulley systems are only efficient in moving small objects.
d. to demonstrate the mechanical advantage of a fixed pulley.
e. none of the above.

6.When moving an object, mechanical advantage would be classified as:
a.the object being relocated.
b.the shorter the distance, the less work involved to complete the task.
c.knowing how a machine operates.
d. a ramp.
e. Work=Force X Distance.

7. As you study an atlas describing regions of Queensland, you determine the geography/climate of the Palmer River region was important to gold miners because:
a. It was close to Cooktown, the port of entry into Australia.
b. The Palmer River region is full of quartz.
c. Climate in the winter is mild.
d. It was not difficult to transport crushing batteries to the mining site.
e. Location of the region and its weather determined where gold might be located and the months that miners could work the area.

8. It is important to be able to measure the earth using latitude and longitude because:
