students in ms. delgado’s science class built machines. they measured the input and output forces. the results of four students are listed in the table.

which lists the students in order from student whose machine has the least mechanical advantage to student whose machine has the greatest mechanical advantage?

brian, dipak, aida, lian
lian, dipak, aida, brian
brian, lian, aida, dipak
lian, aida, dipak, brian

Lian, Aida, Dipak, Brian

Explanation:

The mechanical advantage of a machine is defined as the ratio of the output force to the input force.

Brian,

Lian,

Dipak,

Aida,

So, form above data it is clear that the mechanical advantage of Lian's machine is least while Brian's machine is greatest.

Hence, the correct order is (d) " Lian, Aida, Dipak, Brian  ".          

the answer is b ) square root of 5

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
