Aaron created this chart to list the benefits and limitations of using synthetic polymers. A 2-column table with 4 rows titled benefits and limitations of using synthetic polymers. The first column labeled benefits has entries are flexible, are biodegradable, are lightweight, cost little to produce. The second column labeled limitations has entries add waste to landfills, are difficult to recycle, face a low availability of raw materials, are inexpensive to recycle. In which row has Aaron made an error in his chart?

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
