Each year, about percent of the arctic sea ice moves south into the greenland sea, where it eventually breaks up and melts away.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

The answer is 12, for the points

Answermake them get very hot and over time wear them out;

D.) a wheel barrow, due to the fact that where the weight is in the middle, the fulcrum is at the wheel, and the input force is at the other end
