A box that weighs 250 N is at rest on the floor. If the pressure exerted by the box on the floor is 10,000 Pa, over what area (in m2) is the box in contact with the floor

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.

A). redi wish i´ve

Heat up ? and cool down? well im guessing at this one, plz check it first

Ithink the answer is 6.0
