Total cost (both cars) 3 * 104 dollars
a town has hight schools with 4,000 students each. What is the order of magnitude of the total number of high school students in the town?
Look distance is the total length covered by a body and displacement is the shortest length covered by a body. Also displacement is a vector quantity (has both magnitude and direction) and distance is a scalar quantity (has only magnitude and no direction)
A professional football team averaged 50,000 fans for each of its eight home games. What is the order of magnitude of the total attendance?
figure it out
No. The average speed is the average of the magnitude of the velocity but not the magnitude of the average of the velocity.This is because for vectors |A + B| ≤ |A| + |B|.Suppose you travel 100 metres due East at 10 metres per second and then 100 metres due North also at 10 metres per second. Your speed, throughout, is 10 metres per second and so that is your average speed.But your average velocity is the total displacement vector divided by the total time. This is100*sqrt(2) metres due NE/20 sec = 7.07 metres per second due North East.Its magnitude is 7.07 metres/sec.
Blue jays average from eleven to twelve inches in total length.
I would prefer to use "distance" instead of "length".distance = speed x time

They should be Equal in length. However, the ration of the leg to the total height is about 0.61.
