Aplane is sitting on a runway, awaiting takeoff. on an adjacent parallel runway, another plane lands and passes the stationary plane at a speed of 40 m/s. the arriving plane has a length of 40 m. by looking out the window (very narrow), a passenger on the stationary plane can see the moving plane. for how long a time is the moving plane visible?

1 second

Explanation:

This is a simple calculation involving speed, distance and time. What needs to be calculated is the time it takes for the plane to move through one point in space, and this can be calculated by using the information given in the question (the length of the plane is 40 m, and it is traveling at 40 m/s).

Calculation:

t(time) = d(distance) / s(speed)

t = (40 m) / (40 m/s)

t = 1 second

It would take one second for the plane to move through one point in space, from the tip of its nose to its tail. This calculation makes sense, because logically, if an object travelling at 1 m/s, passes a point in 1 second, logic would dictate that the object is 1 m in length. The same principle applies to this question.

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.

it would be c. predictability
