Does it take 2 or 250 people to control the space shuttle launches?

It takes 250 people to control space shuttle launches because a variety of different people are needed to execute the job from engineers to technicians and tons of other specialized people.

Hope this helps!   :)

Explanation:

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
