a 100.0 m long rod with a diameter of 3.0 mm has a charge of 1028 c. what is the approximate electric field 4 mm from
A small ball is attached to one end of a spring that has as an unstrained length of .200m. The spring is held by the other end, and the ball is whirled around a horizontal circle at a speed of 3.00 m/s. The spring remains nearly parallel to the gr..
Observe the trajectory of a ball thrown into the air with a goal of distance and caught at the same height from which it was tossed. What biomechanical principles do you observe and how do they contribute to the goal of the motion?
