1. Bowling ball sitting in the rack:
kinetic energy = 0, because the ball is not in motion - we have only potential energy in this case
2. Bowling ball knocking pins down:
at the moment of knocking kinetic energy is increased, while the potential energy is decreased
Answer:
oxygen gains two electron to attain electron configuration like neon. Oe-²
Explanation:
Answer:
<em>The resultant velocity has a magnitude of 38.95 m/s</em>
Explanation:
<u>Vector Addition</u>
Given two vectors defined as:


The sum of the vectors is:

The magnitude of a vector can be calculated by

Where x and y are the rectangular components of the vector.
We have a plane flying due west at 34 m/s. Its velocity vector is:

The wind blows at 19 m/s south, thus:

The sum of both velocities gives the resultant velocity:

The magnitude of this velocity is:


d = 38.95 m/s
The resultant velocity has a magnitude of 38.95 m/s
