You should first break up all the distances and directions into vectors and then add all horizontal vectors and verticle vectors.
He goes, 5 + 1 m east = 6m East
3 m north
displacement = root(6^2 + 3^2) = 6.708m
direction = arcTan(verticle/horizontal) = arcTan(3/6) = 26.565 degrees
Answer:
The angular frequencies of all the 3 pendulums shall be same.
Explanation:
The time period of a simple pendulum with the approximation 
is given by:
The angular frequency 
is given by
As we can see that the angular frequency is independent on the initial angle (valid strictly for small angle approximations) we conclude that the angular frequencies of the 3 pendulums are the same.
The difference between them is in regard to what spins and what is fixed. In an alternator<span>, electricity is produced when a magnetic field spins inside the stator (windings of wired) </span>
I can’t see the picture what do you need help with
The best answer is b - span.
A span is the distance between two bridge supports The supports may be towers, columns, or even the wall of a canyon.
There are many kinds of bridges but they all fall into three types namely beam, arch and suspension. The major difference between these three kinds of bridges is the distance that each can cross in a single span.
For example, a modern beam bridge is likely to span a distance of 200 feet, a modern arch can span 800 or 1000feet, and a modern suspension bridge can span up to 7000ft.
