Answer:
Explanation:
We shall express each displacement vectorially , i for each unit displacement towards east , j for northward displacement and k for vertical displacement .
14 m due west = - 14 i
22.0 m upward in the elevator = 22 k
12 m north = 12 j
6.00 m east = 6 i
Total displacement = - 14 i + 22 k + 12 j + 6 i
D = - 8 i + 12 j + 22 k
magnitude = √ ( 8² + 12² + 22² )
= √ ( 64 + 144 + 484 )
= √ 692
= 26.3 m
Net displacement from starting point = 26.3 m .
The phrase "light year" is a <u><em>distance</em></u> ... it's the distance that light travels through vacuum in one year.
When you look at an object located 1 light year away from you, you see it as it was 1 year ago.
If a star located 10 light years away from us suddenly brightens, or dims, or explodes, we see the event <em>10 years later.</em>
Answer:
Pilots depend on the precision of INSTRUMENT LANDING SYSTEMS to guide them when they have limited visibility.
Explanation:
A pilot is a professionally trained individual that has the ability to control an aircraft following directions from a flight control.
Instrument landing system is a guidance system that makes available an instrument based procedures for guiding the pilot of an aircraft to approach and land safely. This system guides the pilot during unfavorable conditions such as low visibility through the use of radio signals.
There are two types of guidance provided by this system:
-> Lateral guidance subsystem and
-> Vertical guidance subsystem.
Lateral guidance subsystem prevents the aircraft approaching a runway to shift laterally from the path recommended.
Vertical guidance subsystem prevents the aircraft approaching a runway to shift laterally from the recommended path.
I think you meant to say "procedure" instead of "produced".
Choice B is the answer as it is the safest and most sensible (to prevent damage to clothing or start a fire for example). The other choices are nonsensical or silly.
