The navigation rules entail vessels restricted in their ability to maneuver to display appropriate flag or lights. During the day of engagement of vessel in diving activities the rigid replica of the international code flag "ALPHA" must be exhibit not less than 3.3 feet while during night time the vessel must display the navigation light which is red and white and this requirement does not affect divers red and white flag which may be required by state to mark a divers location. The "A" flag is a kind of navigational signal which indicates the vessel’s restricted maneuverability and do not pertain to diver.
Since energy can be measured as work, we can write energy = force x distance. Thus SI derived unit of energy has the units of newtons x meter or kg m2/s2.
<em>F</em> = 153 N
Explanation:
Let us define first our directional convention. Anything pointing up or to the right is considered positive and anything pointing down or to the left is considered negative. Now let's look at the components 
and 
:
= 350 N - 200 N = 150 N
= 180 N - 150 N = 30 N
The magnitude of the resultant force <em>F</em> is given by
To find the direction 
, we use
