a ship moves through the water at 30 miles/hour at an angle of 30° south of east. the water is moving 5 miles/hour at an angle of 20° east of north. identify the ship's vector, the water current's vector, and the vector representing the ship's actual motion.

Step-by-step explanation:

Resultant R of the two vectors is

Where is the angle between Two vectors which is 100^{\circ}[/tex]

R=29.544 miles per hour

and it makes an angle with 30 miles/hr vector

i.e.it makes an angle of 20.538 South of east with horizontal

eve and marks ratios are equivalent

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
