The two principal parts of an AC induction motor are the stator and the rotator.
Hope this helped! (:
Answer:
Explanation:
a )
59° south of west means (180 + 59 )° counterclockwise from the +x-axis.
so angle θ = 239 ° .
r = 3.5 miles .
polar coordinates ( r , θ )
= ( 3.50 , 239° )
As the smallest positive angle in degree is 26 then 26 x 9 = 234
so rounding off 239 to 234 , the angle will be 234
polar coordinates ( 3.50 , 234 )
b )
Cartesian coordinates (in miles) for the same point
x coordinate = r cosθ = 3.5 cos 234 = - 2.06 mi
y coordinate = r sinθ = 3.5 sin 234 = - 2.83 mi
mass lol ion kno man can i have the answer choices
Answer:
Total distance = 6.5 km
Explanation:
Let the distance be denoted by the vectors drawn from A, B, C, D, E, and F.
Then the distance covered can be calculated by adding the vectors in the direction given.
Total distance = 3km + 1km+ 1.5km+ 0.5km+ 0.5km
Total distance = 6.5 km
If we were to find the displacement ( shortest distance) then the head to tail rule would be applied using the vectors.
