Consider the vector b⃗ b→b_vec with length 4.00 mm at an angle 23.5∘∘ north of east. What is the y component bybyb_y of this vec

Stells [14]

Answer:

$\large\boxed {1.59 mm}$

Explanation:

<u>1. Given vector:</u>

length: 4.00 mm = magnitude of the vector
angle: 23.5º north of east = 23.5º from the x-axys (counterclockwise)

<u>2. y-component</u>

The y-component may be determined using the sine ratio, the angle from the x-axys (counterclockwise direction), and the magnitude of the vector.

sine (23.5º) = y-component / magnitude

y-component = magnitude × sine (23.5º) = 4.00 mm × sine (23.5º) = 1.59 mm.

$\large\boxed{y-component = 1.59 mm}$

How can I show money as a fraction?

abruzzese [7]

You can show money as a fraction by taking the amount of cents, and putting it over 100.

Ex. $1.47 = 147 cents
147 cents = 147/100 in fraction form.
