The color of an object we see is determined by the

1 answer:

7 0

Answer:

An object appears white when it reflects all wavelengths and black when it absorbs them all. Red, green and blue are the additive primary colors of the color spectrum. Combining balanced amounts of red, green and blue lights also produces pure white.

If vx = 0.40 meters/second and vy = 3.00 meters/second, what is the value of θ?

cestrela7 [59]

<span>θ is the angle whose tangent is 3/0.4 = arctan (7.5) = 82.4°

(That's the angle above the horizontal. If that doesn't match
the </span><span>θ in your diagram, too bad ! For some strange reason,
I wasn't able to see your diagram.)

PLEASE HELP!!

astraxan [27]

Answer:

Explanation:

$\lambda\\$ = v/f

^That is the formula we are going to use.

Now, we were given the speed (v), which is 20.

Now we need to find frequency, in order to solve for the wavelength.

Frequency is the amount of waves in a fixed unit of one second, meaning our F value is the value of 5 divided by 4.

5/4 = 1.25

Therefore our F is 1.25

Now lets plug it in

$\lambda\\$ = v/f

$\lambda\\$ = 20/1.25

$\lambda\\$ = 16

Conversion:

$\lambda\\$ = 8
