From the theory we know that:
c = λ / T
f = 1 / T
Where:
c = 3.
/ m (the speed of light)
λ is the wavelengh (in meters)
T is the period (in seconds)
f is the frequency (in Hz)
We were told that:
f = 7.30 . 
And we want to find out the value of λ.
c = λ / T
c = λ . 1/T
Swaping 1/T = f
c = λ . f
λ = c / f
λ = 3 . / 7.30 .
λ = 4.12 
m
Response: 4.12 m = 412 nm

Answer:
indirect sunlight
Explanation:
we're receiving some sunlight, but not much, if it's winter in one place, it's summer in another
Answer:
In the second case there's no way to know what depth the bullet will penetrate into the block.
Explanation:
Since the block is on a <em>frictionless </em>surface, when hitted by the bullet, this last one could barely penetrate the surface of the block and, both, start moving as one (<em>perfectly inellastic collition</em>) since here, there's no vise to hold the block into place.
Ok. what rock tho. cause all the rocks i have is all bleh and boring
