You probably already took this but if anyone wanted to know the answer it's D. "A system where matter and energy cannot enter or leave the system".
(I also took the quiz for it and got it correct)
It's either a comet or asteriod
Answer:
the answer is c
Explanation:
by transferring heat from the tropics to the colder climates
Answer:
The width is 
Explanation:
From the question we are told that
The width of the slit is 
The wavelength of the light is 
The position of the screen is 
Generally angle at which the first minimum of the interference pattern the light occurs is mathematically represented as
![\theta = sin ^{-1}[\frac{m \lambda}{d} ]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20%20sin%20%5E%7B-1%7D%5B%5Cfrac%7Bm%20%5Clambda%7D%7Bd%7D%20%5D)
Where m which is the order of the interference is 1
substituting values
![\theta = sin ^{-1}[\frac{1 *721*10^{-9}}{ 77.7*10^{-6}} ]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20%20sin%20%5E%7B-1%7D%5B%5Cfrac%7B1%20%2A721%2A10%5E%7B-9%7D%7D%7B%2077.7%2A10%5E%7B-6%7D%7D%20%5D)

Now the width of first minimum of the interference pattern is mathematically evaluated as

substituting values


Now the width of the pattern's central maximum is mathematically evaluated as

substituting values


In California, changing lanes in the middle of an intersection D. is legal.
Although it is legal, it's not necessarily the safest thing to do in an intersection.
