Answer: A: a ray of visible light  

Explanation:

Light is an electromagnetic radiation. It can travel through vacuum as well as medium. The speed of light is maximum in vacuum i.e. 3 × 10⁸ m/s. From experiments, scientists know that nothing can exceed the speed of the light i.e this speed of light is the upper limit and o particle or wave can travel with speed greater than this. Thus, a ray of visible light would have the greatest speed when observed by an astronaut.

Discuss why the article says the fact that we’re in our universe complicates our understanding of the expansion of the universe.
MArishka [77]
<span>Because of our perception of the universe from inside the universe, we are unable to see how and towards what the universe is expanding. Also, our understanding of it is further complicated because we are moving as part of the expansion, thus distorting our perception of it.</span>

PLEASE HELP!!!!!!! MT TIME FOR MY TEST IS ALMOST OVER!!!
pav-90 [236]

Answer:

50 N

Explanation:

Let the natural length of the spring = L

so

100 = k(40 - L)       (1)

200 = k(60 - L)       (2)

(2)/(1):   2 = (60 - L)/(40 - L)

60 - L = 2(40 - L)

60 - L = 80 - 2L

2L - L = 80 - 60

L = 20

Sub it into (1):

100 = k(40 - 20) = 20k

k = 100/20 = 5 N/in

Now

X = k(30 - L) = 5(30 - 20) = 50 N
