RED colour of light you should look for if you wanted to see a star behind the interstellar cloud.

In our galaxy and other galaxies, an interstellar cloud is often a buildup of gas, plasma, and dust. In other words, an interstellar cloud is a portion of the interstellar medium (ISM), the matter and radiation that is present in the space between star systems in a galaxy, that is denser than typical.

Interstellar dust has an extremely saturated orange to brownish-red tint that turns saturated red when there is a modest quantity of hydrogen emission.

The graph below represents the relationship between the force exerted on an elevator and the distance the elevator is lifted.
Stella [2.4K]

I have three problems with this question.

#1). If you copied the question exactly the way it's written,
then the question is written very badly.  The wording is
misleading, and the more you try to think about it and
puzzle it out, the more it'll damage your understanding
of Physics.

There is no relationship between the force exerted on an
elevator and the distance the elevator is lifted.

-- If the force is anything more than the weight of the elevator ...
even one ounce more ... then it'll lift the elevator as high as
you want. 

-- If the force is anything less than the weight of the elevator ...
even one ounce less, then that elevator is headed for the bottom.

#2).  You didn't post any graph below, so if we need the graph
to answer the question, then we can't answer the question.

#3).  I guess that's OK, because you didn't ask any question.

What does EMR tell us about wavelength, amplitude, and frequency?
Georgia [21]

Answer:

Amplitude is one-half the height of the wave from peak to trough. Wavelength and frequency are inversely proportional: As the wavelength increases, the frequency decreases.

I hope this helps in a way...

At the instant the traffic light turns green, an automobile that has been waiting at an intersection starts ahead with a constan
Aloiza [94]

Answer

given,

Initial speed of the car = 0 m/s

acceleration of car = 2.4 m/s²

Speed of the truck = 15.5 m/s

to car to overtake the truck distance travel by both should be same

distance traveled by the truck

d = 15.5 t

distance traveled by the car

d = u t + 1/2 gt ²

d = 0.5 x 9.8 t²

now, equating both the equations

15.5 t = 4.9 t²

t = 3.163 s

Time taken by car to overtake truck is 3.163 s

distance travel by the car = 15.5 x 3.163

d = 49 m

b) Speed of the automobile

using equation of motion

    v = u + at

    v = 0 + 2.4 x 3.163

    v = 7.59 m/s

Speed of the automobile while crossing truck is equal to v = 7.59 m/s
