Given

The Sun is d=150 million kilometers away from Earth.

Light travels at v=3 × 10^5 m/s.

To find

How long does it take for light to reach Earth from the Sun?

Explanation

We know

Time taken is given by

\begin{gathered} t=\frac{d}{v} \\ \Rightarrow t=\frac{150\times10^6}{3\times10^5} \\ \Rightarrow t=500sec \end{gathered}

Conclusion

The time taken is D.500 sec

Issac and Blaise decide to race. They both start at the same position at the same time. Issac runs at 2m/s but decides to take a
FromTheMoon [43]

Let the Blaise runs for time "t" to complete the race

so the total distance he moved is given by

d_1 = 1* t

Now Issac runs for time t = "t - 2*60"

because it took rest for 2 minutes

d_2 = 2*(t - 120)

now it is given that Blaise wins by 10 m distance

d_1 - d_2 = 10

1* t - 2*(t - 120) = 10

t - 2t + 240 = 10

t = 230 s

now the distance moved by Blaise is given by

d_1 = 1*230 = 230 m

Hey!!

here is your answer >>>

We know that, acids and strong bases are good conductors of electricity!. And gold conducts electricity , while the best is silver and niext comes gold!. And H20 which is water contains less ions , so it is not a good conductors , it is a conductors but not a good conductor!. Salt in it's solid for cannot produce ions, hence, it cannot conduct electricity , but when this salt is mixed with water or when it is in it's molten state it can conduct electricity!. So now,the answer for the question is ,

B) III and IV only!.

Hope my answer helps!

You are asked to burn gas using a Bunsen burner in order to boil water. Which of the following has no mass?
trapecia [35]

-- There is nothing on the list of choices that you provided that has no mass.

-- There are no "things" that have no mass.  Every sample of a liquid, a gas,
or a solid has mass, even if it's only an atom or two. 

I think the only possible items you could name that have no mass would be
spiritual, conceptual, or sensory ones, like maybe ...

-- idea
-- conviction
-- belief
-- concept
-- image
-- sound
-- illusion
-- impression
-- agreement
-- inclination
-- tendency
-- sparkle
-- tingle
-- pain

Things like that.
