8 0

Answer:

Option (4)

Explanation:

Here, Speed of light= 3\times10^5 Km/sec

Distance= 1.5\times10^8 Km

We know that,

Speed=\frac{Distance}{Time}

\implies Time=\frac{Distance}{Speed}

Time=\frac{1.5\times10^8}{3\times 10^5}

=0.5 \times10^3

=500 sec

=8 minutes 20 sec

Hence, the correct answer is option (4) i.e 8 minutes.

Which is the most ethical response if an experiment fails to confirm a hypothesis?
miv72 [106K]
In this circumstance one should revise the hypothesis and develop a new experiment to test it.An example could be the theory of Agraham Gottloeb Werner that all rocks were precipitated from water including not just sedimentary rocks but also volcanic, plutonic and metamorphic rocks. The more the earth was studied, especially by James Hutton in Scotland, the more it became obvious that granites for example were deposited in a molten state, thus disproving that hypothesis or theory.
