How long does it take light to travel 850 km in a vacuum? Answer in ms.(Express your answer to two significant figures.)

Physics
1 answer:
poizon [28]3 years ago
5 0

Answer:

0.002833 sec

Explanation:

Speed of light in vacuum is 3\times 10^{8}m/sec

Given distance = 850 km = 850×1000=850000 m

We have to calculate the time that light take to travel the distance 850 km

Time T=\frac{distance }{speed}=\frac{850000}{3\times 10^8}=2.833\times 10^{-3}sec

So the time taken by light to travel 850 km is 0.002833 sec

Why is creativity important in constructing specific methods?
Nat2105 [25]

Hi!

The correct option would be C.

<h3>Explanation:</h3>

Scientific method is the protocol in an experiment for a hypothesis that involves testing, measurement, observation and necessary modification of hypothesis during the course of the experiment. There are several manners and experiments that can be tested for the hypothesis, and plenty of ways to design an experiment.

Scientific experiments can be very tricky to design, owing to the numerous parameters and variables that need to be accounted for. Of course, there are some relatively simple experiments. Creativity is needed for all branches of science, because each field presents obstacles in discovery, and creativity allows for us to devise ways around those obstacles. Science has always tested humans ability to think outside the box and question their surroundings, and creativity has been the driving force.

Hope this helps!
