Answer:

Explanation:
<u>Speed</u>
The speed is calculated as the ratio of the distance d by the time t:

If we need to calculate the distance, the equation is solved for d:
d=v*t
The speed of light is

It takes t=9.221 seconds for light reflected from the moon Vega to reach planet Xartan.
We can calculate the average distance the light traveled:


Or, in scientific notation:

In case they get affected by it
Answer: the first is gravity
the second is Newton’s 3rd Law of Motion
Hope this helped :)
Explanation:
The thing to do here is to balance the eqns that is to balance the stoichometric ratios or coefficients of the cpds.
hope you understand. all the best.
