Answer:

d=2.77\cdot 10^6\ Km

Explanation:

<u>Speed</u>

The speed is calculated as the ratio of the distance d by the time t:

\displaystyle v=\frac{d}{t}

If we need to calculate the distance, the equation is solved for d:

d=v*t

The speed of light is

v=3\cdot 10^5\ Km/s

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:

d=3\cdot 10^5\ Km/s*9.221

d=2,766,300\ Km

Or, in scientific notation:

\mathbf{d=2.77\cdot 10^6\ Km}

Determine tge energy in joules of a photon whose frequency is 3.55x10
JulijaS [17]
E = hf
E = 6.63×10^-34 × 3.55×10 eV
1 eV = 1.60×10^-19 J
E = 6.63×10^-34 × 3.55×10 × 1.60×10^-19
E = 3.77×10^-51 J
