Answer:

\(d=1.08\times 10^{9}\ km\)

Step-by-step explanation:

Given that,

Speed of light in vacuum, \(v=3\times 10^8\ m/s\)

Let d is the distance a pulse from a laser beam travels in exactly 1 hour, t = 3600 s

We can find the distance using the formula as :

\(d=v\times t\)

\(d=3\times 10^8\ m/s\times 3600\ s\)

\(d=1.08\times 10^{12}\ m\)

or

\(d=1.08\times 10^{9}\ km\)

So, the distance covered by a  pulse from a laser is \(1.08\times 10^{9}\ km\). Hence, this is the required solution.

  • The distance is the equality and dignity of an object's journey.
  • The distance from the original to the last place of the object is shorter.
  • It is a scalar number and the quantity of the vector.
  • This is a numerical measure of the number between objects or points.
  • It can relate to an evaluation or a physical length depending on certain criteria.

Using formula:

\(\to \bold{d=v\times t}\\\\\to \bold{v=3\times 10^8 \ \frac{m}{s}}\\\\\to \bold{t=1 \ hours}\\\\\)

Convert hours into second:

\(\to \bold{t=1 \times 60 \times 60= 3600 \ second}\)

Putting the value into the distance formula:

\(\bold{= 3.00 \times 10^8 \times 3600}\\\\\bold{= 108 \times 10^{10} }\\\\\bold{= 1.08 \times 10^{12}\ m }\\\\\)

Converting meter into kilometers:

\(\bold{= 1.08 \times 10^{9} \ km}\\\\\)
