Answer:

[tex]d=1.08\times 10^{9}\ km[/tex]

Step-by-step explanation:

Given that,

Speed of light in vacuum, [tex]v=3\times 10^8\ m/s[/tex]

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 :

[tex]d=v\times t[/tex]

[tex]d=3\times 10^8\ m/s\times 3600\ s[/tex]

[tex]d=1.08\times 10^{12}\ m[/tex]

or

[tex]d=1.08\times 10^{9}\ km[/tex]

So, the distance covered by a  pulse from a laser is [tex]1.08\times 10^{9}\ km[/tex]. 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:

[tex]\to \bold{d=v\times t}\\\\\to \bold{v=3\times 10^8 \ \frac{m}{s}}\\\\\to \bold{t=1 \ hours}\\\\[/tex]

Convert hours into second:

[tex]\to \bold{t=1 \times 60 \times 60= 3600 \ second}[/tex]

Putting the value into the distance formula:

[tex]\bold{= 3.00 \times 10^8 \times 3600}\\\\\bold{= 108 \times 10^{10} }\\\\\bold{= 1.08 \times 10^{12}\ m }\\\\[/tex]

Converting meter into kilometers:

[tex]\bold{= 1.08 \times 10^{9} \ km}\\\\[/tex]
