You point a laser at a building and send a pulse of light to it. the light reflects off the building and arrives 1.827 × 10^-6 seconds after you sent the pulse out. how far away is the building

Distance, d = 274.05 meters

Explanation:

It is given that,

The time taken by the laser light to reflect off the building and arriving is,

We need to find the distance between the building and you. Let the distance between the person and the building during thee process of reflection and come back is 2d. So,

The speed of light is c is calculated as :

d = 274.05 meters

So, the building is 274.05 meters far from you. Hence, this is the required solution.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
