sleet_krkn [62]

Answer:

0 meters

Explanation:

When we talk about displacement, think that the think of it as the measure of the distance between the starting point of the object, from its end point.

Since we are talking about a lap around a track, it would mean that the starting point is also the end point. So if you started and end at the same point, the distance between it would be 0.

How much fertilizer is applied each year on lawns throughout the united states?
Stells [14]

Answer:

1.8 pounds  of Nitrogen per year; (based on 1000 square feet per application) for cool season grasses.

Explanation:

The above application shows  an average of 0.9 pounds of inorganic and organic  nitrogen per 1000 square feet per application . Therefore not more than 0.9 pounds of nitrogen will be needed  per application.And for a whole year 1.8 pounds of Nitrogen per year will be needed.

This calculation was based on 1000 per square.But most lawn are not 1000 per square, therefore calculation can be done using the 1000 per squares as the  reference point .

AMMONIA and its solutions, AMMONIUM NITRATE AND UREA  (which is organic source)<u>are the sources of this Nitrogen</u>.

Urea is non -explosive in nature and solid. However, ammonia and ammonium Nitrate are both explosive.
