000 kilograms of soil was lost over four years, then: Erosion rate equals 30,000 divided by 4, or 7,500 kilograms per year. To compare erosion rates in different land areas, you need to calculate the rates for a unit area, such as one square meter or one acre. Simply divide...
Area = 12,500 squared meter Replychan says: January 26, 2023 at 5:07 pm Assume the average energy density of sunlight to be 800 W/m2 and the overall photovoltaic system efficiency to be 10%. Calculate the land area covered with photovoltaic cells needed to produce 1,000 MW, the size...
Reduce the fraction to a unit area so that the final result is the number of people in one acre or square mile or square meter, for example. Another way to think of this is to carry out the division represented by the fraction. If you wanted to calculate the population density of a t...

have a property called Young's modulus or the elastic modulus Y, which is particular to each material. Higher values signify a higher resistance to deformation. Its units are the same as those of pressure, newtons per square meter (N/m2), which also is force per unit area...
Since 1872, Yellowstone National Park has been protected land with beautiful natural wonders which now attract millions of visitors. However, the park has a huge, terrifying secret: It's an active supervolcano and one of the largest volcanic systems in the world. ...
The Grand Canyon is one of the most iconic landmarks in Arizona, attracting more than 4.5 million visitors every year. While this natural wonder is also one ofthe greatest canyons in the world, it's full of poisonous species, like rattlesnakes and Gila monsters (lizards). Although such cre...
Just like many land creatures travel south to Gulf Coast states for the winter (including humans), some of the marine species in the Gulf of Mexico also migrate to the area during the cooler months of the Northern Hemisphere. But whether they live there or are just visiting, the species th...
