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...
The amount of debris expected to reach the surface of the Earth, the size of the impact area expressed in square metres and how such data were calculated; 预计到达地球表面的碎片数量、以平方米表示的撞击面积大小和这些数据的计算方法; UN-2 The storage cost was estimated by De Dietrich to ...
All input parameters are summarized in Table S1. First, the light interception per square meter per face (W/m2) was simulated. After simulations, the daily light interception per unit area (DLI; Eq. 4) was calculated. (4)DLI=∫t=618∑i=1msi∗LFidtSwhere LFi is the captured radiation...
meters. This allows you to find a reference elevation pertaining to a spot on the map close to or within the area you'll explore. After all, knowing how steep or flat a place is gives only part of the story; you probably want to now how "high" or "low" you are in absolute terms...
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...
A body falling from rest covers distances s1 and s2 in the first and second seconds respectively. Calculate the ratio s1/s2. Free Fall Motion: When an object is released freely in the air, the object follows the free fall motion due to th...
Calculate work done by gravity on the land. A plank of length L = 2 m and mass M = 3 kg sits atop two scales that are fixed to the ground. Scale 1 is at the left end of the plank and scale 2 is...
