Answer:
9828 coulombs
Explanation:
z = 
Relation between the cartesian and polar coordinates 
x = r cos ∅ 
y = r sin ∅
z =  =
 = 
next we calculate the surface charge density of the cone 
б ( r, ∅ ) = xyz^2 = 3r^4 sin∅ cos∅
Charge given as 
Q = ∫ б(r,∅ )ds
    = ∫ б(r,∅ ) 
after integration
 Q  = ∫ б(r,∅ ) 2dA
Attached below is the remaining part of the solution
 
        
             
        
        
        
Answer:
B
Explanation:
graph b shows a steady pace of movement for 20 minutes and then shows a plateau in the distance, showing that while time keeps moving (obviously), the distance doesn't change. then after 5 minutes, the student gets up and starts running again. hope this helped!
 
        
             
        
        
        
2 -An invasive species is a species that is not native to a specific location (an introduced species), and that has a tendency to spread to a degree believed to cause damage to the environment, human economy or human health.[2]
The term as most often used applies to introduced species that adversely affect the habitats and bioregions they invade economically, environmentally, or ecologically. Such species may be either plants or animals and may disrupt by dominating a region, wilderness areas, particular habitats, or wildland–urban interface land from loss of natural controls (such as predators or herbivores). This includes plant species labeled as exotic pest plants and invasive exotics growing in native plant communities.[3][4][5][6] The European Union defines "Invasive Alien Species" as those that are, firstly, outside their natural distribution area, and secondly, threaten biological diversity.[7][8] The term is also used by land managers, botanists, researchers, horticulturalists, conservationists, and the public for noxious weeds.[9]
        
                    
             
        
        
        
True, recycling allows products to be reused which saves alot the natural resources that are used.
