A long, nonconducting cylinder (radius = 6.0 mm) has a nonuniform volume charge density given by αr2, where α = 6.2 mC/m5 and r
erastovalidia [21]

Answer: 2.80 N/C

Explanation: In order to calculate the electric firld inside the solid cylinder

non conductor we have to use the Gaussian law,

∫E.ds=Q inside/ε0

E*2πrL=ρ Volume of the Gaussian surface/ε0

E*2πrL= a*r^2 π* r^2* L/ε0

E=a*r^3/(2*ε0)

E=6.2 * (0.002)^3/ (2*8.85*10^-12)= 2.80 N/C

Which of the following best explains why clear-cutting forests is more destructive than selectively cutting down trees in forest
garri49 [273]
<span>The answer is a. cutting trees reduce fertility and eliminates animal habitats. Plant material is essential in maintaing soil fertility. Leaves and branches decay to form humus; removing trees decreases the organic content. Trees are home to many animal species, including birds, insects and amphibians. Some trees are even support or home to other plants. Examples include epiphytes in the rainforest ecosystem. Clear cutting forests disrupts whole communities and ecosystems. </span>

Is P4O8 a ionic or covalent compound??
tresset_1 [31]

Salt is made up of sodium and chloride and is ionically bonded. Sugar, on the other hand, is composed of carbon, oxygen, and hydrogen and has covalent bonds. A salt molecule is made up of one sodium atom and one chlorine atom. For salt to be made, the sodium atom must lose an electron and become a sodium ion.
