I believe it would be orthoclase feldspar, quartz, micas, and amphiboles are the most abundant in granite.<span />
Aquifer- the layer permeable rock that has connecting pores & transmit water freely, the artesian well water rises to the surface.
Hope this helps!
Answer:
E = {(Charge Density/2e0)*(1 - [z/(sqrt(z^2 - R^2))]}
R is radius = Diameter/2 = 0.210m.
At z = 0.2m,
Put z = 0.2m, and charge density = 2.92 x 10^-2C/m2, and constant value e0 in the equation,
E can be calculated at distance 0.2m away from the centre of the disk.
Put z = 0.3m and all other values in the equation,
E can be calculated at distance 0.3m away from the centre of the disk
According to Ohm's law for a portion of the circuit we have:
U=RI=>I=U/R=9/4=2.25 A
