5. Which set of listed parameters would result in the greatest number of Gs at the bottom of a
loop (location C)?
a. Height at A = 50.0 m, Height at B = 30.0 m, Radius at C = 20.0 m
b. Height at A = 60.0 m, Height at B = 45.0 m, Radius at C = 20.0 m
c. Height at A = 60.0 m, Height at B = 35.0 m, Radius at C = 25.0 m
d. Height at A = 80.0 m, Height at B = 60.0 m, Radius at C = 50.0 m

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
