Uestloh 1 Which is taller, a 20ft giraffe or a 240 inch pole? (Show your conversion

Height of pole = Height of giraffe

Explanation:

Given:

Height of giraffe = 20 ft

Height of pole = 240 inch

Find:

Which is taller

Computation:

Height of giraffe = 20 ft

We know that 1 ft = 12 inch

So,

Height of giraffe = 20 × 12 inch

Height of giraffe = 240 inch

and

Height of pole = 240 inch

Height of pole = Height of giraffe

Uncertainty ΔV = 22.601 x 10^-10

ΔV = 2.2601nv or 2.2601 x 10^9V

Explanation:

from V = kQ/r

Uncertainty in V is given by δV = V square root [ (δQ/Q)^2 + (δr/r)^2]

ΔV = V square root [ (ΔQ/Q)^2 + (Δr/r)^2] (2)

Given that ; Q = 3.2042e−19 C, r = 0.08 m, ΔQ = 1.6021e−21 C, Δr = 0.005 m

Plugging the values given into equation (2)

from ΔV =(kQ/r) square root [ (ΔQ/Q)^2 + (Δr/r)^2]

ΔV = 9 x 10^9 x 3.2042e−19 / 0.08 square root [ (1.6021e−21/ 3.2042e−19)^2 + ( 0.005/0.08)^2]

ΔV = 360.47 x 0.06269 x 10^-10

Uncertainty ΔV = 22.601 x 10^-10

ΔV = 2.2601nv or 2.2601 x 10^-9V
