A defibrillator passes 14.29 A of current through the torso of a person for 8 ms. How much charge moves (in Coulombs)

q=0.11432 C

Explanation:

Given that

Current ,I= 14.29 A

Time ,t= 8 ms= 8 x 10⁻³ s

We know that ,The relationship between current and time is given as

t=time

q=Charge

I=Current

q= I t

Now by putting the values in the above equation we get

q= 14.29 x 8 x 10⁻³

q=114.32 x 10⁻³  C

q=0.11432 C

Therefore the charge will be 0.11432 C.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

i had this question and the answer was 3.15 miles.
