Question

plzzz frnd ans me soon to do this problems (R=S×L)by(A) it is the hint plzzz frnds give me a proper ans plzzz​

Answer 1

Answer:

firstly u mark me as brainlist

Answer 2

Answer:

(1) 5.05 × 10^(-2)Ω

Step-by-step explanation:

R = s × l / A

A = π r^2

(1) s = 1.59 × 10^(-8)

l = 1

r = 0.1 mm = 0.1 × 10^(-3) m

now...

R = [ 1.59 × 10^(-8) ] × 1 / [ π × 0.1 × 10^(-3)^2 ]

R = 1.59 × 7/22 / 0.1 × 10^(-8+6)

R = 1.59 × 7/22 × 10 × 10^(-2)

R = 1.59 × 7/22 × 10 × 1/100

R = 0.0505.....

R ~ 5.05 × 10^(-2)Ω

now u try remaining....
