Hey it would be true i had the same question on a test
Answer:
200 petals
Proportionality is 50
R = ?
L = 3.1 m;
r = 1.7 mm/ 2 = 0.85 mm = 0.85 * 10^(-3) m
Resistivity of copper ( rho ) = 1.68 * 10 ^(-8) [Ohm m ]
A = 3.15 * ( 0.85 * 10^(-3))^2 = 2.26865 * 10 ^(-6)
R = ( Rho ) * L / A = 1.68 * 10^(-8) * 3.1 m / 2.26865 * 10^(-6) =
= (1.7 * 3 .1 / 2.26865 )* 10^(-2) = 0.02323 Ohms ( the resistance )
Answer:
A is the answer
Step-by-step explanation:
(0, -5):
-5 = 2(0) - 5 >>> -5 = -5
-5 = (0)^2 - 5 >>> -5 = -5
(2, -1):
-1 = 2(2) - 5 >>> -1 = 4 - 5 >>> -1 = -1
-1 = (2)^2 - 5 >>> -1 = 4 - 5 >>> -1 = -1
