Answer:
Ask your Teacher if you are missing any work and if you are do it and do some things for extra credit
Step-by-step explanation:
The electrical resistance of a wire varies as its length and inversely as the square of the diameter.
R = (k*L)/(d^2)
where k = proportionality constant
Since the two wires have the same material, their proportionality constant is same.
Equating that
(R1*d1^2)/L1 = (R2*d2^2)/L2
Given that R1 = 10 ohms, d1 = 1.2 mm or 0.0012 m, L1 = 18 m, d2 = 1.5 mm or 0.0015 m, L2 = 27 m, and R2 is unknown.
Therefore
[10*(0.0012^2)]/18 = [R2*(0.0015^2)]/27
R2 = 9.6 ohms
Answer:
No
Step-by-step explanation:
202 hundredths is equivalent to 0.202.
Starting from left, 0 is in unit place, 2 is in Tenths place, 0 is in Hundredths place and 2 is in thousandths place.
The value of 2 (at left, just after decimal) is 1/10
The value of 2 (at right,) is 1/1000
It means, 202 hundredths is equal to 2 tenths and 2 thousandths. Hence, the given statement is not correct.
Answer:
yes
Step-by-step explanation:
its correct because divide by 2/ 28/16=14/8
