Answer:
A. 23/30
Step-by-step explanation:
2/3+1/10
Find the LCM (Least Common Multiple):
20/30+3/30 = 23/30
No nothing can go into 7 evenly except 7 but that doesn’t go into 20 evenly so your answer is no
Since they are just next to each other ill take it multiplication and that would be 128 if its not let me know and ill correct it
9514 1404 393
Answer:
0.261 ohm
Step-by-step explanation:
If the radius increases by a factor of 0.7/0.4= 7/4, the square of this factor is (7/4)^2 = 49/16. The inverse of this square is 16/49, which is the factor by which the resistance changed.
The resistance of the larger wire is ...
(16/49)(0.80 ohm) ≈ 0.261 ohm
