Answer:
14 ohms
Step-by-step explanation:
The resistance varies directly with length, so increasing the length by a factor will increase the resistance by the same factor.
__
The length of the wire increased by a factor of 1.4 from 100 ft to 140 ft. That means the resistance will increase by a factor of 1.4 from 10 ohms to 14 ohms. (The diameter did not change.)
The longer wire will have a resistance of 14 ohms.
Answer: -3/10
Step-by-step explanation: A positive and a negative will subtract.
1. Find the common denominator (8/10)
2. simce 8/10 is greater than 1/2 you need to add a negative to get 8/10 a lower value
3. subtract 5/10 or 1/2 from 8/10 to figure out what gives you the correct answer
(-2x+10Y)(4X-6Y) can be simplified as -8x+-60Y because you have to combine like terms such as -2x and 4x.
Answer:
the answer is 22 units,hope it helps
The answer is the square root of 23 i.
(The “i” is outside of the square root symbol, and the 23 is positive).
Hope this helps! (:
