Answer:
Since the maximum thermal efficiency is higher than 55 percent, there can be a power cycle with these reservoir temperature with an efficiency higher than 55 percent.
Explanation:
The maximum thermal efficiency is determined from the given temperature
nth Carnot = 1- TL/TH
Where TL= 17+273= 290k
TH= 627*273= 900K.
nth Carnot = 1- 290/900 = 0.68
0.68*100 = 68 percent
The answer is "positive" because a vector can be represented by an arrow. An arrow or "vector" can be denoted by drawing the size of the arrow in proportion to the magnitude of the vector. The positive and negative are designated for direction...
Good luck -Abi :)
Answer:
0.04 m
Explanation:
The harmonic is given by λ = 2L/n were L= length of guitar string = 1.75 m and n = harmonic = 78.
So, λ = 2L/n = λ = 2 × 1.75 m/78 = 0.044 m ≅ 0.04 m
