Answer:
The tape readings at 104°F will be 449.88 ft by 514.86 ft
Explanation:
Co-efficient of linear expansivity of Steel = α = 7.3 × 10⁻⁶ ft/ft.°F (from literature)
α = ΔL/(L₀(ΔT)
ΔL = change in length = ?
L₀ = original length = 100.0 ft
ΔT = change in temperature = 104 - 68 = 36°F
ΔL = α × (L₀(ΔT))
ΔL = 7.3 × 10⁻⁶ × 100 × 36 = 0.02628 ft = 0.0263 ft
ΔL = Lf - L₀
Lf = L₀ + ΔL = 100 + 0.0263 = 100.0263 ft
This tape is used to measure a dimension of 450 ft × 515 ft,
Meaning, the 450 ft will give a reading of 450 × 100/100.0263 = 449.88 ft
And the 515 ft gives a reading of 515 × 100/100.0263 = 514.86 ft.
The tape readings at 104°F will be 449.88 ft by 514.86 ft
Answer:
A mock-up
Explanation:
It is made of cheap and easy to access parts.
Depending on the age the toy is made for it could teach younger children things such as letters and numbers and for a older kid it could teach them how different things are put in the robot to help it work
Answer:
Clausius inequality is defined as, it applies in the cycle of real engine and there is negative entropy change. When the entropy given in the cycle during the environment is larger than entropy transferred into heat engine from hot reservoir. As, entropy of reversible system are zero.
Clausius Inequality is defined as:
![R_2-R_1> \oint_{T_1}^{T_2}\frac{dQ}{T}](https://tex.z-dn.net/?f=R_2-R_1%3E%20%5Coint_%7BT_1%7D%5E%7BT_2%7D%5Cfrac%7BdQ%7D%7BT%7D)
Where R1 and R2 are not be equal.
