Answer:
Implements a reordering of the letters of the alphabet.
Explanation: GIVE ME 5 STARS AND a HEART!!! Those contacts are wired across the rotor so that each contact on the left connects to the contact on the right in some scrambled arrangement. Each rotor, therefore, implements a reordering of the letters of the alphabet, which mathematicians call a permutation.
Answer:
Explanation:
Given: Pressure of a fluid column ΔP=ρgΔh
Density of water (ρ) = 1000 kg/m^3
Acceleration of gravity (g) = 9.8 m/sec^2
Δh = difference in height / elevation of water tower and tap
= 50 - 10
= 40
Substitute back into equation:
Pressure = 1000*9.8*40
= 392000 N/m^2
The answer is D.
Answer:
C. Low viscosity for Maine in the winter and high viscosity for Florida in the summer.
Explanation:
The choice of motor oil or engine oil depends on the type of engine and also on the type of climate on which the engine runs.
In winter climates, we should use oil with low viscosity as at lower temperatures, the it flows more readily if its viscosity is low.
But the summer season needs a relatively thicker oil so as to reduce the thinning effect of the oil out of the engine.
Thus for Maine in the winter season, we need a low viscosity oil and for Florida a high viscosity oil in the summer season.
Therefore, option (c) is correct.
Answer:
Explanation:
From the given information:
Strain fracture toughness 
= 75 MPa
Tensile stress 
= 361 MPa
Value of Y = 1.03
Thus, the minimum length of the critical interior surface crack which will result to fracture can be determined by using the formula:
![a_c = \dfrac{1}{\pi} ( \dfrac{k_k}{\sigma Y})^2 \\ \\ a_c = \dfrac{1}{\pi} \Big [ \dfrac{75 \times \sqrt{10^3}}{361 \times 1.03 } \Big]^2 \\ \\ a_c = \dfrac{1}{\pi} \Big [ 6.378474693\Big]^2 \\ \\ \mathbf{ a_c = 12.95 \ mm}](https://tex.z-dn.net/?f=a_c%20%3D%20%5Cdfrac%7B1%7D%7B%5Cpi%7D%20%28%20%5Cdfrac%7Bk_k%7D%7B%5Csigma%20Y%7D%29%5E2%20%5C%5C%20%5C%5C%20%20a_c%20%3D%20%5Cdfrac%7B1%7D%7B%5Cpi%7D%20%5CBig%20%5B%20%5Cdfrac%7B75%20%5Ctimes%20%5Csqrt%7B10%5E3%7D%7D%7B361%20%5Ctimes%201.03%20%7D%20%5CBig%5D%5E2%20%5C%5C%20%5C%5C%20%20a_c%20%3D%20%5Cdfrac%7B1%7D%7B%5Cpi%7D%20%5CBig%20%5B%206.378474693%5CBig%5D%5E2%20%20%5C%5C%20%5C%5C%20%5Cmathbf%7B%20a_c%20%3D%2012.95%20%5C%20mm%7D)
