Answer:
50°
Explanation:
Complementary angles add up to 90°.
Supplementary angles add up to 180°.
Vertical angles are equal.
A + B = 90°
B = C
C = 180° − 140°
C = 40°
B = 40°
A = 50°
Answer with Explanation:
The capillary rise in 2 parallel plates immersed in a liquid is given by the formula
![h=\frac{2\sigma cos(\alpha )}{\rho gd}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B2%5Csigma%20cos%28%5Calpha%20%29%7D%7B%5Crho%20gd%7D)
where
is the surface tension of the liquid
is the contact angle of the liquid
is density of liquid
'g' is acceleratioj due to gravity
'd' is seperation between thje plates
Part a) When the liquid is water:
For water and glass we have
Applying the values we get
![h=\frac{2\times 7.28\times 10^{-2}cos(0)}{1000\times 9.81\times 2\times 10^{-3}}=7.39mm](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B2%5Ctimes%207.28%5Ctimes%2010%5E%7B-2%7Dcos%280%29%7D%7B1000%5Ctimes%209.81%5Ctimes%202%5Ctimes%2010%5E%7B-3%7D%7D%3D7.39mm)
Part b) When the liquid is mercury:
For mercury and glass we have
Applying the values we get
![h=\frac{2\times 485.5\times 10^{-3}cos(138)}{13.6\times 1000\times 9.81\times 2\times 10^{-3}}=-2.704mm](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B2%5Ctimes%20485.5%5Ctimes%2010%5E%7B-3%7Dcos%28138%29%7D%7B13.6%5Ctimes%201000%5Ctimes%209.81%5Ctimes%202%5Ctimes%2010%5E%7B-3%7D%7D%3D-2.704mm)
The negative sign indicates that there is depression in mercury in the tube.
Answer:
Option (d) MEP and IHP
Explanation:
MEP stands for Mean Effective Pressure and IHP stands for Indicated Horse Power
In engines (Internal Combustion), engine indicator is generally to indicate the indicate the changes in pressure inside the cylinder of an Internal Combustion Engine or IC engines. Once, Mean Effective Pressure of the engine is calculated it further helps to calculate the Horse power and both these quantities, i.e., MEP and IHP are displayed on the engine indicator.
Throughout the Word of God, water is a symbol, a "type," of the spirit of God, and is ... to represent holy spirit, that is, the divine nature and power of God. ... The average person can go about 60 days without food before he ... record illustrating the analogous relationship between water and the holy spirit.
