Whatever ur designing has to fit the requirements.
Answer:
58.44 g/mol The Molarity of this concentration is 0.154 molar
Explanation:
the molar mass of NaCl is 58.44 g/mol,
0.9 % is the same thing as 0.9g of NaCl , so this means that 100 ml's of physiological saline contains 0.9 g of NaCl. One liter of physiological saline must contain 9 g of NaCl. We can determine the molarity of a physiological saline solution by dividing 9 g by 58 g... since we have 9 g of NaCl in a liter of physiological saline, but we have 58 grams of NaCl in a mole of NaCl. When we divide 9 g by 58 g, we find that physiological saline contains 0.154 moles of NaCl per liter. That means that physiological saline (0.9% NaCl) has a molarity of 0.154 molar. We can either express this as 0.154 M or 154 millimolar (154 mM).
Answer:
False
Explanation:
When the horizontal shear forces act on the surface there is transverse shear stress at a particular point which is equal in magnitude. Pure bending is less common than a non uniform bending because the beam is not in equilibrium.
Answer:
Option C
Explanation:
The image given in the question represents an overflow tank
Since a water pump has rotor and blades (which is not visible in the given image), hence, this image is not of water pump.
The surge tank has a different structure as compared to that of overflow tank
Radiator looks like a metallic structure with parallel blades.
Hence, option C is correct
Answer:
efficiency of the engine is 0.4167
Explanation:
given data
T high = 1200 K
T low = 700 K
solution
we get here efficiency that is express as
efficiency =
.........................1
put here value of both temperature we get efficiency
efficiency = 1 -
efficiency = 1 - 0.58333
efficiency = 0.4167
so efficiency of the engine is 0.4167
