Answer:
D.V.= - 1.34 %
Explanation:
Given that
V₁=50,000 L
T₁=25⁰C = 273 + 25 K =298 K
The final temperature ,T₂= 25 - 4 ⁰C = 21 ⁰C
T₂ = 21 + 273 K= 294 K
We know that for constant pressure process


V₂=49328.85 L
The percent decrease in the volume is given as

D.V.= - 1.34 %
Answer:
Therefore, height of instrument is 324.577 ft
Therefore, elevation of point x is 330 m
Explanation:
Given that
Plus sight on BM = 12.03 ft
Minus sight is = 5.43 ft
Elevation = 312.547 ft
Height of instrument is H.I
H.I = elevation on bench mark + plus sight
= 312.547 + 12.03 = 324.577 ft
Therefore, height of instrument is 324.577 ft
Elevation at point x is = H.I - minus sight
= 324.577 - (- 5.43)
= 330.00 m
Therefore, elevation of point x is 330 m
Answer:
For any material if ∈ is the axial strain then the lateral strain is given by -μ∈ is the lateral strain in the object
Where,
μ is the poisson's ratio of the material
The longitudinal strain is calculated as follows

Thus the lateral strain becomes

now by definition of lateral strain we have

By hookes law the stress developed due to the given strain is given by

Applying values we get

Thus the force is calculated as

Answer:
Employees who use hand and power tools and who are exposed to the hazards of falling, flying, abrasive and splashing objects, or exposed to harmful dusts, fumes, mists, vapors, or gases must be provided with the appropriate equipment needed, including Personal Protective Equipment, to protect them from the hazard.
Explanation:
