Answer:
1.4 mL
Explanation:
Given that:
volume of alcohol [tex]V_0[/tex] = 500
Temperature change ΔT = (30° - 5°)C
=25° C
[tex]\beta_{ alcohol }= 1.12 \times 10^{-4} / ^0C[/tex]
The increase in volume ΔV = [tex]\alpha \times V_o \times \Delta T[/tex]
[tex]= 500 \times 1.12 \times 10^{-4} / ^0 C\times 25^0 C[/tex]
= 1.4 mL
What are motion study principles? How are they classified?
Frederick Taylor created a series of guidelines known as the "motion study principles" to boost productivity at work. Time study, motion study, fatigue study, etc technique conduct research are the four divisions into which they fall.
What is motion study principles?Motion studies are the study of actions like lifting, putting things down, standing, changing direction, and other actions that are made when performing routine work.
In order to execute the task effectively in less time, unnecessary moves are attempted to be removed. The following three headings comprise the fundamentals: Making use of the human body. The layout of the workplace. Machinery and tools design.

When block C is in position xC = 0.8 m, its speed is 1.5 m/s to the right. Find the velocity of block A at this instant. Note that the rope runs around the pulley B and a pin attached to block C, as indicated.
Answer:
The answer is "2 m/s".
Explanation:
The triangle from of the right angle:
[tex]\to (x_c-0.8)+(1.5+y_4) +\sqrt{x_c^2 + 1.5^2}= constant[/tex]
Differentiating the above equation:
[tex]\to V_c +V_A+ \frac{X_cV_c}{\sqrt{x_c^2 +1}}=0\\\\\to 1-V_A+ \frac{0.8 \times 1.5}{\sqrt{ 0.8^2+1.5}}=0\\\\[/tex]
[tex]\to V_A= \frac{1.2}{\sqrt{ 0.64+1.5}}+1\\\\[/tex]
[tex]= \frac{1.2}{ 1.46}+1\\\\= \frac{1.2+ 1.46}{ 1.46}\\\\ = \frac{2.66}{1.46}\\\\= 1.82 \ \frac{m}{s}\\\\= 2 \ \frac{m}{s}[/tex]

53. The plan of a building is in the form of a rectangle with
centerline dimension of outer walls as 9.7mx14.7m. The
thickness of the wall in super structure is 0.30m. Then its
plinth area is
a) 150m
b) 145m2
c) 145.5m
d) 135.36m
.
Answer: 150m
Explanation:
The following can be depicted from the question:
Dimensions of outer walls = 9.7m × 14.7m.
Thickness of the wall = 0.30 m
Therefore, the plinth area of the building will be:
= (9.7 + 0.30/2 + 0.30/2) × (14.7 × 0.30/2 + 0.30/2)
= 10 × 15
= 150m
The plinth area will be 150m.
Given information
Dimensions of outer walls = 9.7m × 14.7m.
Thickness of the wall = 0.30 m
Plinth area of the building = (9.7 + 0.30/2 + 0.30/2) × (14.7 × 0.30/2 + 0.30/2)
Plinth area of the building = 10 × 15
Plinth area of the building = 150m
Therefore, the Option A is correct.
