Answer:
Attached is the logic diagram.
Explanation:
Motion Sensors S1 S1 S3 S4
Master switch M
Siren Enable Switch A
Light Enable Switch L
Phone Call Enable Switch P
Buzzing Siren B
Flashing Light F
Call Box C
The logic operates as follows, when ANY of the sensors goes active (1), the output must be active, so for the sensors inputs we use an OR gate. After that the OR signal output goes to the switches AND gates, if any of the switches is off, the outputs are going to be LOW or (0)

Answer:
The Estimated uncertainty in a nominal displacement of 2 cm at the design stage is plus or minus 0.0124cm
Explanation:
uncertainty in a nominal displacement
= (u^2 + v^2)^(1/2)
assume from specifications that k = 5v/5cm
= 1v/cm
u^2 = (0.0025*2)^(2) + (0.005*10*2)^2 + (0.0025*2)^2
= 0.01225v
v = 2v * 0.001
= 0.002v
uncertainty in a nominal displacement
= (u^2 + v^2)^(1/2)
= ((0.01225)^2 + (0.002)^2)^(1/2)
= 0.0124 cm
Therefore, The Estimated uncertainty in a nominal displacement of 2 cm at the design stage is plus or minus 0.0124cm
The answer is T because a task is getting something done
Answer:
diameter is 14.83 mm
Explanation:
given data
height = 2 mm
to find out
internal diameter
solution
we consider here material is glass and liquid is water and angle is zero if no capillary rise
we apply here capillary rise formula that is
Capillary rise h = 2T / [ r×ρ×g ] ....................1
put here r is radius and ρ = 1000 kg/m³, T = 72.7 × N/m all value in equation 1
Capillary rise h = 2T / [ r×ρ×g ]
r = 2T / [ h×ρ×g ]
d/2 = 2T / [ h×ρ×g ]
d/2 = 2( 72.7 ×) / [ 2××1000×9.8 ]
d = 0.0148336 m
so diameter is 14.83 mm
