Answer:
A
Explanation:
An open circuit has infinite resistance, not 0. A circuit with continuity usually measures a few ohms or less, depending on the length and gauge of the wire and the condition of the connections. Often, on a general-purpose ohmmeter, the reading is very near 0 ohms.
Technician A is correct.

How long would a piece of wood need to be to make a diagonal brace for a rectangle that measures 4 inches by 3 inches? Use the Pythagorean theorem, a² + b² = c², to determine the answer. 5 inches 7 inches 12 inches 25 inches Select the correct answer.
Answer:
Length of a diagonal = 5 inches
Explanation:
Let [tex]a[/tex] and [tex]b[/tex] the sides of the rectangle and [tex]c[/tex] be the diagonal of the rectangle.
According to the Pythagorean theorem, sum of squares of base and perpendicular is equal to the square of hypotenuse.
As each angle of the rectangle is a right angle,
[tex]a^2+b^2=c^2[/tex]
Put [tex]a=4\,,\,b=3[/tex]
[tex]4^2+3^2=c^2\\16+9=c^2\\25=c^2\\\sqrt{25}=c\\ 5=c[/tex]
So,

Clarisse is an architect. What skills will she apply to integrate her visualized solutions with other aspects such as business and industry standards? Clarisse will apply BLANK skills to integrate her visualized solutions with other aspects such as business and industry standards.
Answer:
Conceptual problem-solving skills
Explanation:
Conceptual problem-solving is a way of solving problems by applying what we know to what we do not know. For Clarisse who is an architect, the knowledge she has about visualization, and the concepts of the business world are not quite related.
So to integrate her visualization solutions to business standards, she would have to compare the two spheres of knowledge to determine how to adapt one t the other.

An experimental arrangement for measuring the thermal conductivity of solid materials involves the use of two long rods that are equivalent in every respect, except that one is fabricated from a standard material of known thermal conductivity kA while the other is fabricated from the material whose thermal conductivity kB is desired. Both rods are attached at one end to a heat source of fixed temperature Tb, are exposed to a fluid of temperature [infinity] T[infinity], and are instrumented with thermocouples to measure the temperature at a fixed distance x1 from the heat source. If the standard material is aluminum, with kA= 200 W/m·K, and measurements reveal values of TA= 75°C and TB= 70°C at x1 for Tb= 100°C and [infinity] T[infinity]= 25°C, what is the thermal conductivity kB of the test material?
Answer: the thermal conductivity of the second material is 125.9 W/m.k
Explanation:
Given that;
The two rods could be approximated as a fins of infinite length.
TA = 75°C, θA = (TA - T∞) = 75 - 25 = 50°C
TB = 70°C θB = (TB - T∞) = 70 - 25 = 45°C
Tb = 100°C θb = (Tb - T∞) = (100 - 25) = 75°C
T∞ = 25°C
KA = 200 W/m · K , KB = ?
Now
The temperature distribution for the infinite fins are given by
θ/θb = e^(-mx)
θA/θb= e^-√(hp/A.kA) x 1 --------------1
θB/θb = e^-√(hp/A.kB) x 1---------------2
next we take the natural logof both sides,
ln(θA/θb) = -√(hp/A.kA) x 1 ------------3
In(θB/θb) = -√(hp/A.kB) x 1 ------------4
now we divide 3 by 4
[ ln(θA/θb) /in(θB/θb)] = √(KB/KA)
we substitute
[ In(50/75) /In(45/75)] = √(KB/200)
In(0.6666) / In(0.6) = √KB / √200
-0.4055/-0.5108 = √KB / √200
0.7938 = √KB / 14.14
√KB = 11.22
KB = 125.9 W/m.k
So the thermal conductivity of the second material is 125.9 W/m.k

Air is contained inside a vertical piston-cylinder assembly by a piston of mass 105 kg and face area of 0.05 m2 . The mass of air inside the cylinder is 20 grams, and the air initially occupies a volume of 50 liters. The atmosphere exerts a pressure of 101.3 kPa on the top of the piston. The volume of the air slowly decreases to 0.005 m3 , while maintaining constant pressure, as the specific internal energy of the air decreases by 175 kJ/kg. Neglecting friction between the piston and the cylinder wall, determine the heat between the surroundings and the air inside the piston-cylinder assembly in kJ
Answer:
ΔQ = 1.06 KJ
Explanation:
The amount of heat transfer between the piston-cylinder system and the surrounding can easily be found by using the First Law of Thermodynamics. The first law of thermodynamics can be written as follows:
ΔQ = ΔU + W
ΔQ = mΔu + PΔV
where,
ΔQ = Heat transfer between system and surrounding = ?
Δu = specific change in internal energy of the system = - 175 KJ/kg
m = mass of air = 20 g = 0.02 kg
P = Constant Pressure = 101.3 KPa
ΔV = Change in Volume = 0.05 m³ - 0.005 m³ = 0.045 m³
Therefore,
ΔQ = (0.02 kg)(-175 KJ/kg) + (101.3 KPa)(0.045 m³)
ΔQ = -3.5 KJ + 4.56 KJ
ΔQ = 1.06 KJ

a. An 80-percent efficient pump with a power input of 20 hp is pumping water from a lake to a nearby pool at ar ate of 1.5 ft3 /s through a constant-diameter pipe. The free surface of the pool is 80 ft above that of the lake. Determine the mechanical power used to overcome frictional effects in piping.
b. Water is pumped from a lake to a storage tank 15 m above at a rate of 70 L/s while consuming 15.4 kW of electric power. Disregarding any frictional losses in the pipes and any changes in kinetic energy. Determine:
1. The overall efficiency of the pump–motor unit.
b. The pressure difference between the inlet and the exit of the pump.
Answer:
A) mechanical power used to overcome frictional effects in piping = 2.373 HP
B) efficiency = 66.82%
Pressure difference = 147 KPa
Explanation:
We are given;
efficiency of pump; η = 80% = 0.8
power input of pump;P_pump,in = 20 hp
rate being pumped; Q = 1.5 ft³/s = 0.04248 m³/s
free surface of pool; Δz = 80 ft = 24.384 m
mechanical pumping power used to deliver water is;
W_u = η × P_pump,in
W_u = 0.8 × 20
W_u = 16 Hp
Now, change in total mechanical energy of water will be equal to the change in potential energy.
Thus, it is expressed as;
ΔE_mech = ρ × Q × g × Δz
Where ρ is density of water = 1000 kg/m³
Thus;
ΔE_mech = 1000 × 0.04248 × 9.81 × 24.384 = 10,161.5150592 J/s
Converting to HP gives;
ΔE_mech = 13.627 HP
Now, mechanical power used to overcome frictional effects is given by;
W_frict = W_u - ΔE_mech
W_frict = 16 - 13.627
W_frict = 2.373 HP
B) We are now given;
W_elect,in = 15.4 KW
Volumetric flow rate; q = 70 l/s = 0.07 m³/s
Height; h = 15 m
Mass flow rate; m' = qρ
Where ρ is density of water = 1000 kg/m³.
m' = 0.07 × 1000
m' = 70 kg/s
Now,
ΔE_mech = workdone through height of 15m
Thus;
ΔE_mech = m'gh
ΔE_mech = 70 × 9.8 × 15
ΔE_mech = 10,290 W = 10.29 Kw
efficiency of the pump–motor unit = ΔE_mech/(W_elect,in) = 10.29/15.4 = 0.6682 or 66.82%
Pressure difference = ρgh = 1000 × 9.8 × 15 = 147,000 Pa = 147 KPa

A rope is wrapped three and a half times around a cylinder. Determine the range of force T exerted on
the free end of the rope for maintaining equilibrium that is required to just support a 5 kN weight. The
coefficient of friction between the rope and the cylinder is 0.2
The range of force exerted at the end of the rope is; 285.7 N to 1,000 N.
What is the Net horizontal force?The net horizontal force of the cylinder when it is at equilibrium position can be found by applying Newton's second law of motion. Thus;
∑F = 0
F - μF_n = 0
We are given;
F_n = 5 kN = 5000 N
μ = 0.2
Thus;
F - 0.2(5,000) = 0
F - 1,000 = 0
F = 1,000 N
The strength of the applied force will be increasing as the number of turns of the rope increases. Thus;
Minimum force = Total force/number of turns of rope
Since rope is wrapped three and half times, then;
number of turns = 3.5
Thus;
minimum force = 1,000/3.5
minimum force = 285.7 N
Thus, the range of force exerted at the end of the rope is 285.7 N to 1,000 N.

From the top of a vertical cliff 80m high, the angles of depression of 2 buoys lying due west of the cliff are 23° and 15° respectively. How far are the buoys apart?
Answer:
110 m
Explanation:
The geometry of the problem can be modeled by a right triangle. The height of the cliff forms one leg, and the distance to a buoy forms the other leg. The angle of depression is opposite the height of the cliff. An appropriate trig relation is ...
Tan = Opposite/Adjacent
Solving for the Adjacent side (the distance to the buoy), we find ...
Adjacent = Opposite/Tan
distance to buoy 1 = (80 m)/tan(23°) ≈ 188.468 m
distance to buoy 2 = (80 m)/tan(15°) ≈ 298.564 m
Then the distance between the buoys is ...
298.564 -188.468 m ≈ 110 m
The buoys are about 110 meters apart.
