The given statement " we can copy only the columns we want to into another, existing table" is true because we can select specific columns from one table and copy them to another existing table using the INSERT INTO statement in SQL.
The INSERT INTO statement in SQL allows us to copy specific columns from one table to another existing table. By specifying the desired columns in the SELECT statement, we can retrieve only the necessary data and insert it into the target table. This is particularly useful when we don't want to copy the entire source table but only a subset of columns. The statement can also be customized with additional clauses, such as WHERE or ORDER BY, to further filter or sort the data being copied.

Refrigerant-134a at 1 MPa and 100 C is to be cooled to 1 MPa and 28 C in a condenser by air. The air enters at 125 kPa and 25 C with a mass flow rate of 697 kg/min and leaves at 97 kPa and 58 C. Determine the mass flow rate of the refrigerant. Assume air has a constant heat capacity determined at room temperature. Report the mass flow rate of the refrigerant in kg/min with one decimal digit, for example 95.3 or 105.6.
Tech A says that radial ply tires have much more flexible sidewalls than bias-ply tires because of their construction. Tech B says that bias-ply tires have a more durable construction than radial tires. Who is correct?
Answer:
Tech A and Tech B are correct
Explanation:
Tech A is correct because radial ply tires have more flexible sidewalls than radial tires due to the fact that radial tires make use of two or more layers of casing piles and are thus not much flexible.
Also, tech B is correct because bias-ply tires typically have more durable construction than radial tires
"An electric power distributor charges residential customers $0.08 per kilowatt-hour (kWh). The company advertises that ""green power"" is available in 145 kWh blocks for an additional $3.50 per month. (green power is generated from solar, wind power and methane sources.) If a certain customer uses an average of 400 kWh per month and commits to one monthly 150 kWh block of green power, what is her annual power bills?
What is the average cost per kWh with green power during the year? why does green power cost more than conventional power?
The annual power bill for this customer would be $1,076. This includes the cost of 400 kWh per month at $0.08 per kWh, plus 12 monthly blocks of 145 kWh green power at an additional cost of $3.50 per month.
The average cost per kWh with green power during the year would be $0.087 per kWh. This is calculated by the sum of monthly cost of 400 kWh at $0.08 per kWh, plus the 12 monthly blocks of 145 kWh green power at an additional cost of $3.50 per month, and dividing by the total number of kilowatt-hours used during the year (400 + 145 = 545).
There are a few factors that could make green energy more expensive than traditional energy. First, compared to conventional power, the infrastructure for producing and delivering green energy is frequently more expensive. Second, suppliers can charge more since there is frequently a greater demand for green energy than for conventional energy.
Green power is defined as electricity generated from renewable energy sources similar as solar, wind, geothermal, biogas, eligible biomass, and low- impact small hydroelectric sources.
Therefore, green power may be more expensive than conventional power due to government incentives or regulations.

Briefly explain thermal expansion using the potential energy–versus–interatomic spacing curve.
As the temperature of the material increases, the potential energy of the molecules increases. Thermal expansion occurs due to changes in temperature, and interatomic distances increase as potential energy increases.
What are the uses of Thermal Expansion?Thermal expansion is used in a variety of applications such as rail buckling, engine coolant, mercury thermometers, joint expansion, and others.
It is to be noted that an application of the concept of liquid expansion in everyday life concerns liquid thermometers. As the heat rises, the mercury or alcohol in the thermometer tube moves in only one direction. As the heat decreases, the liquid moves back smoothly.

HW: 2-3-9 The rigid beam AB is supported by a pin at C and the two springs. The spring at A has a spring constant (k) of 2000lb/in and the spring at B has a spring constant of 3000lb/in. Find the force in each spring and the displacement of point D. Recall: Fspring= K∆
Force in spring at A = 12000lb and force in spring at B = 18000lb, displacement of point D = 6 inches.
To solve for the force in each spring and the displacement of point D, we need to use the principle of equilibrium and the equation for Hooke's Law, which states that the force in a spring is equal to the spring constant multiplied by the displacement.
Since the beam is in equilibrium, the sum of the forces in the x-direction must be zero, and the sum of the forces in the y-direction must be zero.
We can use this to solve for the force in spring A and spring B in terms of displacement of point D.
Fx=F_A -F_B =0
Fy=F_A+F_B-mg=0
Where F_A and F_B are the force in spring A and B respectively, and mg is the weight of the beam acting at the center of mass.
Solving for these equations we can find out that F_A =12000lb and F_B=18000lb and displacement of point D=6 inches.

A sensor produces a signal with amplitude 15 mV. A voltage amplifier must amplify the signal such that the amplitude of the output signal is at least 2 V. What is the minimum voltage gain (in dB) for the amplifier to meet the requirements
Answer:
42.50 dB
Explanation:
Determine the minimum voltage gain
amplitude of input signal ( Vi ) = 15 mV
amplitude of output signal ( Vo) = 2 V
Vo = 2 v
therefore ; minimum gain = Vo / Vi = 2 / ( 15 * 10^-3 )
= 133.33
Minimum gain in DB = 20 log ( 133.33 )
= 42.498 ≈ 42.50 dB
When laying supply hose to the fire scene during a roadway response, lay the hose: (138)

B. When laying supply hose to the fire scene during a roadway response, lay the hose so that it is not on the street.
When laying supply hose to the fire scene during a roadway response, it is important to lay the hose in a way that it is not on the street. This is crucial for several reasons. Firstly, having the hose on the street can obstruct traffic and impede the movement of emergency vehicles. Secondly, it can pose a safety hazard for both firefighters and motorists, increasing the risk of accidents or injuries. Instead, the hose should be laid alongside the street or in a designated area away from the main roadway. This allows for unobstructed traffic flow and ensures the safety of responders and the public. Firefighters should follow proper procedures and guidelines to ensure the effective and safe deployment of supply hose during roadway responses.

The wing of the Fairchild Republic A-10A twin-jet close-support airplane is approximately rectangular with a wingspan (the length perpendicular to the fl ow direction) of 17.5 m and a chord (the length parallel to the fl ow direction) of 3 m. The airplane is fl ying at standard sea level with a velocity of 200 m/s. If the fl ow is considered to be completely laminar, calculate the boundary layer thickness at the trailing edge and the total skin friction drag. Assume that the wing is approximated by a fl at plate. Assume incompressible fl ow.
An airplane flying across the sky experience drag force determined by the factors including the speed of flight, coefficient of skin friction and the reference surface area
The boundary layer thickness is approximately 0.233 cm
The total skin friction drag, is approximately 265 N
Reason:
First part:
Given parameters are;
Chord length, L = 3 m
Velocity of the plane, V = 200 m/s
Density of the air, ρ = 1.225 kg/m³
Viscosity of the air, μ = 1.81 × 10⁻⁵ kg/(m·s)
The Reynolds number is given as follows;
\(R_{eL} = \dfrac{\rho \times V \times L}{\mu}\)
Therefore;
\(R_{eL} = \dfrac{1.255 \times 200 \times 3}{1.81 \times 10^{-5}} = 4.16022099448 \times 10^7 \approx 4.16 \times 10^7\)
Boundary layer thickness, \(\delta_L\), for laminar flow, is given as follows;
\(\dfrac{ \delta_L }{L}=\dfrac{5.0}{\sqrt{R_{eL} } }\)
\({ \delta_L }=\dfrac{5.0 \times L}{\sqrt{R_{eL} } }\)
Which gives;
\({ \delta_L }=\dfrac{5.0 \times 3}{\sqrt{4.16 \times 10^{7}} } \approx 2.33 \times 10^{-3 }\)
The boundary layer thickness, \(\delta_L\) ≈ 2.33 × 10⁻³ m = 0.233 cm
Second Part
The total skin friction is given as follows;
\(Dynamic \ pressure, q = \dfrac{1}{2} \cdot \rho \cdot V^2\)
Therefore;
\(q = \dfrac{1}{2} \times 1.225 \times 200^2 = 24,500\)
The dynamic pressure, q = 24,500 N/m²
Skin friction drag coefficient, \(C_D\), is given as follows;
\(C_D = \dfrac{1.328}{\sqrt{R_{eL} } }\)
Therefore;
\(C_D = \dfrac{1.328}{\sqrt{4.16 \times 10^7 } } \approx 2.06 \times 10^{-4}\)
Skin friction drag, \(D_f\), is given as follows;
\(D_f\) = q × \(C_D\) × A
Where;
A = The reference area
∴ \(D_f\) = 24,500 N/m² × 2.06 × 10⁻⁴ × 3 m × 17.5 m = 264.9675 N ≈ 265 N
The total skin friction drag, \(D_f\) ≈ 265 N
