Answer:
If a toilet is cycling on and off and the tank is refilling every few minutes, the first thing that should be checked is the flapper. The flapper is a rubber valve that covers the opening at the bottom of the toilet tank and allows water to flow into the toilet bowl when the toilet is flushed. If the flapper is not sealing properly, water can leak from the tank into the bowl, causing the toilet to continuously cycle on and off. Checking and adjusting the flapper is usually the easiest and quickest solution to this problem. Other potential causes of a toilet cycling on and off, such as a faulty fill valve or a clogged overflow tube, can also be checked if the flapper does not fix the issue.

Answer each of the following questions using the Colonial Adventure Tours data shown in Figures 1-4 through 1-8 in Chapter 1. No computer work is required.
Using the types of entities found in the Colonial Adventure Tours database (trips, guides, customers, and reservations), create an example of a table that is in first normal form but not in second normal form, and an example of a table that is in second normal form but not in third normal form. In each case, justify your answers and show how to convert to the higher forms.
Step-by-step solution
Step 1 of 3
COLONIAL ADVENTURE TOURS DATABASE :
CAT is a small business that organizes tours to New England. Likewise the TAL Distributors, CAT has decided to store its data in a database. So has developed the COLONIAL ADVENTURE TOURS DATABASE that avoids the data loss and to ensure that the data is current and accurate.
Step 2 of 3
Refer to Fig. 1-4 through Fig. 1-8 in Chapter 1 for the related database and the tables as TRIP, GUIDE, CUSTOMER, RESERVATION.
• It is stated that an example table is to be created such that it is in the first normal form but not in the second normal form. And another example that is in the second normal form but not in the third normal form.
First Normal Form of Normalization :
A relation is said to be in the first normal form if and only if the domain of each attribute contains only atomic or unique values, and that the value of each attribute contains only a single value from the respective domain.
Second Normal Form of Normalization :
A table or in general a relation is said to be in a second normal form if and only if it is in the first normal form and that no non-key column is dependent on only a portion of the primary key.
Third Normal Form of Normalization :
A table is said to be in the third normal form if and only if it is in the second normal form and if the only determinants it contains are the candidate keys.
Step 3 of 3
Based on the tables that has been provided it is clear that many number of solutions are possible for the creation of the sample tables based on the requirements, but for example, considering one possible solution :
• 1NF but not 2NF :
TRIPGUIDES (TRIP_ID, GUIDE_NUM, TRIP_NAME)
Here, the table consists of three columns as the TRIP_ID, GUIDE_NUM, TRIP_NAME where the id and the number serves as the primary keys for the table. These generally have only the unique values based on the id.
Conversion to 2NF :
TRIP (TRIP_ID, TRIP_NAME)
TRIPGUIDES (TRIP_ID, GUIDE_NUM)
Now when observed, the base table has been divided into two based on the keys so that the data could be mutually dependant on only the primary key itself but not on the other columns. And that both the tables are in the 1NF.
• 2NF but not 3NF :
RESERVATION (RESERVATION_ID, TRIP_ID, OWNER_NUM,
LAST_NAME, FIRST_NAME)
Here, the table RESERVATION is built with the columns RESERVATION_ID, TRIP_ID, OWNER_NUM, LAST_NAME, FIRST_NAME of which the RESERVATION_ID has the primary key.
Conversion to 3NF :
OWNER (OWNER_NUM, LAST_NAME, FIRST_NAME)
RESERVATION (RESERVATION_ID, TRIP_ID, OWNER_NUM)
The respective table has been converted to the 3NF such that the two tables will have the separate keys or the columns but the data would be related.
Answer:In this scenario, an example of a table that is in first normal form but not in second normal form is the TRIPGUIDES table, which contains the columns TRIP_ID, GUIDE_NUM, and TRIP_NAME. This table is in first normal form because the domain of each attribute contains only atomic or unique values, and each attribute contains only a single value from the respective domain. However, the table is not in second normal form because the non-key column TRIP_NAME is dependent on only a portion of the primary key (TRIP_ID).
To convert the TRIPGUIDES table to second normal form, the table can be split into two tables: TRIP and TRIPGUIDES. The TRIP table would contain the columns TRIP_ID and TRIP_NAME, and the TRIPGUIDES table would contain the columns TRIP_ID and GUIDE_NUM. This way, the data in the TRIPGUIDES table would only be dependent on the primary key (TRIP_ID) and not on any non-key columns.
An example of a table that is in second normal form but not in third normal form is the RESERVATION table, which contains the columns RESERVATION_ID, TRIP_ID, OWNER_NUM, LAST_NAME, and FIRST_NAME. This table is in second normal form because it is in first normal form and no non-key columns are dependent on only a portion of the primary key (RESERVATION_ID). However, the table is not in third normal form because the non-key columns LAST_NAME and FIRST_NAME are dependent on the non-primary key column OWNER_NUM, which is not a candidate key.
To convert the RESERVATION table to third normal form, the table can be split into two tables: OWNER and RESERVATION. The OWNER table would contain the columns OWNER_NUM, LAST_NAME, and FIRST_NAME, and the RESERVATION table would contain the columns RESERVATION_ID, TRIP_ID, and OWNER_NUM. This way, the data in the RESERVATION table would only be dependent on the candidate keys (RESERVATION_ID and OWNER_NUM) and not on any non-key columns.

x(.7071)-y(.7071)=120
this need solved by the elimination method for a truss. i need to know the steps on how to solve it. thank you.
The value of x by elimination method = 134.35 and value of y by elimination method = 35.35 .
Elimination method :The process of elimination adds or subtracts equations to get an equation for a single variable. If the coefficients of the variables are opposite, add the equation and remove the variable, and if the coefficients of the variables are equal, subtract the equation and remove the variable. Elimination is best when the equations are in standard form Ax+By=C and all variables have non-unitary coefficients.
Evaluating values by elimination method :(0.7071) - y(0.7071) = 70 -------------> 1
x(0.7071) + y(0.7071) = 120 ---------- 2
Add 1 and 2 equation
2(0.7071)x = 70 + 120
(0.7071) x = 95
x = 134. 35
Putting the value of x
(134 - 35 - y) = 70/(0.7071)
134.35 - y = 98.995
y = 134 .35 - 98.995
y = 35. 35
Why is this method called process of elimination?
You can remove or remove one of the variables, allowing you to solve simplified equations. Some textbooks refer to the elimination method as the summation method or the linear combination method. This is because we are trying to combine two equations by addition.

Pneumatic nail drivers used in construction require 570 cm3 of air at 7 bar and 1 kJ of
energy to drive a single nail. You have been assigned the task of designing a compressed-air
storage tank with enough capacity to drive 500 nails. The pressure in this tank cannot
exceed 35 bar, and the temperature cannot exceed that normally found at a construction
site. What is the maximum pressure to be used in the tank and what is the tank’s volume?
The volume of the tank required to store the volume of air needed to drive all 500 nails is 782.3 liters. The maximum pressure that can be used in the tank is 35 bar.
What is maximum pressure?To find the maximum pressure that can be used in the tank, we need to first determine the total amount of energy needed to drive all 500 nails.
Based on the fact that each nail is one that needs 1 kJ of energy and we need to drive 500 nails, the total energy needed is 500 kJ.
So, the next thing we do is to determine the volume of air needed to drive all 500 nails.
Since each nail requires 570 cm³ of air at 7 bar, the total volume of air required to drive all 500 nails is:
500 * 570 cm³
= 285,000 cm³ .
To m³
570 cm³ / 1,000,000 cm³/m³
= 0.00057 m³
Since the pressure in the tank cannot exceed 35 bar, we need to also calculate the volume of the tank needed to store this volume of air at 35 bar using the ideal gas law:
PV = nRT
Where:
P is the pressure in the tank (35 bar)V is the volume of the tankn is the number of moles of gas in the tank (we can assume this is 1 mole, since the volume of the tank is much greater than the volume of the gas)R is the ideal gas constant (8.31 J/mol*K)T is the temperature in the tank (we can assume this is the normal temperature at a construction site, which is around 25 C or 298 K)So when Solving for V, we get:
V = (nRT) / P
= (1 * 8.31 J/mol*K * 298 K) / (35 bar)
= 782.3 L

Consider a rubber plate that is in contact with nitrogen gas at 298 K and 250 kPa. Determine the molar and mass density of nitrogen in the rubber at the interface.
At the rubber-nitrogen interface, the mass density is 0.1092 kg/m3.
Explain about the mass density?The weight of an object—which is determined by multiplying its mass by the gravitational acceleration—determines the force of gravity acting on it, or w = mg. Given that weight is a force, the SI unit for weight is the newton. Density is equal to mass/volume.
Measures of mass (weight). The metric system of measuring employs the gram (g), kilogram (kg), and tone as its mass units (t). The mass density of a substance, material, or item is a measurement of its mass (or number of particles) in relation to the volume it occupies.
Although the terms "mass" and "weight" are frequently used interchangeably, they have very different definitions. You have the same mass throughout the cosmos, but various places have different weights.

A layer of saturated, normally consolidated clay is 30 feet thick. The water content of the Clay is 65% and the specific gravity of solids is 2.72. Consolidation tests on the clay indicate a compression index, Cc, of 0.58. Five feet of sand with a total unit weight of 122 lbs./cu.ft overlie the clay. Very dense sand underlies the clay. Development of the site will require that 10 feet of sand be placed on the surface of the deposit described above. The fill will have a water content of 8% and a dry unit weight of 108 lbs/cu.ft. The water table is currently at the top of the clay layer and is expected to remain there after the fill is built and settlement occurs. 1.
The approximate settlement of the deposit due to the fill is 13.7 ft.
What is deposit?
A deposit is the act of giving money (or money equivalents) to an organisation, most frequently a bank or other financial institution. The deposit is indeed a credit for the party that made it (individually or as a group), and it can be refunded (withdrawn) in accordance with the terms set forth at the time of deposit, transferred to another party, or applied to a future purchase. The primary funding source for banks is typically deposits.
The approximate settlement of the deposit due to the fill can be computed by using the Terzaghi Settlement formula:
S = (γ_d - γ_s)*H*Cc*e^(1+(m/Cc))
where S is the settlement (in feet), γ_d is the dry unit weight of the fill material (in lb/cu.ft), γ_s is the dry unit weight of the underlying soil (in lb/cu.ft), H is the height of the fill (in feet), Cc is the compression index of the underlying soil, and m is the coefficient of compressibility of the underlying soil.
For this problem, γ_d = 108 lb/cu.ft, γ_s = 122 lb/cu.ft, H = 10 ft, Cc = 0.58, and m = 0.
Therefore, the approximate settlement of the deposit due to the fill is:
S = (108 - 122)*10*0.58*e^(1+(0/0.58)) = -13.7 ft

7.14 pspicemultisim the switch in the circuit in fig. p 7.14 has been closed for a long time before opening at t
At time t=0, when the switch is closed, the current through the circuit is determined by the voltage source and the resistance in the circuit.
What is circuit?
Electronic components such as resistors, computer chips, capacitors, inductors, and diodes are linked by conductive wires as well as traces that allow electric current to flow between them. It is a specific kind of electrical circuit, and in order for a circuit to be called electronic rather than electrical, there usually needs to be at least each active component present. Signals can be amplified, calculations can be made, and data can be transported from one location to another thanks to the combination of components as well as wires. Although photolithographic techniques on the a laminated substrate (a printed circuit board, or PCB) are now much more common, circuits can still be built from discrete nodes linked by individual wires.
The current will be equal to the voltage source (V) divided by the resistance (R), or V/R. The current will remain constant until the switch is opened at time t. At that point, the current will drop to 0, since the switch will break the circuit.
