3. The joint between the base of a toilet and the closet flange is sealed with
O A. a molded plastic gasket.
OB. a rubber or wax-ring seal.
O C. plumber's putty.
D. adhesive caulk.

Answers

The joint between the base of a toilet and the closet flange is sealed with a rubber or wax-ring seal. This is plumbing.

Why is this so?

A rubber or wax-ring seal is commonly used to seal the junction between the base of a toilet and the closet flange. A toilet wax ring is another name for this sort of seal.

The wax ring is wrapped around the aperture of the closet flange before the toilet is dropped into it, forming a seal between the toilet's base and the flange.

The wax ring is intended to compress and form a watertight barrier, preventing water and smells from escaping from the toilet's base. Other sealing techniques, such as plumber's putty or adhesive caulk, are not normally suggested since they may not offer a stable and long-lasting seal.

An electric heater has a power of 1100W. At a rate of 8¢ per kWh, how much does it cost to use the heater 3 hours a day for 30 days?

Answers

It will cost $7.92 to use the electric heater for 3 hours a day for 30 days at a rate of 8¢ per kWh.

To calculate the cost of using the electric heater for 3 hours a day for 30 days, we need to determine the energy consumption in kWh first.

The power of the electric heater is given as 1100W, which means it consumes 1.1 kWh of energy per hour (since 1 kWh = 1000W). Therefore, the energy consumption in 3 hours is 3.3 kWh (1.1 kWh x 3 hours).

Now, we can calculate the total energy consumption for 30 days, which is 99 kWh (3.3 kWh x 30 days).
Using the given rate of 8¢ per kWh, we can calculate the total cost of using the electric heater for 30 days as follows:

Total Cost = Energy Consumption x Rate per kWh

Total Cost = 99 kWh x 8¢

Total Cost = $7.92

C. The outside forms are set up first.
D. The high point becomes the grade for the footing.

Answers

The correct statement of the process for forming a footing is C. The outside forms are set up first.

What is footing in Building?

The footing is the lowest component of a foundation. Footings are important in construction because they distribute the weight of the structure uniformly throughout the whole structure, preventing it from sinking into the ground.

The foundation is the structure that carries weights from the superstructure to the ground, whereas the footing is the foundation that is in touch with the earth.

A foundation can be shallow or deep, and a footing is a shallow foundation. As a result, all footings are foundations, but not all foundations are footings.

A waterproof joint is typically made between a sink or lavatory faucet and the fixture using plumber's putty, a rubber or wax-ring seal, construction adhesive, or latex caulk

What is a Waterproof joint?

Usually, a watertight connection is established between a sink or bathroom faucet and the fixture by utilizing various materials such as plumber's putty, rubber or wax-ring seal, construction adhesive, or latex caulk.

A popular substance used to form a water-resistant seal at the bottom of a faucet is known as a plumber's putty.

A common method of preventing leaks between the floor flange and the toilet base in toilet installations is by utilizing either a rubber or wax-ring seal.

An enduring adhesive, such as construction adhesive, can establish a robust adhesion between the fixture and the faucet, ensuring a more lasting installation.

Finally, latex caulking is a viable solution for sealing gaps and inhibiting water from seeping into the periphery of the faucet.

The final position of a car can be predicted with the following equation: Position = -2.5 (time) + 25 Where is the car’s position at 3.0 seconds? When would the car reach position 0.0 meters?

Answers

Answer:

The car's position at 3.0 seconds is 17.5 meters. The car will reach 0.0 meters at 10 seconds.

Explanation:

You can rewrite the equation as P= -2.5t+25. t=time and P is equal to position; so you will plug in 3.0 seconds into t. The equation will now look like: P = -2.5(3.0)+25

P = -2.5(3.0) + 25

P = -7.5 + 25

P = 17.5 meters

Now, to find when the car reaches 0.0 meters, we will plug that into P since P = position and will solve for t.

P = -2.5t + 25

0.0 = -2.5t + 25

-25                 -25

-25 = -2.5t

-25/-2.5 = -2.5t/-2.5

10 = t

So the car will reach 0.0 meters at 10 seconds.

4. Tony Hawk weighs about 60 kg. Calculate the difference in the pressure placed on the snow if he was standing in the snow on one snowshoe compared to standing in the snow in one boot. The area of the snowshoe is 0.20 m² and the area of the boot is 0.05 m².​

Answers

The difference in pressure placed on the snow when Tony Hawk stands on one snowshoe compared to standing in one boot is 800 Pa.

1. Convert the weight of Tony Hawk from kg to N (Newton):

  Weight = Mass x Gravity

  Given that Tony Hawk weighs about 60 kg and the acceleration due to gravity is approximately 9.8 m/s²,

  Weight = 60 kg x 9.8 m/s² = 588 N

2. Calculate the pressure exerted by Tony Hawk on the snow when standing on one snowshoe:

  Pressure = Force / Area

  Given that the area of the snowshoe is 0.20 m²,

  Pressure on snowshoe = 588 N / 0.20 m² = 2940 Pa

3. Calculate the pressure exerted by Tony Hawk on the snow when standing in one boot:

  Given that the area of the boot is 0.05 m²,

  Pressure on boot = 588 N / 0.05 m² = 11760 Pa

4. Calculate the difference in pressure placed on the snow:

  Difference in pressure = Pressure on snowshoe - Pressure on boot

  Difference in pressure = 2940 Pa - 11760 Pa = -8820 Pa

Note: The negative sign indicates that the pressure on the snowshoe is lower compared to the pressure on the boot. However, in this context, the absolute value of the difference (8820 Pa) represents the magnitude of the pressure difference.

Can someone teach me how to find all valid minterms of any given truth table?

Answers

Explanation:

A minterm is a product of variables, in which each variable appears exactly once, either complemented or not. When a truth table is represented in a sum of products form, there is one minterm for each line in the table for which the output is True (1).

Suppose I have a truth table as follows, with inputs A, B and output Z.

  AB Z

  00 1

  01 0

  10 1

  11 0

When I write the minterms, I use a complemented variable where the input is 0, and an uncomplemented variable where the input is 1. The minterm is expressed as a product of those variables.

Here, there are 2 lines in the table with outputs Z=1. The input conditions AB for those outputs are 00 and 10, so the corresponding minterms are A'B' and AB', where the apostrophe indicates the variable is complemented.

This table is then represented by the sum of products ...

  Z = A'B' + AB'

You have all of the valid minterms when you have one for each line of the table where the output is 1.

__

Comment on truth table representation

Truth tables can be represented a number of ways. A nice representation for the purpose of identifying minterms is a list of the output for every possible combination of inputs. We have used that form above.

Sometimes, you may see minterms listed as decimal numbers in the range of 0 to 2^n -1 when there are n input variables. Then, the minterms are developed from the binary equivalents of those decimal numbers.

Example:

Logic with 4 input variables has minterms 7, 8, and 15. The binary equivalents of these numbers are 0111, 1000, 1111. The corresponding minterms (for inputs a, b, c, d) are a'bcd + ab'c'd' + abcd = z. Three numbers are listed, so we know we have all of the valid minterms when we have three corresponding minterms.

__

Additional comment

In some cases, outputs will be listed as "don't care." Another set of minterms can be generated for the don't cares. These can be used in the logic minimization process.

An asynchronous counter wired to count from 6 to 2 requires a reset value of 7 (binary: 111). The count limit logic looks for the binary value 111 to reset the circuit. In decimal form, the reset value is 7.

It seems that you have described an asynchronous counter that counts from 6 to 2 and requires a reset value of 7. In binary form, the reset value is represented as 111, which corresponds to the decimal value 7.

An asynchronous counter is a sequential circuit that sequentially goes through a defined sequence of states. Each state corresponds to a unique binary value. In this case, the counter starts at 6 (binary: 110) and counts down to 2 (binary: 010). When the counter reaches the value of 2, it should be reset back to 7 to restart the counting sequence.

To implement the reset functionality, a count limit logic is used. This logic detects when the counter reaches the binary value 111, which represents the decimal value 7. When this condition is met, the counter is reset to its initial state of 6, and the counting sequence starts over again.

Please note that the implementation details of the counter and the count limit logic may vary depending on the specific design and circuitry used.
