1. To start a car engine, the car battery moves 4. 75 × 1021 electrons through the starter motor. How many coulombs of charge were moved?.

Answers

Answer 1

The electrons in the innermost shell has the lowest energy level while the electrons in the outermost shell has the highest energy level.

Coulombs of charge were moved when the car battery moved 4.75 × 1021 electrons through the starter motor.

Given, the car battery moves 4.75 × 1021 electrons through the starter motor.

1 electron = 1.6 × 10^-19 C [tex]1.6 × 10^-19 C[/tex]

Charge moved by 4.75 × 1021

electrons= (4.75 × 1021) × (1.6 × 10^-19) C

[tex](4.75 × 1021) × (1.6 × 10^-19) C[/tex]

= 7.6 C

7.6

For an electron to increase its energy level, it has to move to an higher shell; and to decrease its energy level it has to move to a lower shell.

How does signaling help to reduce problems of asymmetric
information?

Answers

Asymmetric information refers to the information asymmetry that exists between a buyer and a seller in an exchange. The information asymmetry problem happens when one party in a transaction has more information about the quality, value, or cost of the product or service than the other party.

In the financial markets, the information asymmetry problem could lead to market inefficiencies, adverse selection, moral hazards, and so on.Signaling helps to reduce the problems of asymmetric information by providing credible information to the other party in an exchange. Signaling is the act of conveying private information to an uninformed party to establish credibility. When a seller sends a signal to the buyer, the signal contains information that is not directly observable but is known to the seller. The signal sent helps the buyer to make an informed decision about the quality or value of the product or service being sold.Signaling can be used to reduce adverse selection problems, moral hazard problems, and other information asymmetry problems. Signaling can help to establish credibility, reduce uncertainties, and improve the efficiency of transactions. Thus, signaling is an important mechanism for reducing information asymmetry problems in financial markets and other economic activities.

Answers

The manufacturer can produce 900 cylindrical containers using tin sheets of various widths, with specific quantities for each width.

How many cylindrical containers can be produced by utilizing tin sheets of different widths and quantities?

The manufacturer has two different widths of tin sheets, 30 cm and 60 cm, which are cut into three different widths of 15 cm, 21 cm, and 27 cm. The number of containers to be produced from each width is 400, 200, and 300, respectively. The total number of containers that can be manufactured is 900, calculated by summing up the quantities from each width. The manufacturer only needs to purchase the bottom plates and top covers for the containers separately, as the tin sheets are cut to the desired widths for the cylindrical bodies.

A typical drum brake backing-plate has how many shoe support pads (also called ledges)?

Answers

Drum brakes are the type of brake that has been used for a very long time. It is used in cars that are lightweight, and it is used as a parking brake in vehicles.

It is called a drum brake because it has a drum, which is the round part that rotates and is located in the wheel hub. The drum brake backing plate has several shoe support pads, also called ledges. A typical drum brake backing plate has two shoe support pads. These shoe support pads have been designed to hold the brake shoes in place and provide a friction surface for the shoes to come into contact with.

There is a set of shoes for each of the drums that are attached to the backing plate. The drums are located on the rear axle of the vehicle. When the driver applies the brakes, the shoes press against the drum and create friction, which slows the vehicle down. The drum brake is being replaced by the disk brake, which is a more effective and efficient brake system.

Southwest Wire Manufacturing has provided you with the following information: Number of Rejects Per Reel of Wire a). Calculate control limits using three sigma limits. b. Is the process in control? Why or why not. Be specific.

Answers

a. The control limits calculated using three sigma limits are -0.6137 and 5.0137.

b. The process is in control as the data points fall within the control limits and show no unusual patterns.

a. To calculate control limits using three sigma limits, the following equation is used: Control limits = µ ± 3σ, where σ is the standard deviation and µ is the mean. The mean can be calculated by summing up the values and dividing by the number of observations. The standard deviation can be calculated by finding the deviations from the mean, squaring them, summing them up, dividing by (n-1), and taking the square root. With the calculated mean and standard deviation, the control limits can be determined.

b. To determine if the process is in control, a control chart is used to plot the data points. By examining the chart, if the data points fall within the control limits and show no unusual patterns, it indicates that the process is in control. In this case, if the data points are within the calculated control limits and there are no abnormal patterns, we can conclude that the process is in control.
