The primary winding of a 120 volt transformer has 200 turns. The secondary winding has 20 turns. What is the secondary winding voltage
Answer:
12 volts
Explanation:
The voltage ratio is equal to the turns ratio.
secondary/primary = 20/200 = v2/120
v2 = 120(20/200) = 12
The secondary winding voltage is 12 volts.

Explanation:
First drilled to a depth of 1 47/64 how much deeper must it be drilled to reach the depth indicated?
Answer:
1 13/64
Explanation:
The depth of the hole is the height of the block less the remaining material below the hole:
depth = 1 3/8 +1 15/16 - 3/8 = (1 3/8 -3/8) +1 15/16 = 2 15/16
We want to find the difference between this depth and the depth of the hole already drilled:
2 15/16 -1 47/64 = 2 60/64 -1 47/64
= (2 -1) +(60 -47)/64 = 1 13/64
The hole must be drilled 1 13/64 deeper to match the drawing.
The Environmental Protection Agency (EPA) has standards and regulations that says that the lead level in soil cannot exceed the limit of 400 parts per million (ppm) in public play areas designed for children. Mike is an inspector, and he takes 50 randomly selected soil samples from a site where they are considering building a playground.
These data show a sample mean of x = 390.25 ppm and standard deviation of Sx = 30.5 ppm. Answer the following:
1. Determine the critical t value and along with the confidence interval for 95% level of
confidence. 2. What does this interval suggest?
Answer:
See below
Explanation:
Check One-Sample T-Interval Conditions
Random Sample? √
Sample Size ≥30? √
Independent? √
Population Standard Deviation Unknown? √
One-Sample T-Interval Information
Formula --> [tex]CI=\bar{x}\pm t^*(\frac{S_x}{\sqrt{n}})[/tex]Sample Mean --> [tex]\bar{x}=390.25[/tex]Critical Value --> [tex]t^*=2.0096[/tex] (given [tex]df=n-1=50-1=49[/tex] degrees of freedom at a 95% confidence level)Sample Size --> [tex]n=50[/tex]Sample Standard Deviation --> [tex]S_x=30.5[/tex]Problem 1
The critical t-value, as mentioned previously, would be [tex]t^*=2.0096[/tex], making the 95% confidence interval equal to [tex]CI=\bar{x}\pm t^*(\frac{S_x}{\sqrt{n}})=390.25\pm2.0096(\frac{30.5}{\sqrt{50}})\approx\{381.5819,398.9181\}[/tex]
This interval suggests that we are 95% confident that the true mean levels of lead in soil are between 381.5819 and 398.9181 parts per million (ppm), which satisfies the EPA's regulated maximum of 400 ppm.
When the pressure relief valve in a system opens during work
Answer:
The relief valve will open as pressure caused by a downstream load or backpressure increases high enough to force the poppet or spool open against its spring.
Explanation:
As a result of the 1934 requirement that public companies’ annual financial statements be "certified…by independent public accountants," the American Institute of Certified Public Accountants (AICPA) was permitted to establish standards governing these independent audits. Over the next few decades, the AICPA changed the organization that issues pronouncements on auditing.In 1978, the AICPA established the Auditing Standards Board (ASB) as the authoritative body responsible for issuing auditing standards. In the ASB’s Operating Policies document, the Appendix contains a history of auditing standard setting by the AICPA, including the creation of the ASB.In the Appendix to the ASB’s Operating Policies, read the section describing the creation of the Auditing Standards Board. According to this document, what are the four principal objectives of auditing standards and procedures issued by the ASB?
