Answer:

) You must create a Low Pass Filter for an audio amplifier. You must pass 10khz and block

60khz. In designing this, you must choose a cutoff frequency exactly half way between

these two frequencies. In addition, you must use a 0.2uF capacitor in you LPF circuit.

Given these criteria, analyze this circuit, and determine the necessary resistor value in

Ohms. Find the output Voltage at both ends of the spectrum. Based on your results, is

this a good design? NOTE: You MUST show your work (when using MS Word, choose

“Insert”--- “Equation”). (6 marks)

a. Solve for fc

b. Solve for R

c. Solve for Vout at 10khz

d. Solve for Vout at 60khz

e. Good design> (yes or no with an explanation)

Which of the following types of protective equipment protects workers who are passing by from stray sparks or metal while anothe

lawyer [7]

A protective equipment which protects workers who are passing by from stray sparks or metal while another worker is welding is: E. Welding Screens.

A wielder refers to an individual who is saddled with responsibility of joining two or more metals together by wielding.

During the process of wielding, sparks and minute metallic objects are produced, which are usually hazardous to both the wielder and other workers within the vicinity.

Hence, the following protective equipment are meant to be worn or used directly by a wielder (worker) who is wielding:

Visors.

Goggles.

Protective clothing.

Dark walls.

However, a protective equipment which protects other workers who are passing by from stray sparks or metallic objects while wielder (worker) is welding is referred to as welding screens.

What is the present value of the future receipts of $2,000, 5 years from now at 10% compounded annually?

Elden [556K]

Answer:

P = $ 766.28

Explanation:

present value = ?

Future value = $ 2000

time = 5 years

compounded annually at the rate of = 10 %

$A = P + P(1+\dfrac{r}{100})^t$

$2000 = P + P(1+\dfrac{10}{100})^5$

2000 = P + 1.61 P

2.61 P = 2000

P = $ 766.28

hence, the present value of amount invested to get the future value of $2000 is equal to P = $ 766.28

1. If a bolt is size 1/2" or larger, then its corresponding wrench size should be____ larger than the bolt size

Mrac [35]

Answer:

C. 1/4"
B. 3/16"

Explanation:

1. For hex bolts, lag bolts, and square bolts, the wrench size is 1/4" larger than the bolt size for 1/2" and 9/16" bolts. For 5/8" bolts and larger, the wrench size is <em>50% larger than the bolt size</em>.

2. For 7/16" bolts, the wrench size is 5/8", so is 3/16" larger than the bolt. This holds down to 1/4" bolts, where the wrench size may be 3/8" or 7/16".
