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)
Explanation:
Width * Length * Thickness * Density = Weight.
48″ * 96″ * . 1875″ * 0.284 lb/in3 = 245 lb.
Answer:
A. smallest wire is No. 12
Answer:
Option B: An MSDS
Explanation:
A dictionary is used to check up the meaning of general words and not for checking if a substance being used is hazardous. Option A is wrong.
MSDS means "Material Safety Data Sheet" and it contains documents with information that relates to occupational health & safety for checking various substances and products. Thus, option B is correct.
SAE stands for Society of Automotive Engineering and their standards pertain to mainly Automobiles. Thus option C is wrong.
EPA guidelines are mainly for checking facility and environmental health and safety compliance. Thus, option D is wrong.
Answer:
Explanation:
Given: Pressure of a fluid column ΔP=ρgΔh
Density of water (ρ) = 1000 kg/m^3
Acceleration of gravity (g) = 9.8 m/sec^2
Δh = difference in height / elevation of water tower and tap
= 50 - 10
= 40
Substitute back into equation:
Pressure = 1000*9.8*40
= 392000 N/m^2
The answer is D.
