Homework Statement Design a 4 input priority encoder with a 4 to 16 decoder and a 8 to 1 multiplexer. Homework Equations Priority encoder is where when the highest priority bit is equal to a logical "1", then the rest of the lower priority input are ignored.The Attempt at a Solution For the...

Maybe you want to redo your calculation for your nodal analysis at point Vx Your equation should be 5 = i1 + i3 + i4 (since i2 = i3 + i4), but I see 4 terms in your equation, which should only be 3 terms?

Homework Statement VBE=0.7V The transistor in the circuit of Fig. P5.69 has a very high 0. Find the highest value of VB for which the transistor still operates in the active mode. Homework Equations VC>VB IC=IE (since IB is approximated to zero due to high beta) EDIT: IE= [VE-0]/1k (VB -...

EDIT: I've come up to R1/(R1 + R2) > R1 , where R2 > 0 since R1+R2>R1 , then when R1 is divided by R1+R2(a larger number), surely R1/(R1+R2) is lesser than the original number. now I can't have any reasoning that when I multiply R1/(R1+R2) by R2, tht this inequality still stands. EDIT: I...

Homework Statement Prove that the equivalent resistance in a parallel circuit with 2 resistors with resistance R1 and R2 is always lesser than the resistance of either resistor. Homework Equations Rt= (R1 x R2)/(R1 + R2) The Attempt at a Solution I tried starting from R1 + R2...

Well what about if there is a negative and and a positive? Say m1 = -1 and m2 = 2 If we followed the formula, I would get a tanθ, However if I were to swap them, I would instead get a negative tanθ. Or does this matter?

Homework Statement Find the equations of both the straight lines that are inclined at an angle of 45 ° with straight line 2x + y - 3 = 0 and passing through the point (-1 , 4) Homework Equations tan θ = (m1 - m2)/(1+ m1m2) The Attempt at a Solution If I were to use the equation above, how...

Homework Statement A speck of dust is 3cm from the center of a glass sphere with radius of 5cm. If the glass sphere is placed in a tank of glycerin with a refractive index of 1.47, find the image distance, as viewed along the diameter through the speck of dust from the far side. Refractive...

I'm sorry for the poorly-phrased question, give me another try at this. An intermediate ion with tertiary carbocation is the most stable right? This is because it has the most alkyl group attached to it, thus making it stable. There is also a mention that the more stable the intermediate...

In alkenes, the more alkyl groups you're attached to means you are more energetically stable, and that we know the reactivity increases as the stability of the intermediate carbocation increases (with tertiary the most stable) I'm puzzled by this relationship, how is it that when it is more...

Yes, and I would like to add that the majority of my country's people would agree with you. The country is going through brain drain, there's no helping it. Anyhow, can you give a brief explanation as to why the answer is D? Because I remember the difference of frequency between two energy...

wouldn't that be 5 valence electrons when there's only 3 chlorine attached and the charge is negative 1

hmmm, let me quote the whole question to avoid any miscommunication. Tin (Sn) is an element of Group 14. What type of hybrid orbitals would tin use in SnCl3 (-1) A. sp B. sp2 C. sp3 D. sp3d I'm not sure if this changes anything but I hope there's an answer to this. PS: one more...

I just had my exam today, so I had this question that is, what is the type of hybridization which occurs in SnCl3 - , my answer is sp2 hybridization because I thought that the last electron left wouldn't be hybridized. Am I correct?

I'm trying to understand the qualitative relationship of voltage and the a.c. through a pure inductor. My books says that to maintain the current in the inductor, the voltage across the inductor provided by the a.c. supply must be equal to the back emf but in the opposite direction. I'm quite...
