I have to conduct a lab concerning inverters. I'm using a 7404 hex inverter IC, 6 LED's with 150Ω resisters, and 1 logic switch. Can someone tone it down a little bit so I can undersetand what the lab is wanting me to do? And what does the image on the second page show (Figure 3-7 and 3-8)...

If you take a look at the attachment that I have posted, you will see 4 wave diagrams labeled A, B, C, D, respectively. My objective to is to answer the questions after the A-D diagrams. The first one is a AND logic gate with A and B. So how would I combine A and B. Do I draw only the highs of...

I need help with this question: A woman gives birth to a son. Two years later, she gives birth to another son. What is the probability that her third child will be a girl? Explain your reasoning. I think it is 50% chance that it will be a girl because when you use the punnet square the...

Why would time stop if you travel at the speed of light?

Do you also need a degree in chemistry?

What are you talking about? When I typed "degrees" I mean like Master's or Bachelor's degree not like temperature.

I mean by like a physicist who specializes themselves in war. For example, inventing guns or anything that is used in war. A warfare physicist also studies nuclear physics and related type physics. If you can't find anything to tell me about warfare physicists. Can you tell what degrees do...

What degrees do I need to be a warfare physicist. I know I need a Ph.D. in physics. What else do you need? Do need anything in Chemistry? Do I need something in math too? Please give all the details you can think of about my career. :smile:

Can someone explain the equation G_{\mu\nu}+\Lambda g_ {\mulnu}={8\ pi G\over c^4} T_{\mu\nu}\ by Albert Einstein?

Thanks for the help! :)

If the question meant this \frac{x+3}{3}, I would add first then divide?

I think the question meant \frac{x+3}{3}, instead of x+\frac{3}{3}.

I think I got the hang of this now!

The funny thing is on the sample answer it doesn't follow PEMDAS. Do you think the other questions like that will follow PEMDAS? Because when I followed PEMDAS to do the problem, there wasn't a choice for my answer which was 4. :rolleyes:

On my assesment it had a question that said x+3/3, when x=3. I thought you do 3/3 first so did the teacher, but when he looke at the answer key it showed you were suppose to do 3+3 then divide by 3. And also on my test booklet, it doesn't have 4 which is the answer if you do it with PEMDAS...
