Thank you.

Hello I have a circuit. When I power the circuit with a power supply, the power supply reads 5V and 0.025A. This gives me the P=IV=0.125W. Is this the same as 0.125W per second? I want to power this circuit with a Li-Ion battery that is rated 5V and 3200mAh. How long will my battery run...

Thanks. I'm going to redo the circuit whenever I can. So from what I've seen here, my calculations and understanding of the gain is incorrect. Let me see if I can redo my math.

I'm sorry I meant to write 15.8k. I did try a 2Mohm resistance across the capacitor. I'm still puzzled by the gain difference.

For the above op amp circuit: Vin= squarewave with 10Vpp and 1kHz. C=0.01uF. Vcc and -Vcc is 15V and -15V. Using the above specs, I calculate R using these equations: Requirement: Create a triangle wave with output voltage Vo to be 10Vpp. This is a gain of 1. Using the above, I find...

Homework Statement y(n)=x(4n+1). Is this system T.I or NOT T.I The professor marked this question wrong for my homework. He says it's NOT time invariant. I proved it is time invariant. Homework Equations System is time invariant if a shift in time in input results in the same shift in time...

ok I interpreted my data wrong. Forget what I originally posted. Here's what I got for my data. For resistor ranging from 300 to 15K ohms, the voltage ranged from 6.07-6.18V. It seems that the zener diode is working in breakdown voltage and holds almost constant voltage for a wide range of...

The following link is a picture of my zener diode set up with variable load resistor. The Source is 15VDC and the first resistor is a constant 330 ohm. When I use 470ohm up to 15Kohm for the Load resistor RL, I get a 6V voltage drop across the diode. However, when I go down to 330 ohm for RL...

Can I bump this to the top? Is this in the right section, introductory physics, or should I post this in the advanced physics section.

Homework Statement This is a problem straight from my homework. Imagine that you have a box that emits quantons that have a definite but unknown spin state. If we run quantons from this box through an Stern Gerlach (z-axis) device, we find that 20 percent of the electrons come out the plus...

Ok here is what I've concluded about the velocity of the ball and the astronaut's mass. The velocity of the ball must be extremely high (close to c=1) to balance out the fact the the astronaut has velocity 0 in the final momentum in the x direction. Also the astronaut's mass in the beginning is...

Is my handwriting/work too sloppy? I will try to make it much neater.

No actually the question says it is the mass of the ball that does not change. Here is my answer. I'm about 90% sure of it. Can you please check it out and see if what I did is good?

OH I see. The mass of the astronaut in the final momentum is not 100kg like I thought. Have to give it the Variable M. Ok This will be a piece of cake then. Thanks.

Hello. I've uploaded the question onto pictures and linked them. I hope this method of asking a question works. I'm trying to find the mass of the ball, but I get the square root of a negative number. Can someone take a look to see if I'm doing this problem correctly?
