My niece who will be 1 year old in a few weeks will be sitting down or standing or be in someone's arms and will just randomly laugh at thin air. She'll basically be laughing at nothing. Her grandpa is deceased and I can't help but think that it is him because in life he was a goofball. I don't believe in Sylvia Browne either. None of the other babies in my family have done this. Is it paranormal or no?

I know how many moles KHP I used and I know how many moles of base I have. I also have the mass.....or was it volume? I can't remember. Anyway, how do I find the molarity of my base solution?

I am only 23 but a masters is 4 years and i may have to do a foundation year which would mean i wouldnt graduate until i was 29 or 30 because i am at college at the mo and wont be applying until 2008 for entry in 2009. I would still have 30 years or so employment. What do you think, am i too old? Is it a good career? Is it more of a male career and could i face difficulties as a woman, i am particulalry interested in Offhsore Engineering.

Thanks guys and gals.

a) 246.94Hz, 220.00Hz, 261.63Hz, and H.

This is supposed to be a composer, but I don't know how.

b) 440.00Hz, 523.25Hz, and 659.26Hz

How are these three frequencies related?

I am trying to capture I/O's for devices like valves, pumps with and without vfd, motors with overload...things like that.

I also notice on previous projects from other engineers, the I/O's they had captured for pumps had 2in/out and analog 1in/out. I dont understand really why there would be 2 in/out for a pump. I know that an analog in/out would mean that they have something controlling the motor through a VFD.

So, if anyone can tell me how many I/O's for each devices I had mentioned above and describe the functional of each I/O, I would appreciate it.

Oh, and the system I'm working on is a CIP system (clean in place syst) and what the pump does it pumps water from a supply tank and is controlled by a VFD. Another pump is a return pump with out a VFD. We also have a motor in the system, that is an agitator triggered through a limit switch. So what I'm really looking for are the rule of thumb from experienced engineers when they try to capture I/O's of a system.

I know Mars is and know which one it is, but i looked at an onliune star chart and saw Saturn was also but i am not sure if i have seen it or not. I have seen a star/planet left and up a bit of Mars (check my detailed terminology!!) it's not twinkling and i was wondering if this is Saturn.

Thanks

The relationship E= (1.24 *10 ^3) / λ, where E is the energy of a photon in electron colds and λ is the wavelength in nanometres, is a handy form of the equation E = (h*c) / λ. Substitute E=(h*c) / λ and make any necessary unit conversions, to show that E= (1.24*10^3) / λ, is valid for nanometres and electron volts.

Basically, i have to solve for h*c.. i did that and i got:

hc= (6.63 * 10 ^-34 J/s) * (3.0 * 10^8 m/s)
= 1.989 * 10 ^ -25 J/m

I now need to convert that into nanometres and electron volts (eV).
1 nm = 1.0 * 10^9 m and 1eV = 1.60 * 10^ -19 J

I'm having difficulty...anyone know how to solve this?
