I am a college sophomore getting a degree in physics. I just got an HP touchsmart tablet PC. How do the programs like MATLAB respond to the tablet input features (math input panel). Is there a special version that let's me do cool things such as straightening my lines and drawing perfect...

Resolved, I was "overthinking it". Actually I thinks its an ambiguous question but that's normal for textbooks.

Hello Physics Forum! I'm happy to join you. I would like to replace my distracting TV watching with something to keep me focused on my goals. My idea is to read stories about scientists. Please suggest books that tell really personal stories about scientists. They need to have character...

It wouldn't be the first time. The definition of a "real" battery is that the potential across it's terminals is not equal to the emf. Thats why the question is worded with the key phrase "voltage across the terminals". The statement appears to declare that this voltage across the terminals is...

The V in "watts=i*V" is the real V (Vr) not the emf. The battery is not producing 100W at 12V its producing 100W and its emf is 12V. To answer "what is the constant current?". Thats the missing value (i). I don't know where to go from here but I think its different equations. There is a good...

Homework Statement A car battery with 12V EMF charged to 120amp hours. Assume potential difference across terminals is constant. How long can the battery deliver energy at a rate of 100Watts. Missing is current (i), internat resistance (r), and real voltage (Vr)Homework Equations (Amp...
