What did you get for the internal resistance?

What did you get for the internal resistance?

3 ohms

For the current it was I^2 = PR

3 ohms

For the current it was I^2 = PR

P = I^2R rearranges to I^2 = P/R doesn't it?

thought the test was easy

From what i can remember:

1i)K+ structure was anti S U
ii) Baryon number was 0
iii)K- anti
In the B- decay the new element has 14 atomic mass 7 proton number

Particle x in the other decay was a pion neutral.

that was from q1 anyway

I got for the decay a muon neutrino to conserve lepton number. Did I read a pion as a muon?

I thought it asked for the resistances of 0.80ohms and you had to relate it to the power value and use I^2=P/R and the power was about 1.9W for 0.80ohms.

I read the value of 1.9W for 0.8ohms off the graph, people seem to be saying that they read 1.95W and 2.0W at my college, even though I am adamant that it was exactly 1.9W which gave me a value of 1.5A for the current, 1.2V for the pd across Y and 3.1ohms for the internal resistance (2sf)
