2. (25 marks) (a) use the ideal gas law to estimate the number of air molecules in
your physics lab room, assuming all the air is n2. the room size is 150m”, the
temperature is 20°c, the pressure is latm. (b) calculate the particle density in the lab
(that is, the number of molecules per cubic meter)

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
