1.1 a rectangular block of wood has dimensions
240 mm x 20.5 cm x 0.040 m. calculate its
volume in cm

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

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.
