A duck in a lake swims 10 m south, 23 m west and 30 m north. The direction of the duck's displacement is A) 139 right to left degree

B) 41 right to left degree

C) 221right to left degree

D) 319 right to left degree

a.   mass number from atomic number

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.
