In the diagram below, light from the Sun strikes a beach (Z). The beach sand gains heat then warms the air that is immediately above it (X) and the sand that is immediately below it (Y). The warm air rises and is replaced by cool air (W).

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.

use photo math tells u all the answers thats what i use
