Keisha is making a table summarizing her notes about the different types of investigation. she places an x into the table to show which steps are included in a descriptive investigation. part of the table is shown.
where should keisha place an x?
in box 1 only
in box 2 only
in box 2, 3, and 4
in box 1, 2, 3, and 4

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

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.
