An unknown element has an atomic number of 44. Identify the element’s symbol and the symbols of two other elements that have similar properties.

the largest known star in the universe is uy scuti, a hypergiant with a radius around 1,700 times larger than the

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.
