Which statement about friction in a system is true? Friction converts some energy on the macroscopic scale to energy on the molecular scale.

Friction decreases the total energy of a system.

Friction increases the total energy of a system.

Friction converts some energy on the molecular scale to energy on the macroscopic scale.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

at right angles to each other

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.
