A direct-current (DC) generator is a rotating machine that supplies an electrical output with unidirectional voltage and current. ... The field is produced by direct current in field coils or by permanent magnets on the stator. The output, or armature, windings are placed in slots in the cylindrical iron rotor.
Answer:
Explanation:
charge, q = 1.6 x 10^-19 C
distance, r = 911 nm = 911 x 10^-9 m
The Coulomb's force is given by


F = 2.78 x 10^-16 N
The force between the electron and the proton is 2.78 x 10^-16 N.
The answer is 8 because multiplying 7 and 8 is 56
Since the ball was not moving before it let Aiden's hand, the formula used to calculate the acceleration is

, where a is acceleration, v is velocity and t is the time. We put them in the formula and get

The acceleration is 490 m/s^2
