Which of these is an example of electromagnetic induction? A current passing through a resistor uses power IR2. A current throug
h a wire produces a magnetic field. A changing magnetic field induces an electromotive force. A moving charge produces a magnetic and electric field
1 answer:
Well as a pretty direct hint, recall that the word "induction" comes from the fact that electric fields are "induced" by (changing) magnetic fields

Speed is equal to distance traveled divided by the time. So it's 3.5 m/s
Answer:
below
Explanation:
Net accelerating force becomes 12-8 = 4 N
F = ma
4 = 2 * a
a = 2 m/s^2
Unlike acceleration and velocity, speed does not need to specify the direction of motion. Speed is a scalar quality.
