Force is a vector, A. Magnitude and Direction.
Answer:
b. electrons drift slowly toward the positive end of the wire
Explanation:
Motion of electrons constitutes current. According to Ohm's law, the current in the wire is directly proportional to the potential difference across the two ends of the wire.
I ∝ V
⇒V = I R
When potential difference is put, the electrons towards the positive end. Thus, option b is correct.
K= (1/2) m v^2
so 0.5*0.145*<span>1281.64=92.92J of KE</span>
Answer:
fL = fs(V/v-vs) 400000002= 40000010(331/331- vs). then find vs so easy
Answer:
e=0.374V
Explanation:
the induced voltage is the work done per unit of charge. Hence we have
however, the angle between the piece of conductor and the field is 0°. Hence
THE INDUCED VOLTAGE IS 0.374V
hope this helps!!
