-0 m/s
- average velocity=displacement/time
- the runners displacement is zero so her average velocity must be zero
Answer:
it increases the amplitude of the wave as it propagates.
Explanation:
Answer:
270 μA
Explanation:
Use the magnetic field due to long, straight wire and solve for current I.


plug in the values

= 2.7×10^{-4)×10^6
=270 μA
The current that flows in the heart is 270 μA
B. Reversing the current direction will cause the force deflecting the
wire to be perpendicular to the magnetic field but in the opposite
direction.
