Answer:
When an electrical current passes through a wire, a magnetic field is generated around it. Likewise, if the magnetic field around a wire is changed ( for example by rotating a coil inside a stationary manger), electricity will move through the wire.
Speed = distance / time
3.4cm / 0.1s = 34 cm/sec

Answer:570 N
Explanation:
Given
one rope applies a force of 475 N in west direction
other applies a force of 315 N in south direction
So both forces are at an angle of 
Net resultant of two forces is
and the resultant will be an angle of \theta with 475 Newton force
So replacing two force we can apply a force of magnitude of 570 N at angle of 
with west
