Magnetic field lines come from North pole and goes to south pole, as there are two north poles, they will be going from both the poles.
In short, Your Answer would be Option 4
Hope this helps!
The answer is 60%. If you divide the 9 and 5, you will get 0.6. So you just move the decimal point to the right twice. (:
In the second 30 mins, the speed should be 20 + 1.5 = 21.5 km/h
So S = 21.5 * 30/60 = 10.75 km
Answer:
by using it in a such place or thing which needs it or which can work with it
Use Newton's second law and the free body diagram to determine the net force and acceleration of an object. In this unit, the forces acting on the object were always directed in one dimension.
The object may have been subjected to both horizontal and vertical forces but there was no single force directed both horizontally and vertically. Moreover, when free-body diagram analysis was performed, the net force was either horizontal or vertical, never both horizontal and vertical.
Times have changed and we are ready for situations involving two-dimensional forces. In this unit, we explore the effects of forces acting at an angle to the horizontal. This makes the force act in two dimensions, horizontal and vertical. In such situations, as always in situations involving one-dimensional network forces, Newton's second law applies.
