<span>The mechanical advantage to simple machines is that they allow a decreased input force to create a larger output force.

<span>Electric field repulsive for objects of like charge and attractive for opposite type of charges and for a magnet you can say that like poles repel and unlike attracts so D makes sense</span>
Here Change in Kinetic Energy
= Work Done by Friction
Therefore, substituting the
given values to the equation, we get
0.5 * m * (vFinal^2 -
vInitial^2) = µ m g * d
Therefore
0.5*( 5.90^2 - Vfinal^2 ) =
0.100*9.8*2.10
Therefore
vfinal = 5.54 m/sec

D. all of the above
Hope this helps!
Speed is just how fast the object is moving, while velocity is the speed and <em>direction </em>of the object.
edit* Direction would be something such as North, East, etc.
