Power can be calculate through the equation,
Power = Force x velocity
It should be noted that velocity is calculated by dividing displacement by time. Thus, from the given in this item we can calculate for the power.
Power = (120 lb) x (12 ft/9 s)
<em> </em><span><em>Power = 160 lb.ft/s</em></span>
Answer:
The input force (effort) is the amount of effort used to push down on a rod, or pull on a rope in order to move the weight. In this example, the force the little guy is using to pull the elephant is the input force.

Answer:
0.1040512455 N

0.05925 N

Explanation:
I = Current
B = Magnetic field
Separation between end points is

Effective force is given by

The force is 0.1040512455 N

The angle the force makes is given by

The direction is 

The force is 0.05925 N


The direction is 
D.
This is an accordance with Newton's First Law of Motion, stating that objects in motion remain in motion and objects at rest remain at rest unless acted upon by an external force.
