Answer:
224 J
Explanation:
Step one:
given data
Force applied = 22.4 N
distance = 10 meters
<u>Required:</u>
the work done
Step two:
The expression for the work done is
WD= force*distance
substitute
WD= 22.4*10
WD= 224 J
If that's the case, then
50 units = 0.55 x the input energy
Divide each side by 0.55 :
50 units/0.55 = the input energy =
<em> 90 and 10/11 units</em>
B. Magnetic force-attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. The magnetic force between two moving charges
may be described as the effect exerted upon either charge by a magnetic field created by the other.
