An electrical <span>current is </span>caused<span> by </span>flow<span> of free electrons from one atom to another. </span>
<span>It's another energy balance equation, though: energy to start with is the same as energy that you end with. Suppose that we start a distance r0 from the Earth and end a distance r1 from the Moon, then the energy balance gives:
1 v02 - G M / r0 - G m / (D - r0) = 1 v12 - G M / (D - r1) - G m / r1
...where m is the moon's mass.
One simple limit takes D ? ? and 1 v02 ? G M / r0 (the escape velocity equation), to yield:
1 v12 ? G M / r1
v1 ? ?( 2 G M / r1 ) = 2377 m/s.</span>
The resultant of the two forces, vertical ground reaction force and frictional force is 1907.8784 N.
<h3>What is triangle law of vectors?</h3>
When two vectors are represented by magnitude and direction, then its resultant is given by the closing side of the triangle.
Given the vertical ground reaction force N = 2000N and horizontal frictional force F = 600N, then the resultant will be
R = √[(2000)² + (600)²]
R = 1907.8784 N
Thus the resultant force is 1907.8784 N
