These are some potential dangers of synthetic drug abuse
Answer:
Explanation:
Let the potential difference between plate be V .
Electrical energy lost for cyberon = V x 3e
Kinetic energy lost by cyberon = kinetic energy gain by it
V x 3e = 1/2 x 3m x vc²
For electron , the above equation becomes
V x e = 1/2 x m x ve²
Dividing the two equations
1 = vc² / ve²
vc = ve .
vc / ve = 1 .

First, you need forces attracting the Sun and Earth toward each other. That's described by Newton's law of universal gravitation.
Then you need the description of how that force causes the planet to move in a circular path. The best choice is Newton's <em>Second law</em> of motion: F = m A .
Answer:
Work done in all the three cases will be the same.
Explanation:
1) The free falling body has only one force acting on it, the gravitational force. The work done on the body = mgH (Gravitational potential energy)
2) There are two forces acting on the body going down on a frictionless inclined plane - gravity and the normal force. The gravitational potential energy will be the same. The work done due to the normal force is zero, since the direction of the force is perpendicular to the displacement. Hence, total work done on the body = mgH
3) In the case of the body swinging on the end of a string, the change in gravitational potential enrgy will once again be the same since difference in height is H. The additional force on the body is the tension due to the string. But the work done due to this force is <em>zero, </em>since the displacement of the body is perpendicular to the tension. Therefore, the total work done on the body is once again mgH.
