At Divergent boundary, Crust is created.
At Convergent boundary, Crust is destroyed.
At Transform boundary, Crust is neither created nor destroyed.
<h3>What occurs at Divergent, Convergent and Transform boundary?</h3>
A divergent boundary occurs when two tectonic plates move away from each other. At this boundary, new oceanic crust is created.
Convergent boundaries are those boundaries where two plates are pushing into each other. These boundaries are pushing one of the plates under the other and back into the mantle to melt.
Transform boundaries are places where plates slide sideways past each other. At this boundary, Crust is neither created nor destroyed.

Answer:
- The gravity does a work of - 117.6 Joules.
- The tension does not do work as the force is perpendicular to the direction of motion at any point in the trajectory.
Explanation:
The work done by the gravity simply is the difference in gravitational potential energy multiplied by -1:
where m is the mass of the ball, g is the acceleration due to gravity, 
is the final height and 
is the initial height.
So, if the radius is 2.00 m, then the difference of height will be 4 meters:
As the tension is perpendicular to the velocity of the ball, the force is always perpendicular to the direction of motion. So, the differential of work will be:
Energy in a spring:
E = 0.5 * k * x²
k spring constant = 800 n/m
x stretch of the spring = 5 cm = 0.05 m
E = 0.5 * 800 * 0.05² = 1
A complex entity involving the Earth's biosphere, atmosphere, oceans, and soil; the totality constituting a feedback or cybernetic system which seeks an optimal physical and chemical environment for life on this planet
