Use the law of conservation of energy.
Potential energy of the object with mass m at the height h is equal to:
<span> E=mgh
</span>
and the potential energy of a spring is equal to <span> <span>E<span>spring</span></span>=<span>1/2</span>k<span>x^2</span></span><span>
where k = spring constant, x = displacement
Since all the gravitational potential energy will be transformed to the spring potential energy, its quite easy to figure out the displacement from this two equations
E= mgh
E= 2*9.8*0.2
E= 3.92
E=1/2kx^2
E=1/2*1225*X^2
3.92*2=1225*X^2
0.0064=X^2
X=0.08 m or 8 cm</span>
Answer:
Nuclear fusion reactions produce more energy.( basic difference)
Explanation:
Nuclear fusion reactions are different from nuclear fusion reactions :- In nuclear fission one heavy and unstable nuclear breaks into two parts(smaller) and produce energy( very high energy than normal reaction). whereas in nuclear fusion two small and unstable nuclei fuse and produce very high amount of energy( even higher than nuclear fusion).
