Answer:17.5
Explanation: (0.5 meters)(35 Joules) =
Hydrogen is an Alkali Metal side because it has ns1 electron configuration like the alkali metals. elements are very reactive
Answer:
Explanation:
Mechanical energy = Kinetic energy + Potential energy
We shall calculate mechanical energy at different points of time .
Time Kinetic energy Potential energy mechanical energy
0 0 4 4
2 2 2 4
4 4 0 4
6 2 2 4
8 0 4 4
10 2 2 4
and so on ........
Hence we see that total mechanical energy is constant at the value of 4
at all time .
