The energy in the capacitor at the instant after the switch is closed, based on the potential across the capacitor is 31 mJ
<h3>What is the energy amount in the capacitor?</h3>
Because total energy is constant, this can be found by the formula:
= Initial energy in capacitor - Energy in inductor
The initial energy in the capacitor is:
= 0.5 x 4 x 10⁻⁶ x 200²
= 0.08J
The energy in the inductor is:
= 0.5 x 0.2 x 0.7²
= 0.049
The energy in the capacitor at that instant is:
= 0.08 - 0.049
=0.031 j
= 31 J

Explanation: Hope this helped! :)
The problems caused by urbanization are;
- loss of aesthetic and cultural space
- increased high temperatures (heat-island effect)
- increased storm-water run-off, flooding, and pollution of waterways
<h3>What is Urbanization?</h3>
Urbanization is defined as the process whereby large numbers of people become permanently concentrated in relatively small areas thereby forming cities. The features that depict the problems caused by urbanization are;
- loss of aesthetic and cultural space
- increased high temperatures (heat-island effect)
- increased storm-water run-off, flooding, and pollution of waterways
