Alternate current Hello!
I need solve 2 questions, I tried but im so bad at physics :(

1. If the frequency in the network is 50Hz, what is the period of this voltage?
2. The effective voltage value in the network is 230V. What is its maximum value?

I would like an explanation with a calculation for my understanding!!

Thanks in advance you all!

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
