Voltage Vaporization: 2.5C Charge, 3.3 MJ Energy, 1.32 MV Potential Diff

AI Thread Summary
A lightning flash transfers 2.5 coulombs of charge and 3.3 megajoules of energy to the Earth, resulting in a potential difference of 1.32 megavolts. The discussion seeks to determine how much water can be boiled and vaporized from room temperature using this energy. Participants are looking for equations related to specific heat and heat of vaporization to solve this problem. There is a lack of initial attempts at a solution, indicating a need for guidance on the relevant physics concepts. Understanding these concepts is essential for calculating the amount of water affected by the lightning energy.

Do you know anything about specific heat and heat of vaporization?
 
nope
just basic energy and voltage equations
 
anyone?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
