AI Thread Summary
To determine the number of electrons transferred by a lightning bolt that delivers 24 C of charge, the equation Q = ne is used, where Q is the total charge, n is the number of electrons, and e is the charge of a single electron (−1.60218 × 10−19 C). The confusion arises regarding whether to use the positive or negative charge of the electron in calculations. Typically, a positive charge indicates a deficit of electrons, while a negative charge indicates an excess. The correct approach is to use the absolute value of the electron's charge for calculations. Understanding these principles clarifies how to compute the number of electrons transferred in such scenarios.

Homework Statement



A strong lightning bolt transfers about 24 C
to Earth.
How many electrons are transferred? The
charge on an electron is −1.60218 × 10−19 C.

Homework Equations



Q=ne

The Attempt at a Solution



i wasnt sure which charge to use. i pluged in the #s given plus the elementary charge using -, since its an electron. then i tried adding it and a couple of other things... i got confused! thx!
 
Physics news on Phys.org
Ne = q/e
 
with these types of questions, they usually ask whether the particle has a defecit/ excess of electrons, usually if the charge is positive that means that it has a defecit of electrons, likewise if the charge is negative, there are an excess amount of electrons
 

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 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
