Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. The maximum rate of charge flow in a lightning bolt is about 20,000 C/s this lasts for 100 μs or less. 1.How much charge flows between the ground and the cloud in this time? (Q= ? C) 2.How many electrons flow during this time? (n_e = ? )
Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. The maximum rate of charge flow in a lightning bolt is about 20,000C/s; this lasts for 100μs or less.
During a thunderstorm, a lightning "bolt" carries current between a cloud and the ground below. If a particular bolt carries a total charge of 15 C in 1.5 ms, what is the magnitude of the current? A How many electrons are involved in this process? electrons
What is the answer and formula to find Part B? <HW 1: Electric Charges and Fields Exercise 21.2 Part A How much charge flows between the ground and the cloud in this time? Express your answer using three significant figures Constants Lightning occurs when there is a flow of electric charge (principally e and a thundercloud. The maximum rate of charge flow in a lightning bolt is about 20,000 C/s; this lasts for 100 us or less. s) between the...
QUESTION 3 A lightning bolt might carry a current of 100 A and last for about 31 ms, as shown in the figure below. Determine the amount of charge (in coulombs) that is exchanged between ground and cloud is such a lightning bolt. (Enter your answer as a number without the units.) +i=10°
A lightning bolt has a current of 40,000 A and lasts for 50 x 10-6 seconds (50 us). How much charge (in Coulombs) has flowed in this bolt? E only, to two significant figures.
5. During a random lightning strike from a cloud to the ground, a current of 25,000 A lasts for 40 (1 point) us. How much charge is transferred from the cloud to earth during that strike? 02.0 C 01.6 C 01.0 C 02.5 C 6. The graphs show the temperature dependence of resistance for two materials. How do the (1 point) materials compare? Material A Material B OMaterial A is a typical conductor, whereas material B is a typical insulator...
Problems: (Show all your work) 1. A lightning stroke lasts 0.05 s and involves a flow of 100C. What is the current? A current of 0.7 A goes through an electric motor for 1 min. how many coulombs of charge flow through it during that time? 2.
#21 please During a lightning flash, -15 C of charge moves through a potential difference of 8.0 Times 10^7 V. Determine the change electric potential energy of the field-charge system. Sketch a V-versus-position graph for the electric potential created by a point-like object with charge +Q. Using the same set of axes, draw a graph for an object with charge +2 Q and for an object with charge - 2Q. A horizontal distance d separates two objects each with charge...
11a) A heavy summer rain has just spoiled a fun game of frisbee between you and your friends. As you rush to leave, a bolt of lightning strikes a tree on the other side of the field. Lightning is a form of electrical discharge that occurs when the electric field in a region between the ground and the clouds ionizes the air. You happen to know that a bolt of lightning can unleash about five hundred million joules of energy,...
