An electron is carried from the positive terminal to the negative terminal of a 9 v battery. How much work is required in carryi
ng this electron?
1 answer:
Answer:
The work required for the electron is 
Explanation:
The work of the electron is calculated in the equation:


C= Coulomb = s*A
V= Volts = 
W=

For resistance we have R=ρ l/a
thus for conductance we have K=σ a/l
conductance,K=1/R
conductivity,σ =1/ρ
σ = .80 Ω-1 cm-1
l =9 cm
a = 3 cm²
K=.80 ×3/9
=0.26 Ω-1
Answer:
Friction always acts opposite to the motion.
Answer:
let m be the mass of the object, K be the force constant and Fs be the force by the spring on the mass.
PE=mgh
180=0.5*10*h
180=5h
h=180/5=36 m
