Answer:
The value of P(5)=0.09264
Explanation:
The equation given is;
The value of P(5)=0.09264
Answer:
t= 9.79 hr
Explanation:
Given that
V= 3.5 V
Capacity= 4 Amp-hour
We know that
V= IR
V= Voltage
I =Current
R=Resistance
V = I R
The total voltage on the batteries will be 2 V
2 x 3.5 = I x 10
I= 0.7 A
We know that Power P
P = V I
P = 0.7 x 7
P =4.9 W
4 A.h and 12 volt power supply = 4 x 12 = 48 W.hr
So time of drain t
4.9 t = 48
t= 9.79 hr
Answer:
t=13.49 min
Explanation:
Given that
I=300 A
A= 0.21 cm²
L= 0.85 m
Number of charge carriers per unit volume = 8.49 x 10²⁸ m⁻³.
We know speed of the electron given as
V=J/ne
J= I/A
So
V=I/neA
V=0.00105 m/s
lets take t is the time when electron travels from car battery to the starting motor
t = L/V
t=809.52 s
t=13.49 min
