Answer:
0.82A
Explanation:
first we resolve the resistors in parallel
i.e 1/R=1/R1+1/R2
=1/R=1/6+1/3
1/R=1/2
R=2/1=2ohms
now we resolve all resistors in series
R=R1+R2+R3
R=6+3+2(the two parallel resistors we resolved are now in series with the others)
R=11ohms
From ohm's law V=IR
I=V/R=9/11= 0.82A.
Answer:
F = K Q1 Q2 / R^2 = m g
Q1 = - Q2 = (4E12 * 1.60E-19) = 6.4E-7 coulombs
Q^2 = 4.10E-13
R^2 = 9.0E9 * 4.1E-13 / (.003 * 9.80) = 36.9E-4 / 2.94E-2
R^2 = .126
R = .35 m
Answer:
7.07 hours
Explanation:
divide the distance by the speed
so in this case, divide 672 by 95
Sally's displacement (5m forward) is 10m less than her distance traveled (15m). <em>(B)</em>
