A series LC circuit contains a 100 mH inductor, a 36.0 mF capacitor and a 12 V battery. The period of the electromagnetic oscillations in the circuit is
1. 0.0227 s.
2. 1750 s.
3. 105 s.
4. 2.26 s.
5. 0.376 s.
f= 1/ 2*π *√L *C
L =100mH
C= 36uF
so,,f = 2.65...
A circuit contains two inductors of 6.0 mH inductance in series placed in parallel with an inductor of 8.0 mH inductance. After one of the 6.0 mH inductors burns out, the repair person wants to replace all three inductors with one inductor of equivalent inductance. What inductance should she...
I would like to verify these answers please..
What is the inductance of a series RL circuit in which R=1.0 K ohms if the current increases to 1/3 of it's final value in 30 Ms (M is the greek symbol Mu).
Is the answer 30 (none of these) or is it 74mH?? I calculated 74mH
i(t) = I...
Use ampere's law to determine the magnetic field (a) inside and (b) outside a toroid, which is like a solenoid bent into the shape of a circle.
Here is my work..
IS MY WORK CORRECT?
a.) B(2PIr)=MoIenc
and I found that B=MoNI/2pir
b.) the magnetic field is 0 outside the loop
There is supposed to be a picture, but it won't generate on the website. Go to this link to see the picture. http://answerboard.cramster.com/physics-topic-5-146405-0.aspx
A hungry bear weighing 750 N walks out on a beam in an attempt to retrieve a basket of food hanging at the end of the beam. The beam is uniform, weighs 200 N, and is 5.80 m long; the basket weighs 80.0 N.

The magnitude of the net force exerted in the x direction on a 3.15 kg particle varies in time as shown in the figure below.
There is a graph that is supposed to be here. The y-axis is F(N) and the x-axis is t(s)
It starts from the orgin then goes to point (2,4), then to (3,4), then ends at...
for part A I found the answer to be 12 (4+4+4)
for part B I did I=mv which came out to v=3.8m/s
I am stuck on part c. I thought I am supposed to use I=m(vf-vi) but I keep getting a wrong answer.
And for part d I used I=f(tf-ti) and found the answer to be 2.4N
So I need part c!
