We can use conservation of momentum. MaVa + MbVb = (Ma+Mb)Vf.
Plugging in values:
(.115)(35) + (.265)0 = (.380)(Vf)
Now solve for Vf.
Vf= .115*35 / .380 = 10.6 m/s
It would mostly depend on its weight
Answer with Explanation:
We are given that
Resistance,R=130 ohm
Potential difference, V=30 V
Capacitor,C=2.1pF=



a.Maximum flux



b.Maximum displacement current,
c.We have to find electric flux at t=0.5 ns






d.Displacement current at t=0.5ns


C. A combined circuit
That’s the answer
The horizontal component of the tension in the string is a centripetal force, so by Newton's second law we have
• net horizontal force

where
,
, and
is the radius of the circular path.
As shown in the diagram, we can see that

where
, so that

The vertical component of the tension counters the weight of the mass and keeps it in the same plane, so that by Newton's second law we have
• net vertical force

Solve for
:

Complete the square:

Plugging in the known quantities, we end up with

The second case has no real solution, since
for all
. This leaves us with
