Magnitude of acceleration =
(change in speed) / (time for the change) .
Magnitude of Carly's acceleration =
(8 m/s) / (3 sec) = 2-2/3 m/s²
Magnitude of Soul Train's acceleration =
(30 m/s) / (8 sec) = 3.75 m/s² .
Soul Train's acceleration is about 41% greater than Carly's.
Okay, so using Kirchhoff's Loop Rule, we know the voltage drop across the entire system is 0. We can model this in a equation.
Vbatt = Vcap + Vres.
We are also told the voltage drop across the capacitor is I(t)R and voltage drop across the capacitor is q(t)/C. We can then substitute dq/dt in for I(t). We get:
Vbatt = q(t)/C + (dq/dt)R
This gets rid of the problem of I. Now we just have to get dq/dt by itself.
V - q/C = (dq/dt)*R Subtract q/C
(1/R)*(V - q/C) = dq/dt Divide by R on both sides

I think this is right, but don't quote me.
Hope this helps!

A solenoid has 18 turns per centimeter of its length. the solenoid is twisted into a circle so that it becomes shaped like a toroid, the magnetic field at the center of each turn of the toroid is mathematically given as
B=3.39292007×10^−5 T
<h3> What is the
magnetic field at the center of each turn of the toroid?</h3>
Generally, the equation for magnetic field is mathematically given as
B=\mu_0 * n *I
Where
n=18
n=1800turns/m
Therefore
B=4*\pi*10^{-7}*1800*15*10^{-3}
B=3.39292007×10^−5T
In conclusion, the magnetic field at the center of each turn of the toroid is
B=3.39292007×10^−5T
