The work done by the battery to charge the capacitor is equal to the electric potential energy stored in the capacitor at full charge, which is given by:
where
is the capacitance of the capacitor
is the voltage across the capacitor (which corresponds to the voltage of the battery)
By substituting the numbers into the equation, we find the work done:
Thank you for posting your Physics question here. I hope the answer helps. Upon calculating the ramp with the horizontal the answer is 20.49 Deg. Below is the solution:
Y = 7 m.
<span>r = 20 m. </span>
<span>sinA = Y/r = 7/20 = 0.35. </span>
<span>A = 20.49 Deg.</span>
It's because of the position of tectonic plates.
First we calculate the acceleration of the cart:
a = (v₂ - v₁) / (t)
a = (7 m/s - 3 m/s) / (8 s)
a = 4 m/s / 8 s
a = 0.5 m/s²
Using the Newtons Second Law:
F = m×a
F = (10 kg)(0.5 m/s²)
F = 5 N
<h2>The correct option is C</h2>
