The equivalent capacitance () of an electrical circuit containing four capacitors which are connected in parallel is equal to: A. 21 F.
Basically, the components of an electrical circuit can be connected or arranged in two forms and these are;
- Series circuit
- Parallel circuit
A parallel circuit can be defined as an electrical circuit with the same potential difference (voltage) across its terminals. This ultimately implies that, the equivalent capacitance () of two (2) capacitors which are connected in parallel is equal to the sum of the individual (each) capacitances.
Mathematically, the equivalent capacitance () of an electrical circuit containing four capacitors which are connected in parallel is given by this formula:
Ceq = C₁ + C₂ + C₃ + C₄
Substituting the given parameters into the formula, we have;
Ceq = 10 F + 3 F + 7 F + 1 F
Equivalent capacitance, Ceq = 21 F.

Answer:
Probability of tunneling is
Solution:
As per the question:
Velocity of the tennis ball, v = 120 mph = 54 m/s
Mass of the tennis ball, m = 100 g = 0.1 kg
Thickness of the tennis ball, t = 2.0 mm =
Max velocity of the tennis ball, = 89 m/s
Now,
The maximum kinetic energy of the tennis ball is given by:
Kinetic energy of the tennis ball, KE' =
Now, the distance the ball can penetrate to is given by:
Thus
Now,
We can calculate the tunneling probability as:
Taking log on both the sides:
