Final answer:
The voltage of a hummingbird can be calculated using the charge and radius of the bird, using the formula V = k * Q / r. For a charge of 240 pc and radius of 3 cm, the voltage is 1.44 x 10^12 V.
Step-by-step explanation:
The voltage of a hummingbird can be calculated using the formula V = k * Q / r, where V is the voltage, k is the electrostatic constant (9 x 10^9 N m^2/C^2), Q is the charge, and r is the radius of the sphere. In this case, the charge of the hummingbird is 240 pc (picocoulombs) and the radius of the sphere is 3 cm. So, the voltage can be calculated as:
V = (9 x 10^9 N m^2/C^2) * (240 x 10^-12 C) / (0.03 m)
V = 1.44 x 10^12 V
