Answer:

Explanation:
As we know that

E = 1.8 kV/mm
now we know that electric field between the plated of capacitor is given as

now we will have



now we have

now we have area of the plates of capacitor



Answer:
I believe that the crab would have 14 arms if the octopus had 12 arms
Explanation:
We are given a series circuit with two light bulbs. In this case, the light bulbs act as resistors in series and the total resistance is:

That is the sum of all the resistances in series in the circuit. To determine the voltage we can use Ohm's law:

Where "R" is the total resistance and "I" is the current in the circuit. Replacing we get:
Answer:
Explanation:
It can be increased by: increasing the rate of rotation. Increasing the strength of the magnetic field. Increasing the number of turns on the coil.
