Im not 100% sure but I beleive the answer is :Because different celestial body's form different shapes and sized of comets and meterors
A capacitor is connected to an ac supply. increasing the frequency of the supply increases the current through the capacitor
A capacitor is a device for storing electrical energy that consists of two insulated conductors in close proximity. The parallel-plate capacitor is a simple example of such a storage device.
A capacitor (also known as a condenser) is a two-terminal passive electrical component that stores energy electrostatically in an electric field. Practical capacitors come in a variety of shapes and sizes, but they all have at least two electrical conductors (plates) separated by a dielectric (i.e., insulator).
Capacitors exist in various shapes and sizes, and their value is measured in farads (F). Capacitors are utilized in both alternating current and direct current systems.

The frequency f of the AC source is determined as 0.446 Xc.
<h3>
Frequency of the AC source</h3>
The frequency of the AC source is calculated as follows;
Xc ≡ 1/2fC
where;
- Xc is the capacitive reactance
- f is frequency
- C is capacitance
fC = 2Xc
f = 2Xc / C
f = (2Xc)/4.48
f = 0.446 Xc
Thus, the frequency f of the AC source is determined as 0.446 Xc.

Answer:
Explanation:
A solid comes into your hands with a definite shape. Think of something like a rock. It is not going to be easy to change its shape. So the answer is a solid.
Answer: Option (b) is the correct answer.
Explanation:
Kinetic energy is defined as the energy obtained by a substance due to its motion. So, when an electron or substance is moving from one point to another then the electron has acquired a motion.
Hence, this means that the electron has acquired kinetic energy.
For example, when an electron jumps from the negative to the positive terminal then it means the electron is moving. Hence, it has obtained a motion.
Thus, we can conclude that as the electron jumps from the negative to the positive terminal as the electron jumps from the negative to the positive terminal.
