We all know that the sound travels faster through solids and then liquids and then through gases.
As far as i know solids are the medium through which the sound travels fast.
But in some websites I saw that as the density increases , the velocity of the sound decreases.If this statement is correct , how come the sound travels fastest through solids (since they have higher density)
From this it is clear that not only sound as compression wave But also in the form of Shear wave travels in Solids
This makes it easier for sound to travel with higher speed in solids
Magnetism
Explanation:
Magnetism is when opposite poles of a magnet moves towards each other and towards certain types of materials.
Magnetism is a type of force that can attract or pull away other substances with some certain properties.
- It is a physical property of matter
- Objects that are magnetic typically have magnetic fields around them.
- An body that has magnetic properties will feel the impact of the force field in the vicinity of the field.
- Magnetism is as a result of the motion of electrons in an atom.
- Electric currents as a result of movement of electrons and magnetic moments gives rise to magnetism.

Answer:
Water and power come from external sources.
Explanation:
Answer:
Applied voltage should be 13.5396 kV
Explanation:
The charge stored by a capacitor when subjected to a potential difference 'v' across it's plates is given by
Solving for V we get
thus to store a charge of 0.11mC we solve for V as follows
Applying values we get
