here the charge density of metal plate is given as
now the electric field is given Gauss law
now here E = constant
so we will have
Since total area on both sides of plate will be double and becomes 2A
Now if we will find the electric field inside the metal plate
Then as we know that total charge inside the plate will always be zero
so we have
Answer: is a term generally covering any funding for scientific research, in the areas of both "hard" science and technology and social science. The term often connotes funding obtained through a competitive process, in which potential research projects are evaluated and only the most promising receive funding. Such processes, which are run by government, corporations or foundations, allocate scarce funds.
Explanation:
Answer:
At the molecular level, materials are held together by bonds, which act like springs for small displacements from the equilibrium spacing between neighboring atoms. Push the atoms close, the bond pushes back to keep them apart. Pull them apart, the bond pulls the atoms closer. For those small displacements, it acts like a spring
The speed of the wave will be related to the stiffness of of those springs - you compress the material - how quickly do all of those little springs rebound and push their neighboring atoms away, sending that wave of compression through the material.
Explanation:
Answer:
Rotational inertia decreases proportional to the decrease in the radius of rotation.
Explanation:
Answer:
The answer is D.
Explanation:
They vibrate parallel to the wave.
During the propagation of a sound wave in air, the vibrations of the particles are most accurately represented as longitudinal. Longitudinal waves are waves in which the motion of the individual particles of the medium occurs in a direction that is parallel to the direction of energy transmission.
