Answer:5
Explanation:
Given
First Plate has a charge of +Q and area A
Second Plate has a charge of -3 Q and area A
We Know electric Field due to sheet charge is given by
Where Q=charge over the Plate
A=Area of plate
= Permittivity of free space
Electric Field Due to Positive charge will always be away from it while for negative charge it is towards it.
Net Electric Field at a point between between the Plates is the superimposition of two electric with direction
Net electric Field is towards the negative charged plate
Answer:
The value is
Explanation:
From the question we are told that
The number of bright fringes is n = 402
The displacement of the mirror is
Generally the number of fringes is mathematically represented as
=>
=>
=>
Answer: The Earth's layer, which has the covering and layer, is made of a progression of things, or structural plates, that creep after some time. Along these lines, at intersecting limits, mainland outside is made and maritime covering is devastated. 2 plates slippy past each other structures a redesign plate limit.
Answer:
Given:
Mass (m) = 75 kg
Height (h) = 10 m
Acceleration due to gravity (g) = 9.8 m/s²
To Find:
Potential Energy (PE)
Explanation:
The formula for potential energy due to gravity:
Substituting value of m, g & h in the formula:
Because in a compressed gas particles are closer together, so the potential energy is larger, but since potential energy is negative, then the internal energy is lower
Explanation:
The internal energy of a gas is the sum of the potential energy (PE) and the kinetic energy (KE) of the molecules of the gas:
The kinetic energy of the molecules is directly proportional to the temperature of the gas, T, and it only depends on the temperature: therefore, if we take two gases at the same temperature, then their molecules have the same kinetic energy, no matter if their volumes are different.
The potential energy of the molecules in a gas instead is the energy due to the intermolecular forces between the molecules. The closer the particles are in a gas, the stronger the intermolecular forces, the larger the value of the potential energy; however, potential energy has a negative value. This means that for a compressed gas (particles closer to each other), the potential energy is more negative, and therefore the total internal energy E of a compressed gas is less than that of a rarefied gas.
