Answer:
force between both the balloons is
Explanation:
It is given charge on both balloons are same and equal to
Separation between both the balloons
According to Coulomb's law force between two charges is given by
Therefore force is equal to
So force between both the balloons is
Answer:
B. An isothermal compression of an ideal gas.
Explanation:
The internal energy of an ideal gas is just function of the temperature; it does not matter what other thermodynamic property changes, if the temperature does not change, the internal energy neither does. That is just for ideal gases; real gases behaviour is not like that. All of the other options bring with them an increase or decrease of the temperature:
For A, the temperature will decrease because the gas will do work as it expands, converting part of his internal energy to work.
For C, the temperature will increase, because given , if the volume increases (expansion) and the pressure is constant, the temperature must increase to satisfy the equation.
Answer:
The angular separation between the red and violet components of the spectrum that emerges from the glass is 1.72°
Explanation:
Given:
Refractive index for red light
Refractive index for violet
Refractive index for air
Incident angle 28.30°
According to the snell's law,
For red light,
Where transmitted angle for red light
50.18°
For violet light,
Where transmitted angle for violet light
51.9°
Angular separation between red and violet light is given by,
1.72°
Therefore, the angular separation between the red and violet components of the spectrum that emerges from the glass is 1.72°
