The "h" there signifies Planck's constant
Planck's constant is a value, that shows the rate at which the energy of a photon increases/decreases, as the frequency of its electromagnetic wave changes.
It was named after Max Planck who discovered this unique relationship between the energy of a light wave and its frequency.
Planck's constant, "h" is usually expressed in Joules second
Planck's constant =
Answer:
Initial angular position of the disc is 3 radian
Explanation:
As we know that the angular acceleration of the disc is given as
initial angular speed is given as
now we know that angular displacement of the disc is given as
now we have
