Answer:
Nothing goes to Kinetic Energy
Both-1, 2, 4
Potential Energy-3 and 5
Explanation:
The correct answer is d. deterioration of brain tissue. A brain ventricle is a fluid filled structure located in the parenchyma. The fluid in the ventricles is called cerebro-spinal fluid. An increase in the volume of this fluid can lead to a condition known as hydrocephalus.
Angular acceleration = (change in angular speed) / (time for the change)
Change in angular speed = (ending speed) minus (starting speed)
Change in angular speed = (16 rad/s) - (zero) = 16 rad/s .
Angular acceleration = (16 rad/s) / (0.4 s)
(Average) angular acceleration = 40 rad/s²
Answer:
The energy in its ground state is 10 meV.
Explanation:
It is given that,
The energy of the electron in its first excited state is 40 meV.
Energy of the electron in any state is given by :

For ground state, n = 1
.............(1)
For first excited state, n = 2
.............(2)
Dividing equation (1) and (2), we get :


So, the energy in its ground state is 10 meV. Hence, this is the required solution.
