Answer:
λ = 547.96 nm
Explanation:
given,
thickness of soap bubble = 103 nm
refractive index of thin film = 1.33
using formula of constructive interference
t is thickness of the medium
n is refractive index
m = 0,1,2...
now,
at m = 0
λ = 547.96 nm
at m = 1
λ = 182.65 nm
the only visible light enhanced by the thin film is of wavelength
λ = 547.96 nm
Answer:
The work done is twice as great for block B because it is moved twice the distance of block A
Answer:
Moment of inertia of the flywheel,
Explanation:
Given that,
The maximum energy stored on flywheel,
Angular velocity of the flywheel,
We need to find the moment of inertia of the flywheel. The energy of a flywheel in rotational kinematics is given by :
I is the moment of inertia of the flywheel
On rearranging we get :
So, the moment of inertia of the flywheel is . Hence, this is the required solution.
Explanation:
The water molecules begins to leave their fixed position and begins to move as the temperature increases.
When ice melts, it undergoes a state change from solid to liquid and with increasing temperature becomes a gas.
- The basis for this is the increasing movement of the molecules of the water as it transitions from one phase to another.
- In the ice, the molecules are locked and fixed in the lattice
- As the temperature increases, the average kinetic energy of the particles rises.
- This makes the structure of the ice to collapse and forms liquids.
- By the virtue of this, they flow and move over one another
- With increasing temperature, the bonds are broken and vapor forms
