Answer:
Vibrating means to move quickly to and fro.
Explanation:
With angular momentum quantum number l = 2. in units of ħ, the value of l will be 2.4494 h.
<h3>What is the angular momentum quantum number?</h3>
The total angular momentum quantum number in quantum mechanics parametrizes the total angular momentum of a particular particle by combining its orbital angular momentum and intrinsic angular momentum.
Given the angular momentum quantum number l = 2. in units of ħ. Therefore, the value of L can be written as,
L = √[l (l + 1)]
L = √[2 (2 + 1)]
L = √[2 (3)]
L = √6
L = 2.4494 h
Hence, With angular momentum quantum number l = 2. in units of ħ, the value of l will be 2.4494 h.

B. the current in the circuit divides so that some flows through one component
The distance of the Image will be -33.75 cm
A concave mirror has an inward-curving reflecting surface that faces away from the light source. Unlike convex mirrors, a concave mirror's image forms a variety of images based on the object's proximity to the mirror.
Given that, an object placed 27 cm from a concave mirror having the focal length of 15 cm
We have to find distance of the Image
Using Mirror Formula:
1/f = 1/v + 1/u
Where,
f = focal length
v = Image distance from the mirror
u = object distance from the mirror (concave)
Substitute the known values in the above formula to find the value of 'v' i.e. from the mirror.
1/(-15) = 1/v + 1/(-27)
1/(-15) = 1/v - (1/27)
1/v = -0.029
v = -33.75 cm
Therefore the distance of the Image will be -33.75 cm

1. Rainbow (white light is split into its subsequent wavelengths)
2. Light enters through the cornea, is adjusted by the lens, the cones and rods of the retina are responsible for the perception of color and shadows, which are sent through the optic nerve to the occipital lobe of the brain.
3. Sound waves are intercepted by the pinna, travels through the auditory canal, reverberates on the eardrum, the vibrations travel through the ossicles of ear (hammer, anvil and stirrup), continuing to the cochlea and are sent through the auditory nerve to the brain.
4. A medium
5. Vibrations
6. All
7. Faster
8.Their kinetic energy increases
9. Conduction, convection and radiation
10. The heating of metals in the mantle, creates a current which slowly moves the plates above it.
