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.

andre [41]

Answer:

the frequency is the fundamental and distance is    L = ¼ λ

Explanation:

This problem is a phenomenon of resonance between the frequency of the tuning fork and the tube with one end open and the other end closed, in this case at the closed end you have a node and the open end a belly, so the wavelength is the basis is

          λ = 4 L

In this case L = 19.4 cm = 0.194 m

let's use the relationship between wave speed and wavelength frequency and

           v = λ f

where the frequency is f = 440 Hz

           v = 4 L f

let's calculate

           v = 4 0.194 440

           v = 341.44 m / s

so the frequency is the fundamental and distance is

                  L = ¼ λ

A 1 m3tank containing air at 10oC and 350 kPa is connected through a valve to another tank containing 3 kg of air at 35oC and 15
Sveta_85 [38]

Answer:

- the volume of the second tank is 1.77 m³

- the final equilibrium pressure of air is 221.88 kPa ≈ 222 kPa

Explanation:

Given that;

V_{A} = 1 m³

T_{A} = 10°C = 283 K

P_{A} = 350 kPa

m_{B} = 3 kg

T_{B} = 35°C = 308 K

P_{B} = 150 kPa

Now, lets apply the ideal gas equation;

P_{B} V_{B} = m_{B}RT_{B}

V_{B} = m_{B}RT_{B} / P_{B}

The gas constant of air R = 0.287 kPa⋅m³/kg⋅K

we substitute

V_{B} = ( 3 × 0.287 × 308) / 150

V_{B} = 265.188 / 150  

V_{B} = 1.77 m³

Therefore, the volume of the second tank is 1.77 m³

Also, m_{A} =  P_{A}V_{A} / RT_{A} = (350 × 1)/(0.287 × 283) = 350 / 81.221

m_{A}  = 4.309 kg

Total mass, m_{f} = m_{A} + m_{B} = 4.309 + 3 = 7.309 kg

Total volume V_{f} = V_{A} + V_{B}  = 1 + 1.77 = 2.77 m³

Now, from ideal gas equation;

P_{f} =  m_{f}RT_{f} / V_{f}

given that; final temperature T_{f} = 20°C = 293 K

we substitute

P_{f} =  ( 7.309 × 0.287 × 293)  / 2.77

P_{f} =  614.6211119 / 2.77

P_{f} =  221.88 kPa ≈ 222 kPa

Therefore, the final equilibrium pressure of air is 221.88 kPa ≈ 222 kPa

Light is not a wave because it does not need a medium
Reil [10]
It's a tough question as to whether light is a wave or a particle..

The statement is FALSE. Not all types of waves need a medium to propagate. Light can travel without a medium. 

Extra Information:
Light is a longitudinal wave, sound is transverse.
Longitudinal waves do not need a medium.
Transverse waves need a medium.
This is why, for example, in the vacuum of space, light travels from stars, but sound does not.
