Answer:
the amount of orbital angular momentum that an electron has in respect to a particular axis of rotation.
Explanation:
<h2>
Relationship Between Frequency and Period</h2>
The frequency and the period are inversely proportional.
where T is the period
<h2>Solving the Question</h2>
We're given:
- <em>v</em> = 340 m/s
- <em>f</em> = 1000 Hz
Because the frequency and the period are reciprocals of each other, we can find the period of the sound by finding the reciprocal of the frequency:
<h2>Answer</h2>
Answer:
v = 36.667 m/s
Explanation:
Knowing the rotational inertia as
Lₙ = 550 kg * m²
r = 1.0 m
m = 30.0 kg
To determine the minimum speed v must have when she grabs the bottom
Lₙ = I * ω
I = ¹/₂ * m * r²
I = ¹/₂ * 30.0 kg * 1.0² m
I = 15 kg * m²
Lₙ = I * ω ⇒ ω = Lₙ / I
ω = [ 550 kg * m² /s ] / ( 15 kg * m² )
ω = 36.667 rad /s
v = ω * r
v = 36.667 m/s
<h3>Answer;</h3>
A. identity
When water (H2O) freezes into ice, some of the properties have changed but the<u> identity </u>of the H2O is the same.
<h3>Explanation;</h3>
- Water can exist in liquid, solid; ice and gaseous state; steam.
- Freezing occurs when water is continuously cool until it turns to solid ice, water freezes at zero degree Celsius.
- When water freezes the molecules of water have reduced their vibration speed, such that they are now arranged in fixed positions forming a solid.
- Water unlike most substances becomes less dense when it freezes, this explains why ice floats in water as it is less denser than water.
