To solve this problem it is necessary to apply the concepts related to the Period of a body and the relationship between angular velocity and linear velocity.
The angular velocity as a function of the period is described as
Where,
Angular velocity
T = Period
At the same time the relationship between Angular velocity and linear velocity is described by the equation.
Where,
r = Radius
Our values are given as,
We also know that the radius of the earth (r) is approximately
Usando la ecuación de la velocidad angular entonces tenemos que
Then the linear velocity would be,
x
The speed would Earth's inhabitants who live at the equator go flying off Earth's surface is 463.96
Answer:
10 m/s
Explanation:
Given:
Amplitude of atomic vibrations (λ) = 10⁻⁹ cm = 10⁻⁹ × 10⁻² m = 10⁻¹¹ m [1 cm = 10⁻² m]
Frequency of the vibrations (f) = 10¹² Hz
In order to find the atom's maximum speed, we need to make use of the formula that relates speed, frequency and wavelength of the vibration.
Therefore, the formula for maximum speed is given as:
Now, plug in the values given and solve for speed 'v'. This gives,
Therefore, the atom's maximum speed due to thermal energy provided is 10 m/s.
