Answer:
(1)
And we have this other relationship between the linear speed and the angular speed:
(2)
We can find the linear velocity like this:
And then from equation (1) we can solve for the frequency and we got:
And replacing we got:
And that represent the wavelength in th groove for this case.
Explanation:
For this case we have the following data given:
represent the angular velocity
represent the frequency
we assume that this respresent the distance from the center
We know the following relationship between the wavelength and the velocity of a wave:
(1)
And we have this other relationship between the linear speed and the angular speed:
(2)
We can find the linear velocity like this:
And then from equation (1) we can solve for the frequency and we got:
And replacing we got:
And that represent the wavelength in th groove for this case.
Solids almost every single time
Gases have heavier molecules. Since all gases have the same average kinetic energy at the same temperature, lighter molecules move faster and heavier molecules move slower on average.
<span>1) The resistance force relate to the effort force for the fixed pulley alone be being equal to the effort force. resistance force = effort force. 2) The mechanical advantage compare with the slope of the line for each pulley by being independent of slope. </span>
