It rotated by 11 degrees per hour.
phase shift in integrator is 180 degrees and phase shift in differentiator is 0 degrees
There is a Doppler shift which results from the relative motion of the star in question, either toward or away from us as we observe it.
A) Rotate 360 degrees counterclockwise, then shift 1 unit up. B) Rotate 180 degrees counterclockwise, then shift 1 unit down. C)Rotate 90 degrees counterclockwise, then shift 1 unit up. D) Rotate 270 degrees counterclockwise, then shift 1 unit down.
Press Shift>Option>8
In order for an oscillator to be stable, its total phase shift must be 180 degrees. The most common design of an RC phase shift oscillator is three identical RC stages in series, which means that each stage contributes 60 degrees. For more information, please see the Related Link below.
In that case, the star must be approaching us.
60 Degrees
In a Kater's pendulum, the heavy mass is placed at one end to lower the center of mass of the pendulum system. This helps in reducing the effect of air resistance and friction, allowing the pendulum to swing more freely and with less interference. By lowering the center of mass, the period of the pendulum becomes more consistent and accurate, making it a reliable tool for measuring gravitational acceleration.
The pendulum swing in teaching refers to the dynamic shift of focus between different educational approaches over time. It reflects the cyclical nature of trends in teaching methods, such as moving between traditional and progressive approaches. Educators must be aware of this pendulum swing to adapt their teaching practices and incorporate a balance of effective strategies that best meet the needs of their students.

Scientists can observe red shift using a spectrometer or a telescope equipped with a spectroscope. The spectrometer will measure the shift in wavelength of light emitted by celestial objects, which can indicate the red shift. Additionally, precise and sensitive telescopes are needed to capture high-quality data for accurate red shift measurements.
