Answer:
The angle is 23.2 radians, equivalent to 3.69 revolutions.
Explanation:
First, we need to find the angular acceleration of the wheel. This can be done using one of the kinematic formulas:
Since the final angular velocity is zero after 5.5 revolutions (equivalent to 11π radians) we have that:
Now, using the same equation, we can solve for the requested angle:
Finally, it means that the angle through which the wheel has turned when the angular speed reaches 1.80 rad/s is 23.2 radians, equivalent to 3.69 revolutions.
Answer:
width of slit =1.23× 10⁻⁶ m
Explanation:
we know the condition of diffraction minima,
d sin θ = n λ
λ = wavelength θ = angle between the central maxima and 1st minima
d = slit width
for first minima n = 1
now,
d =
d =
d = 1228 × 10⁻⁹ m = 1.228× 10⁻⁶ m
d = 1.23× 10⁻⁶ m
width of slit =1.23× 10⁻⁶ m
A giant (massive) planet close to the star is expected to cause the largest Doppler shift in the star's spectrum.
<h3>What is the Doppler Shift Method for Detecting Exoplanets?</h3>
- Doppler spectroscopy is used to capture periodic velocity shifts in stellar spectra caused by orbiting giant planets. (This method is also known as the radial velocity method.)
- The Doppler method, which is most commonly used to find exoplanets, is most suitable to look for very massive planets orbiting near their parent stars
<h3>What does the Doppler method tell us about planets? </h3>
The Doppler shift data can tell us something about the mass of the planet and the shape of its orbit. Since the Doppler shift only knows how fast it approaches and moves away from Earth, it is not possible to determine the exact mass of the planet without knowing the inclination of its orbit. Doppler data give a lower bound on mass.
