Answer:
v = ω R
number of seconds in 24 hrs = 24 * 3600 = 86400 s / da = T (period)
f = 1 / T
ω = 2 Π f = 2 Π / T = 2 Π / 86400
v = 2 Π / 8.64E4 * 6.0E6 = 436 m / s
Check:
S = 2 Π * 6.0E6 = 3.77E7 m/da
S / T = 3.77E7 m/da / 8.64E4 s/da = 436 m / s
Answer: GREATER
Explanation:when elevator does not move it reads weight of the person . when elevator moves up let apparent weight be F . W acts downwards so net force is F-W
HENCE
F-W =ma
F= ma+W
AS a= 1 m/s^2
F = m (1)+W
HENCE GREATER
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.
