Answer:
Flappers are symbols of the Thundering Twenties, the social, political disturbance and expanded transoceanic social trade that followed the finish of World War I. Flappers were viewed as reckless for wearing inordinate cosmetics, drinking liquor, smoking cigarettes in broad daylight, driving vehicles and treating sex nonchalantly. They guaranteed that the flappers' dresses were 'close to exposure', 'nervy', 'foolish', and unintelligent.
Answer:
371.2 mm
Explanation:
The Balmer series of spectral lines is obtained from the formula
1/λ = R(1/2² -1/n²) where λ = wavelength, R = Rydberg's constant = 1.097 × 10⁷ m⁻¹
when n = 15
1/λ = 1.097 × 10⁷ m⁻¹(1/2² -1/15²)
= 1.097 × 10⁷ m⁻¹(1/4 -1/225)
= 1.097 × 10⁷ m⁻¹(0.25 - 0.0044)
= 1.097 × 10⁷ m⁻¹ 0.245556
= 2.693 10⁶ m⁻¹
So,
λ = 1/2.693 10⁶ m⁻¹
= 0.3712 10⁻⁶ m
= 371.2 mm
Answer: W represents an element Y represents a mixture
Explanation: I just took a quiz on this and got it right. Good Luck
The sun was shining on the sand heating it up causing ot to become hot
Answer:
There is no exception to this. all planets have some eccentricity. it is physically impossible to have an orbit without any eccentricity. However, venus's orbit has the lowest (0.007) eccentricity (closest to circular) so that could be your answer.
Mercury's orbit's eccentricity 0.2
Venus's orbit's eccentricity 0.007 (this is the lowest so it may be your answer)
Earth's orbit's eccentricity 0.0167
Mars's orbit's eccentricity 0.0934
Jupiter's orbit's eccentricity 0.0489
Saturn's orbit's eccentricity 0.0565
Neptune's orbit's eccentricity 0.009
Uranus's (yur,in,iss) orbit's eccentricity 0.0457
Pluto's (not really a planet) orbit's eccentricity 0.2444 (very high)
hope it helped.
