Which stage of atmospheric evolution is characterized by conditions rich in water vapor and carbon dioxide?

Physics
1 answer:
Anni [7]3 years ago
5 0

Answer: Option A: Atmosphere II

Atmosphere I consisted of gases: mostly hydrogen, water vapor, methane and ammonia. Thereafter, with the out gassing of volcanoes and bombardment of earth by asteroids, gases like nitrogen, carbon-dioxide etc. characterized our atmosphere leading to atmospheric evolution: atmosphere II. Hence, stage II of atmospheric evolution was characterized by conditions rich in water vapor and carbon-dioxide.

What types of natural phenomena could serve as time standards?
Delvig [45]

Answer: The rising and setting of the Sun.

The appearance and disappearance of the Moon.

Changes in season.

Appearance and disappearance of the Stars.

Explanation: The rising and setting of the Sun helps can be used as a standard to determine time since the rissing and setting of the Sun occurs at similar time and interval in a given geographical ocation.

The appearance and disappearance of the Moon which occurs during the night and early hours of the morning is similar in a given geographical locationation so it can be used as a standard for Time.

Change in season is another natural phenomenon which occurs at similar times in a given geographical location like Winter/summer, rainy/dry etc can be used as standards for time.

The appearance and disappearance of the Stars can also b used as standards for time in a given geographical location.

A pair of electrically charged objects attract each other with a force of 4 N when they are a distance of 3 m apart. If their ch
Rainbow [258]

Answer:

1 N

Explanation:

From coulomb's law,

The force of attraction between two charges is inversely proportional to the square of the distance between the charges.

From the question,

Assuming the charges are the same in both case,

F ∝ /r²....................... Equation 1

Fr² = k

F'r'² = Fr²........................... Equation 2

Where F' = First Force, r'² = First distance, F = second force, r² = second distance.

make F the subject of the equation,

F = F'r'²/r².................... Equation 3

Given: F' = 4 N, r' = 3 m, r = 6 m

Substitute into equation 3

F = 4(3²)/6²

F = 36/36

F = 1 N
