Scientist infer that most of earth earliest atmosphere was produced by?

Answers

Answer 1
Answer: Scientists infer that most of Earth earliest atmosphere was produced by the escape of gases from Earth's molten surface. Once these gases were released from the very hot surface that covered the Earth, the earliest stages and levels of the atmosphere we know today were created. Many of those earliest gases still make up our atmosphere today.Hope this helps. Let me know if you need additional help!

Explanation:

Earth shaped through a method of accretion -collision of rocks and dirt particles, that step by step shaped a bigger and bigger object. These impacts generated loads of warmth, therefore early Earth would are a hot and desolate place. Vapour is assumed to own shaped a steam atmosphere, and incoming iron-rich rocks colliding with Earth would have reacted with a number of this water to provide rise to H gas.

What is the potential of a 35kg child sitting at the top of a slide that is 3.5m above the ground? What is her kinetic energy if she moves down the slide at a speed of 5.0m/s??

Answers

Ep = mgh
     = (35)(9.8)(3.5)
     = 1200.5 J

Ek = (1/2)(mv^2)
     = (0.5)(35)(5^2)
     = 437.5 J

The change in pitch of a train's horn as it passes while you are standing still can be explained by A. the Doppler effect.
B. ultrasonic vibrations.
C. sympathetic vibration.
D. resonance.

Answers

The change in pitch of a train's horn as it passes while you are standing still can be explained by the Doppler effect. The correct option among all the options given in the question is option "A". When the sound source from the horn of the train comes closer, the sound seems to come closer each time a sound wave gets emitted. So it comes closer to us in a bunched form. The reverse happens when the train has just passed with each emitted sound going further and further away. The frequency of the sound seems to get lower as the train moves further away.

Find the percentage of the total work lost to friction if 28.7 J of work is put into pushing a block up a ramp resulting in 14.2 J of stored potential energy at the top.

Answers

Answer:

14.5 joules

50.5 %

Explanation:

Energy initial +work= energy final

28.7 + work = 14.2

friction did - 14.5 joules of work so percantage of work lost is just 14.5/28.7 *100 or 50.5 %
