Which chemical in the atmosphere of titan (a moon of saturn) appears to play the same role that water plays on earth in producing “rain” and forming lakes and streams, at the temperature encountered on the moon?

Methane

Explanation:

Saturn is the least dense planet of the Solar system. It has about 62 moons. Saturn is known for its beautiful ring system. Titan is the largest moon. It has a very dense atmosphere and the only moon in the solar system to have so. Its atmosphere is composed of mostly Nitrogen, Methane and Hydrogen.

Just like the water cycle on the Earth, the largest moon of the Saturn, Titan has Methane cycle. There are lakes and streams of hydrocarbons such as methane on its surface. The clouds are formed of methane which later pour down as rain.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
