They believe that a cloud of gas (nebula) starts being pulled together by gravity to the point where it is so small, it starts nuclear fusion. This then start the stars life.
Answer:
301.8 g
Explanation:
We prepare a solution with 200.4 g of water (solvent) and 101.42 g of salt (solute). The mass of the solution is equal to the sum of the mass of the solvent and the mass of the solute.
m(solution) = m(solute) + m(solvent)
m(solution) = 200.4 g + 101.42 g
m(solution) = 301.8 g (we round-off to one decimal according to the significant figures rules)
<span>Dominos are similar in that the movement of one domino causes others to fall, which is a chain reaction. The problem with dominos is that one domino usually causes one other domino to fall which is a linear chain reaction (unless the dominos are set to knock over more dominos as in a fan shape). In nuclear fission of Uranium the reaction is an exponential growth chain reaction. The fission of one atom of U235 releases two or three neutrons which can cause other atoms to split which each release 2-3 neutrons and so on. In this way one split causes 3 splits which cause 9 splits which cause 27 splits and so on. A better analogy is shown in the video where the mousetrap releases 2 balls which set off 2 traps which set off 4 traps.</span>
Answer:
Evaporation happens from the any water body (like ponds, rivers, water stored in cup etc) while the transpiration essentially happens in plants only.
The evaporation and transpiration plays a major role in the water cycle as they help in formation of clouds and precipitation
Explanation:
Evaporation:
It is the process of formation and transfer of the water vapor from the surface of the liquid into the atmosphere.
Transpiration:
It is the process of transfer of the water vapors in the atmosphere from the pores present in the leaves of the plants.
The water is carried from the ground through the stems to the leaves.
The major difference between the evaporation and transpiration is that the evaporation happens from the any water body (like ponds, rivers, water stored in cup etc) while the transpiration essentially happens in plants only.
The evaporation and transpiration plays a major role in the water cycle as these process helps in transfer of the surface water into the atmosphere, which helps in formation of clouds and precipitation.
