Answer:
answer it by yourself and own way
Answer:
Velocity = distance / time
if distance is same and time is 1/2
Velocity = distance / time/2
velocity = 2 (distance /time)
Velocity,= 2 * velocity
Velocity will be doubled
Answer:
B) There is more water in the air because the rate of evaporation increases
Explanation:
As the temperatures rise across the globe, the rate of evaporation also increases, resulting in more water in the air. The reason for the increased evaporation is that the ice sheets and glaciers are melting, thus there's more liquid water. The more liquid water there is, the more evaporation there will be. As the evaporation increases, there will be an increase in the formation of clouds, thus there will be more precipitation around the world, gradually leading to warmer and wetter climate.
If you add a surfactant in water-oil mixture, surfactant molecules would form micelles wherein the hydrophobic end of the surfactant faces inside the micelle while the hydrophilic end faces the water molecules. Inside these micelles oil particles are attached.
Answer:
If More solute is added and it does not dissolve,then the original solution was saturated. if the added solute dissolves,then the original solution was unsaturated. A solution that has been allowed to reach equilibrium but which has extra undissolved solute at the bottom of the container must be saturated.
