Osmosis is the net movement of water molecules through a semi-permeable memberane from a region of higher water potential to a region of lower water potential.
so in the first case, since 10% of sucrose solution has a lower water potential than the pure water, so water molecules will flow into the sac, causing the sac to increase in volume. note that sucrose molecules can't diffuse out since there's a semi-permeable membrane.
in the question, I'm not 100% sure what the "sac solution" is meant by, but I guess it's the solution inside the sac
so here if the sac sucrose is 20%, the concentration of water is larger in difference than the first time, so osmosis rate will increase.
but if the "sac solution" is meant by replacing the water of the first case, then the sac inside would have a higher water potential, as the sucrose concentration is more diluted. then the water molecules will flow from the sac back to the beaker or whatever container it is.

An audio-visual element is an electronic media that comprises of both sound (audio) and video (visual) used for teaching or a presentation.
The movement and audio-visual elements of these type of visual aid that capture audience attention are film, videotape, and multimedia.
Being that audio-visual possess both sound and visual components, they're able to foster and enhance deeper knowledge or understanding about a particular subject being played.
Multimedia such as films, videotape, mobile phones, computers, television etc are all audio-visual elements that has a robust graphical user interface and as such it focuses on improving on the cognitive abilities of it's audience or learner.
An audio-visual element basically captures the attention of the audience and keeps them glued, motivated and eager to learn more, as they can both see and hear the information being passed at the same time.
