time = dist/speed
Find the time it takes turtle to cover 100ft
<span> = 100/20= 5 minutes
</span>
Find the time (t.) for the rabbit to cover 100ft
<span>t. = (50/40)</span><span> + 3 + (50/40)</span>
<span>t. = 1.25 + 3 + 1.25 </span>
<span>t. = 5.5 min
the turtle won the race by 0.5 minutes</span>
Answer 1:
England had forbidden slavery for ages and despite in Maryland and Virginia, they envisioned the demand for labor in tobacco fields in the 1660s they required to reevaluate order though.
An emerging metropolitan lifestyle led to both possibilities and limitations for immigrants, minorities, and females.
Cross-country tracks increased western migration, frightening the culture, personality, and very survival of Native Americans.

Answer 2:
British viewed Native Americans as an obstruction to their financial prosperity and the religious path to fairness
In many circumstances, the British traded with local societies and relied on them to acquire professions of agriculture, fishing, and netting in the geographical area. Natives responded in one of three ways: tolerated, supported, or converted reliant on. The was a grand opportunity for miscommunication among the two groups often commencing to contend. Very distinctive spiritual faiths. British often tried to manage and misuse the Native Americans for financial profit.
Native Americans were very defenseless to European epidemics that decimated their community.
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.
