Answer:
Keelboats have been used for exploration, such as during the Lewis and Clark Expedition, but were primarily used to transport cargo or settlers in the early 19th century. The process of moving a keelboat upriver was extremely difficult, though current dependent.The earliest keelboat seems to have been a skiff with a plank nailed the length of the bottom to make the boat easier to steer, but by about 1790 the keelboat had become a long narrow craft built on a keel and ribs, with a long cargo box amidships.

Answer:
the just-world hypothesis
Explanation:
When misfortunes befall a person, others sometimes think the victim of circumstances deserved what happened. One reason put forth to explain why someone would think like that has been called <u>the just-world hypothesis</u>.
The just-world hypothesis is the idea that people need to believe one will get what one deserves so strongly that they will rationalize an inexplicable injustice by naming things the victim might have done to deserve it.
Answer:
170 L
Explanation:
Boyles laws states that the pressure exerted by a gas is directly proportional to the volume it occupies provided that the temperature is held constant. Boyles law is given by:
PV = constant
P₁V₁ = P₂V₂
Given that the initial volume V₁ = 200 L, initial pressure P₁ = 850 atm, final volume V₂ = 1000 atm and final pressure = P₂.
Applying Boyles law gives:
P₁V₁ = P₂V₂
850(200) = 1000(V₂)
V₂ = 170 L
