A flight simulator that helps astronauts prepare for a shuttle launch is an example of a Scientific Model.
Answer: three very important kinds of things: coal, oil, and natural gas.
Explanation:
Answer:
Final temperature of calorimeter is 25.36^{0}\textrm{C}
Explanation:
Molar mass of anethole = 148.2 g/mol
So, 0.840 g of anethole =
of anethole = 0.00567 moles of anethole
1 mol of anethole releases 5539 kJ of heat upon combustion
So, 0.00567 moles of anethole release
of heat or 31.41 kJ of heat
6.60 kJ of heat increases
temperature of calorimeter.
So, 31.41 kJ of heat increases
or
temperature of calorimeter
So, the final temperature of calorimeter = 
So if you take a 39 ft ladder and place its base 15 feet from the base of the wall, when you lean the ladder against the wall, the point where the ladder rests against the wall will be 36 feet above the ground.
Answer: 15 feet
