A 200-gram liquid sample of Alcohol Y is prepared at -6°C. The sample is then added to 400 g of water at 20°C in a sealed styrofoam container. When thermal equilibrium is
reached, the temperature of the alcohol-water solution is 12°C. What is the specific heat
capacity of the alcohol? Assume the sealed container is an isolated system. The specific
heat capacity of water is 4.19 kJ/kg . °C.
O A.. 3.14 kJ/kg • °C
O. B. 3.72 kJ/kg . °C
C. 4.14 kJ/kg . °C
0
D. 4.88 kJ/kg • °C

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

The answer is -6hope this
