A Joule's apparatus drops a 72.4 kg hanging mass 156 cm, which causes a stirrer to spin in a sealed chamber
filled with 234 ml of water.
Assuming no energy is lost to the environment,
determine the temperature change of the water. Specific
heat of water = 4186 J/kg•°C.
Q=m-c-AT
1 ml of water equals 1 g.

Where is the diagram? you need to be more specific in your question so we can you

You can find results and justify them? you can test your hypothesis

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
