Answer:
She is not getting a good deal.
Explanation:
The equation that relates heat with mass, specific heat and temperature change of an object is 
.
Always convert temperature to Kelvin, although in our case it's not necessary because the 
will be the same, and we will leave the mass in grams because we will be getting 
units for specific heat, which we can compare to the one given for gold.
We then calculate the specific heat of the object in question:
Which shows it's not gold.
Answer:
- Distance is a scalar quantity, defined as the total amount of space covered by an object while moving between the final position and the initial position. Therefore, it depends on the path the object has taken: the distance will be minimum if the object has travelled in a straight line, while it will be larger if the object has taken a non-straight path.
- Displacement is a vector quantity, whose magnitude is equal to the distance (measured in a straight line) between the final position and the initial position of the object. Therefore, the displacement does NOT depend on the path taken, but only on the initial and final point of the motion.
If the object has travelled in a straight path, then the displacement is equal to the distance. In all other cases, the distance is always larger than the displacement.
A particular case is when an object travel in a circular motion. Assuming the object completes one full circle, we have:
- The distance is the circumference of the circle
- The displacement is zero, because the final point corresponds to the initial point
