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:
0.285
Explanation:
Given two forces of different magnitude, it is important to note that the product of normal force and coefficient of kinetic friction should be equal to the sum of these two forces at equilibrium. Therefore, this can be Mathematically expressed as:

where N is normal force,
is coefficient of static friction, F is force and subscripts 1 and 2 represent larger and smaller magnitude forces respectively. Making
the subject of the formula then

Since normal force N is also given by mg where m is mass of object and g is acceleration due to gravity then substituting N with mg we obtain that
and substituting the figures given in the question, taking g as 9.81 we obtain that

Hence,the coefficient of kinetic energy is 0.285 as calculated
E = 0.5mv^2 = 0.5*44*10^2 = 2200J
