The change in gravitational potential energy is A) 15.68 J
Explanation:
The gravitational potential energy of an object is the energy possessed by the object due to its position in the gravitational field.
The change in gravitational potential energy of an object is given by the equation:

where
m is the mass of the object
is the acceleration due to gravity
is the change in height of the object
In this problem, we have
m = 2 kg is the mass of the frame
is the change in height
Substituting, we find:

<span>The correct option is: (A) 41 °F (5°C)
Explanation:
As the temperature increases (from 6-7 °C), the tendency of a bacteria to grow also increases. Therefore, it is recommended to keep the temperature of refrigeration units, salad bars and other cold items at 41 °F (5 °C) or colder. Hence, the correct answer is option (A).</span>
