In which position would an object have a greater amount of potential energy
2 answers:
Answer:
At the maximum height
Explanation:
The gravitational potential energy of an object is the energy possessed by the object due to its position in the gravitational field.
Mathematically, it is given by:
where
m is the mass of the object
g is the acceleration due to gravity
h is the height of the object relative to the ground
From the formula, we see that the potential energy is directly proportional to the height of the object above the ground: therefore, the larger the value of h, the larger the potential energy of the object.
Therefore, the object has the maximum potential energy when it is at the highest position above the ground.

Answer:
Energy cannot be changed from one form to another without a loss of usable energy
Explanation:
Second law of thermodynamics states that the total entropy or the randomness of the system remains constant over time. It also states that the net entropy will remain the same or it will increase.
Entropy of a system is given by heat absorbed divided by temperature. It is given by :
So, the correct option is (A) "Energy cannot be changed from one form to another without a loss of usable energy".
